The Umarex EBOS – Part 3

by B.B. Pelletier

Part 1
Part 2

The new EBOS is a loud, powerful BB submachine gun.

Today, I’ll finish the test of the Umarex Electronic Burst of Steel — the Umarex EBOS. This is accuracy day, and the test runs exactly as it has for the other two BB submachine guns I’ve tested — the HK MP5 K-PDW and the Umarex Steel Storm. That means 10 aimed shots at 15 feet on semi-auto, followed by several bursts of full-auto fire.

I have three BBs to test today, and the EBOS brings us a complex set of operating parameters. You can select from either one shot, which simulates semiautomatic fire, a 4-shot burst or an 8-shot burst. But there’s also the rate of fire to select. It can be set for 300, 400 or 500 rounds per minute (RPM). I discovered very quickly that 300 RPM is too much like shooting an M3 grease gun, which bounces around in your hand without much possibility for accurate aimed fire. So I did what every EBOS owner will eventually decide to do. Set it to 8-shot bursts and 500 RPM. Once I did that, I made no attempt to test the other rates or the lower burst count. Nor would a cigarette boat owner use a trolling motor for better fuel economy!

At first
In the beginning, I was just trying to adjust the rear sight so the groups would be centered on the bull. The rear sight is fiddly and I found it difficult to adjust. When I shot, I felt the rear notch was too close to my eye for good accuracy, but the gun proved me wrong on that count. I’ve had the same problem with 9mm MP5s, and they always seem to hit their target as well. Apparently, mine are just the ramblings of an old dog who cannot learn new tricks.

Once the rear sight was centered in adjustment, the gun shot to the point of aim. I wish there was an elevation adjustment on the rear sight as well, but I suppose most owners will slap a red dot on the top Picatinny rail and be done with it.

Crosman Copperhead BBs
The first BBs I tried were Crosman Copperhead BBs. As I fired 10 semiauto shots, I was impressed by how smooth the EBOS trigger is. That’s no doubt due to the electrical drive unit in the pistol grip. All the trigger has to do is make contact and the gun fires.

The first group was impressive, especially in light of the tests of the other two guns. You can’t even see 10 holes in the target, but one hole at the bottom of the group is clearly larger than the rest, and apparently swallowed four BBs.

An impressive group that demonstrates the EBOS stability in the semiauto mode.

Then, I switched to rock ‘n’ roll. I first tried 300 RPM rate of fire and a 4-round burst, but it soon became obvious that wasn’t the way to go. So, all the switches were set to the max, and that’s the way the rest of the test was conducted.

Compared to the other tests, this constitutes a screamer target for full-auto.

Daisy zinc-plated BBs
Next, I loaded Daisy zinc-plated BBs and ran a second 10-shot semiauto test. Oh, my gosh! I got accuracy that’s not too far from the Avanti Champion 499 target gun! And this was with the sights I was complaining about! Imagine what this gun could do with dot sights!

Now, THAT is a group! For a BB gun, you aren’t going to do much better.

At this point, I was wondering what would happen when I switch over to warp drive. Well, you know the answer. I switch and the gun continued to group tight. I kept shooting and reloading, shooting and reloading. At this point, my test design was blown because I hadn’t tested the other two guns the same way, nor am I going to. But I figured a part of this evaluation was the fun factor, and any day you can keep my finger on the trigger of a full-auto gun, you know I must be having fun!

Holy cow! I’m not that good a shot. This gun shoots like it has radar or something.

Finally it came time to test the new RWS BBs. You may recall from the Steel Storm test that these BBs were almost as good as the Daisy zincs, and I said that more testing would be needed. Well, look at what happened with the EBOS.

Every bit as tight as the Daisy target on semiauto fire.

When I switched to overdrive with the RWS BBs, something wonderful happened. The group stayed the same size. It just has about four times as many BBs through it. I could not stop shooting, and I know the full-auto group has at least 40 rounds in it.

Oh, boy! Now we’re having fun!

Crosman 850 trap
Wow! It’s been a while since an airgun made me smile like this one does! And do you remember that I said I would be using the Crosman model 850 BB trap for this test? Well, I did, and despite the power of the EBOS, the trap did not suffer one bit.

So, now I’ve tested all three BB submachine guns completely. And here’s my assessment. The Steel Storm is the best value, but the EBOS is THE boss!

H&K MP5 K-PDW CO2-powered BB gun – Part 3

by B.B. Pelletier

Part 1
Part 2

Umarex HKMP5-K-PDW is a lightweight, handy BB-firing semiauto.

Today, I’ll begin the accuracy testing of all three of our BB submachine guns, beginning with the first one I tested, the HKMP5-K-PDW.

This gun is semiauto only, so there are only two settings on the selector switch — fire and safe. On fire, you get one shot per pull of the trigger, which is semiautomatic fire.

The trigger-pull is long and somewhat heavy but without any creep. You just feel the movement of the trigger blade until the gun fires. Creep is that nasty start-stop hesitation in a pull that messes with your concentration, and this gun has none of it.

You may remember that I commented on the rear sight being all wrong for this gun. For some reason, the maker put notches in the back instead of the MP5 apertures. You cannot see a notch when it’s so close to your eye, and I assume some of the openness of the groups I got is due to the imprecision of the sight picture. This would have been so easy to fix in the design stage, but now it’s a hindrance for accurate shooting. Not that most people will be using the sights, which are non-adjustable. Submachine guns are meant to be fired from the hip in close assaults. They’re not a precise weapon, although I do admit that the groups that use the MP5 firearm are being trained to use the sights with great effect. But they don’t use notches this close to their eyes!

I need to make one more observation before getting to accuracy. As I loaded a fresh CO2 cartridge into the gun, the tightening screw happened to stop just after the cartridge was punctured. I wasn’t ready for it, and I lost about a quarter of the gas charge while I repositioned my hand to tighten the screw further. This is the same complaint other owners have made, only they pierced the cartridge only to have it loosen during operation. For some reason, the face seal that contacts the small end of the CO2 cartridge on this gun is unlike all others that simply swell and seal the gun instantly when the cartridge is pierced. You can overcome this by learning to hold the winding screw in such a way that you can continue to tighten it all the time, but it is bothersome.

For this test, I shot 10s round offhand from 15 feet, which is close to the distance used in international BB gun competition (16.4 feet). As I mentioned, the rear sight notch was very hard to see, and I had to hold the stock funny so I could hold my head as far back on the comb as possible. Each shot was deliberate, and I took great pains to hold the sights at six o’clock on the bull.

Crosman Copperheads
The first BBs I tried were Crosman Copperheads. They shot exactly to the point of aim, more or less, which was gratifying. I kept the six o’clock hold only because it’s more precise than trying to guess where the center of a dark bullseye is.

Crosman Copperhead BBs shot to the point of aim at 15 feet, but the group was extended vertically. Party of this is due to the difficulty of seeing the rear notch that’s placed too close to the eye to resolve. Group measures right at two inches vertically but only one inch horizontally.

Daisy zinc-plated BBs
Next, I loaded 10 Daisy zinc-plated BBs into the stick magazine. You’ll recall that Daisy BBs are ever-so-slightly larger than Copperheads. They also shot to the aim point and gave me a group that was more rounded than the Copperheads. This group measures just larger than 1-3/8″ and is wider than it is tall. So, the vertical stringing is not due to the sights like I originally thought.

Daisy BBs gave the tightest group of this test. They also shot to the point of aim at 15 feet and did not string out nearly as vertical as Crosman Copperheads.

As a surprise, I also shot a group with RWS BBs, which I told you appear to be made as uniform as ball bearings. I’m definitely going to give this BB a test for ultimate accuracy some day soon. However, in the HK MP5, they lagged behind the Daisys, due to a single flyer. I didn’t call that flyer, so we must assume the BB went where it did on its own. If we discount that single BB, the RWS BBs equalled the Daisys with a 1-3/8″ group, so I’m hopeful they’ll continue to make a good showing in future tests. Pyramyd Air doesn’t carry RWS BBs yet, but if I can give them a good reason with these tests, I know they’ll reconsider it.

A great target, if only that one shot up away from the main group can be discounted. Certainly, RWS BBs are going to get a lot more testing from me in the near future.

Overall impressions
If it had no competition, I think the HK MP5 would do very well. Its one big drawback is the lack of a full-auto burst-fire mode that the other two guns (the Steel Storm and the EBOS) have (three, if you count the Drozd). I like the trigger, and the power level is much greater than advertised. But the method of loading the CO2 cartridges requires too much work, and the sealing issue when piercing the cartridge that I mentioned in this report is bothersome. However, if you want a gun with just semiautomatic fire, this is the only BB submachine gun that has it.

The Umarex EBOS – Part 2

by B.B. Pelletier

Part 1

The new EBOs is a loud, powerful BB submachine gun.

Well, this report is somewhat overdue, but I’ve been waiting for some of the new RWS BBs to test for you, because of some good things I’ve heard about them. Looking at these BBs under a 10x loupe, they appear smoother than even the Daisy precision ground shot made for the 499 BB gun.

I plan to test this shot in several ways for you with guns we have a baseline on. But that will be later. Today, we’ll look at the Umarex EBOS velocity. And velocity it has! The specs say 540 f.p.s. and by golly that’s what I saw!

The EBOS is run by a battery-powered electric motor, so many of you are considering it as a replacement for the Drozd. I’m no expert on the Drozd, but I’ll report on the EBOS as it operates similar to the Drozd and let you judge for yourselves. What I mean by being run from a motor is that the firing function is controlled by that motor. The power that propels the BB comes from CO2, of course, and the EBOS uses the big 88-gram CO2 cartridges that give hundreds of shots. But the electric motor takes care of firing the gun once you pull the trigger.

A word on loading
The EBOS has a large BB reservoir that’s used to fill up a smaller forced-feed magazine located on the left side of the gun when you take action to fill it. When it’s full, you have up to 24 shots available. After that, you must manipulate the larger reservoir to refill the magazine. This process goes very quick and easy with no jams noted in my test. If you take the time to look inside the large reservoir when it’s empty, you can see the hole that connects it to the BB magazine, so you’ll know what to do to load the gun. But no worries — both loading and unloading are easy!

Get ready for magnum power with the EBOS, because it really delivers on its promises. While that may evoke some smiles, it also means you must take extra care to prevent ricochets and bouncebacks, because they’ll be both painful and dangerous. Eye protection is mandatory for everyone in the area and the eyewear MUST be a pair of certified safety glasses. Regular prescription glasses will turn to dust with a single shot from this gun.

For this test, I shot into a Quiet pellet trap, because a regular BB trap like the Crosman model 850 is a little on the light side for a gun this powerful. Please understand that I was shooting at less than 24 inches from the trap in my office. When I move back to 15 feet for the accuracy test, I DO plan to use the Crosman 850. But, at this close range, the velocity is too high for a steel BB that could rebound. I waited between 15 seconds and 30 seconds per shot. The one time that I shot a shot right away, the gun lost 20 f.p.s. Remember the lesson of the cooling effects of CO2.

Daisy zinc-plated BBs
The first BBs tested were Daisy zinc-plated BBs. They averaged 539 f.p.s., and the spread went from 528 to 548. So, right there, the EBOS met its advertised velocity. By the way, that works out to a muzzle energy of 3.29 foot-pounds.

Crosman Copperhead BBs
Next to be tried were Crosman Copperhead BBs, which are a little smaller and a trifle lighter than the Daisys, though both are listed at 5.1 grains. Copperheads averaged 523 f.p.s. and ranged from 503 to 532 f.p.s. This was the BB that I shot right away after the last shot, which gave me the low reading of 503 f.p.s. They produced an average 3.1 foot-pounds of muzzle energy.

RWS Match Grade BBs
That’s quite a claim in the name of these BBs, but after examination I must say they look as uniform as ball bearings. Pyramyd Air doesn’t carry them at the moment, but that could change. These BBs all weigh 5.2 grains, with no variation. In the EBOS, they averaged 504 f.p.s., with a spread from 498 to 521 f.p.s. We’ll see how well they shoot in the accuracy test, plus I’m going to test them in the Steel Storm and the HK MP5 as well.They produced an average of 2.93 foot-pounds of energy at the muzzle.

Shooting impressions
The EBOS trigger is very smooth. It’s a long single-stage pull with no warning before the break. You’ll feel some recoil with this gun, as there’s so much gas pushing out the barrel with every shot. The fastest rate of fire goes higher than an M3 grease gun, so the gun is very controllable. I believe it’ll be an easy gun to hit with. And I like the sights. Although the stock pull is okay at 13.75 inches, the rear sight notch is too close to the sighting eye. However, I think I may get some good accuracy from this gun because of these sights anyway.

The EBOS is powerful and loud! Respect the power and shoot safely at all times. Don’t use hard backstops such as trees, because the BBs will bounce back wildly. And, enjoy the noise! On the fastest rate, which is 500 rpm, the bursts sound very realistic.

The Umarex EBOS – Part 1

by B.B. Pelletier

Well, it was inevitable. Just as I was reporting on the Umarex Steel Storm, somebody said they had heard that the new Umarex EBOS (Electronic Burst of Steel) was the better BB submachine gun. If you go looking for the EBOS, don’t look among the air pistols. Even though the firearm it is copied from probably fires a pistol cartridge, the presence of a fixed shoulder stock has caused Pyramyd Air to place this BB gun among the rifles.

There will probably be debate over which of these three new BB submachine guns is the best for a long time to come. I won’t get into that, but I’ll review the same things on all of them so you can make up your own mind.

And a word on the accuracy testing of all three guns. I have ordered some RWS BBs that one reader praised for extra accuracy. I want to include these BBs in the accuracy tests of all three guns, plus I will also test the Daisy No. 25 BB gun. If there’s a good enough result, I will show it. I will not test them with Daisy Avanti BBs because of the price and the fact that these are submachine guns.

For those of you who were wondering where the Drozd fits in among these new BB submachine guns, the EBOS would seem to be its direct competition. It has an electrically driven action that allows for two sizes of automatic bursts as well as semiautomatic fire. It also offers three rates of automatic fire during the two bursts — 300, 400 and 500 rounds per minute.

Three rates of fire are selectable. Semiautomatic fire (one shot per pull of the trigger) is selected by a different switch on the other side of the gun.

In reading the user comments, I see where someone has requested that the cyclic rate be increased to 800 r.p.m., so perhaps this gun will seem realistic to me after all. If it is, it will be much more to my liking, because I was trained on automatic firearms that shot from 400 to 900 r.p.m. I don’t relate very well to the “carpet-rippers,” as the high-rate guns are often called.

The EBOS advertises a muzzle velocity of 540 f.p.s., which, if true, will make it the hottest BB gun I’ve ever tested. The previous record-holder was an Anics pistol that’s been obsolete for about five years. A velocity this high in a BB gun is almost a liability, what with the way steel BBs ricochet. I’ll have to give some thought to how this gun needs to be tested, lest I blow through my Crosman 850 BB trap.

The EBOS uses 88-gram CO2 cylinders, or what Crosman likes to call AirSource cartridges. Of course, you don’t want to forget that Umarex has their own Walther-brand cartridges. These larger cylinders fit into the part that becomes the stock of the gun. The gun features a built-in, 24-shot forced-feed BB magazine fed from an onboard 400-shot reservoir.

Just pour in up to 400 steel BBs.

Now I am going to do something I almost never do, but in this case the facts are so blatant that they warrant a comment. The price point of the EBOS is so much lower than the Drozd Blackbird that I seriously wonder if it is going to cut into the sales of the Russian gun. Usually, when there’s a small difference, even up to $50, there wouldn’t be much competition, but the EBOS is nearly one-third the cost of the Drozd Blackbird, which also accepts 88-gram cartridges. That may change demand in the market.

Some design features explained
Of course, this gun is mostly plastic on the outside and very lightweight — 3 lbs. without BBs and a CO2 cartridge installed. And I want to draw your attention to two design features that are visually misleading. What appear to be Picatinny mounts on both sides of the gun are simply decorative embellishments. They will not hold any thing. The two true Picatinny rails are on top of the receiver and at the bottom. Also, what appears to be a thread pattern behind the muzzle is actually a series of concentric plastic circles that do not accept any muzzle attachments.

Although the sides of the gun appear to have Picatinny rails, they’re simply decorative. The real Picatinny rails are at the top and bottom of the gun.

Sights adjust
There has been some criticism of the top-loaded BB reservoir, and I don’t understand why. The adjustable sights clear it fine and so will most dot sights. It isn’t a hindrance in any way I can see. The rear sight is adjustable for both windage and elevation, and I can’t wait to try it out. This is the only one of the three BB submachine guns I’m testing that has a stock. That makes the open sights workable.

The rear sight adjusts in both directions.

The EBOS seems to be the biggest and baddest of the three newcomers. But testing will show all.

H&K MP5 K-PDW CO2-powered BB gun – Part 2

by B.B. Pelletier

Part 1

Umarex HKMP5-K-PDW is a lightweight, handy BB-firing semiauto.

Well, now that I’ve shot the HK MP5 K-PDW, I have a greater appreciation of what it is and how it functions. The stock removal required to replace the CO2 cartridge is troublesome but not time-consuming. However, while I was shooting, the CO2 started to leak, causing me to have to tighten up the screw that puts tension on the CO2 cartridge. This is the first time I’ve ever had to do this in tens of thousands of CO2 cartridges, and it was unexpected, except that I read about it in the customer reviews when they rated the gun. So, I suspect this behavior is common to this gun.

The stock pins are now worn in enough to easily press out with my fingers. They’re still difficult to align when putting the stock back on the gun, but a plastic hammer will tap them into place quite readily.

Don’t do this!
Now let me tell you a weakness of this CO2 cartridge installation system. When I loaded a cartridge I forgot to loosen the screw all the way before pushing the pins back in the stock, and I pierced the cartridge as I was installing the pins. It is written clearly in the owner’s manual to not do this, but I thought I knew what I was doing. So, I exhausted an entire cartridge with no effect. Remember to back off the CO2 piercing screw each time you remove a CO2 cartridge, and you won’t have this problem.

This screw pushes the CO2 cartridge into the piercing pin. Don’t forget to unscrew it all the way before you put the stock back and push the pins in place, or it’ll pierce the fresh cartridge before you’re ready.

Number of shots per cartridge
I got about two complete magazines per CO2 cartridge, but the last shots were not in the same power band as those in the first magazine. They were still in the 300 f.p.s. range and above, though, which makes them credible shots on a close-range course. The real drop-off doesn’t occur until a third magazine is attempted, so don’t try it.

I found loading was easy and straightforward. The follower release is located on the bottom of the magazine, and until I found it I couldn’t get the follower to move. But once found, the button works fine. So, familiarization with the gun is important. However, loading takes long enough that I can see why owners want to buy extra magazines for their guns. It would be so simple to pop out a spent mag and replace it with a full one. And since you get two mags worth of shots per cartridge, it seems like two mags are the ideal number to have.

Velocity testing
I tested both Daisy zinc-plated BBs and Crosman Copperhead BBs for velocity with the HK MP5 K-PDW. You might think that all BBs are alike, but my testing experience over the years has proven otherwise. In this test, Daisy zinc-plated BBs averaged 430 f.p.s., with a range from 424 to 438 f.p.s. Crosman Copperhead BBs averaged 435 f.p.s., with a range from 427 to 446 f.p.s.

So the Daisy spread was tighter, but Crosman BBs went slightly faster. What will that do to their respective accuracy? We won’t know until we test them both, of course, but I would expect the BBs with the tighter spread to group closer together. However, we’re talking only a few fps difference.

Looking at the advertised velocity, I see that the results show a much greater potential than they advertised. I’m surprised to have gotten as many shots as I did at this elevated velocity, except that the longer barrel on this gun may have improved the gas management.

Magazine lockout
I discovered that at the end of the BBs in the magazine, the trigger locks up and will not function. It isn’t like the safety has been applied, either. When the safety goes on under normal operation, the trigger loses all contact with the firing mechanism and simply moves back and forth under the force of the trigger return spring. But, when the magazine is empty, the trigger is blocked from moving at all, whether the safety is off or on. It’s a nice feature for a fast-firing semiauto because you won’t waste any ammo.

I think you can forget about the blowback feature. It’s there, but there’s not enough reciprocating mass to feel the impulse. The gun simply pulses when it’s fired. I even turned it sideways so I could watch the ejection port cover move open when I shot. The action underneath this cover is silver, so you notice it in contrast to the black plastic of the cover itself. I could see it move, but was completely unable to feel any blowback action in the gun. I guess the good news is that a lot of gas isn’t wasted by this miniscule movement.

View…so far
Well, I like the light weight of this gun compared to the firearm. I don’t care for the non-HK rear sight, which puts a notch too close to the sighting eye. The regular HK rear aperture would have been the best way to go.

The power was surprising, especially in light of what’s advertised. You’ll want to be extra careful with this BB gun, as it has enough velocity to do damage at long ranges. And, of course, it needs to be said that you must watch out for ricochets, because this gun has the power to send them back at very high velocity.

The method of CO2 cartridge installation leaves me cold. It works and it isn’t hard to do, but it’s very clumsy. I would much prefer to just drop a cartridge into a hole and screw the cap tight than to remove the buttstock and have to assemble it every time a cartridge needs changing.

H&K MP5 K-PDW CO2-powered BB gun – Part 1

by B.B. Pelletier

Umarex HKMP5-K-PDW is a lightweight, handy BB-firing semiauto.

A real BB gun
At the SHOT Show this year, I was surprised in the Umarex booth by the appearance of a BB gun that looked for all the world like an airsoft automatic electric gun (AEG). One big clue that the HK MP5-K PDW is not an airsoft gun is the lack of an orange muzzle, which is required by law for all airsoft guns sold in the United States, but is not relevant to BB guns.

Let’s be clear about the definition of a BB gun right now. I am talking about a gun that shoots steel BBs — not the 6mm plastic balls that Asian manufacturers call BBs. Those guns are airsoft guns, not BB guns.

And this definition matters when unknowing parents and their children are buying and using these products, because it’s extremely dangerous to use a true BB gun like this one in a skirmish, where participants shoot at each other!

The MP5 K-PDW is a copy of Heckler & Koch’s 9mm machine pistol, or what is commonly referred to as a submachine gun. The “K” designator stands for kurtz kurz, which means short, in German. So, this model is a shortened version of the gun. And, there’s a civilian version of the MP5 that offers semiautomatic fire only. While it looks the same as a full-auto gun, there’s only one shot per trigger-pull. That’s what has been incorporated into this BB gun, as well. [Thanks to blog reader "HK," we've corrected the typo of the German word!]

Semiautomatic only
You cannot “spray and pray” with this BB gun like you can with a full-auto AEG airsoft gun. Instead, you shoot one shot each time the trigger is pulled. The letters PDW in the name mean Personal Defense Weapon, which connotes a legal-to-own semiautomatic version of a gun that’s normally restricted to licensed ownership, only. Actually, for U.S. use, the gun also must have a barrel that’s at least 16 inches long because it has a shoulder stock. That special model of the gun is designated the HK 94 and is not easy to find. The FBI also ordered a special semiautomatic variation of the MP5, which was labeled the MP5SFA2. SF stands for Single Fire, but of course their gun was not restricted to a 16-inch barrel and could be made in a more compact size. Single fire refers to semiautomatic fire, in which one pull of the trigger results in just one round being fired.

An MP5 firearm is a chunky beast that puts a lot of steel in your hands. It may be called a machine pistol, but it feels far more like a rifle when you actually hold one. And, since it shoots the mild 9x19mm Luger round, the recoil is not great. I’ve shot MP5s at legal machine-gun ranges several times, and they’re very easy to manage in the full-auto mode. Of course, a BB gun should also be easy to restrain, as well, only this one has a blowback feature, so there will be some movement when the gun is fired.

The stock swings out from the right side of the gun and locks solidly in place. The pull of the extended stock is a reasonable 13.5 inches, but the rear sight notch is positioned too close to your sighting eye, which will make precision sighting difficult. I have to pull my neck back to allow a few extra inches so I can even see the rear notch. I like the H&K aperture rear sight better, for this reason. The rear sight is a drum with multiple notches around its top, but it cannot be adjusted in either direction. The front sight is a simple post inside a narrow globe and it also does not adjust.

The rear sight is a notch, but should be an aperture when located this close to the eye. It doesn’t adjust.

This BB-shooting version weighs just over one-third what the firearm weighs, so it’s light and manageable. The bulk of this gun is rugged plastic, with metal parts used where necessary. That make it light. Since I haven’t fired it yet, I can’t comment on how the blowback feels; but as light as the gun is, I’m expecting to feel some realistic movement.

The curved magazine holds up to 40 BBs, which is only 10 more rounds than the firearm carries. So, the loading interval should be very realistic. I remember when I was shooting the firearm how sore my thumbs became from loading the mags and how quickly the cartridges were consumed by full-auto fire.

Installing a CO2 cartridge
To install and remove a CO2 cartridge, the stock must be pulled off the gun. The owner’s manual is of very little help in this procedure, as it refers you to a tiny photo showing two black plastic stock pins with red circles around them. I have made several larger photos of the pins and will give you more detailed instructions.

First, unscrew the piercing pin screw all the way. Then, remove the buttstock by removing the two plastic stock retaining pins.

The manual clearly says to use a plastic pin punch to remove the pins, though there are no pin punches included with the gun. However, I discovered that the back of a Bic pen will do the job perfectly. Just push the back of the pen down on top of each pin, and the retaining wires will be pushed out of the way. The pins can then be pulled out on the left side of the receiver. They’re captive and do not have to be completely removed from the receiver for the stock to be removed.

Both stock pins must be removed to pull the stock for installing a fresh CO2 cartridge. Each pin has a wire retainer in its center that holds it in place. The shape of the wire allows it to move out of the way when pressure is put on the end of the pin.

There’s a pin at the top of the stock fixture and one at the bottom. Both must be pushed out to the left side of the receiver.

You don’t need a special tool to remove the stock pins. Just press in on them with the end of a pen and they push out easily.

The stock pins are captive and do not have to come all the way out of the receiver.

Once the pins are out of the way, the stock comes off like this. Then, the CO2 cartridge can be installed and the stock replaced.

To get the pins pushed back in the gun, you may have to tap them with a plastic mallet or a piece of wood. The wire retainers need to be coaxed back into the center of the pins before they’ll enter their respective holes in the stock.

While this sounds like a drawn-out procedure, it takes longer to explain than to actually do it. After the first time, you’ll be replacing cartridges in less than a minute.

Many of the switches and controls are either cast solidly into the plastic body of the gun or are dummies. The cartridge follower that’s located on the front left of the receiver, for example, is a spring-loaded steel part that moves in its track and can be locked in the rear position but has no real function to serve.

The two-position selector switch can be set to either fire or safe. On safe, the trigger is disconnected from everything and just moves in an arc. When the switch is set to fire, the hammer is cocked and released with every shot.

Two settings: Fire and Safe. Fire is semiauto, only.

We’ll look at velocity and shot count next. I’ll chronograph the gun with both Daisy and Crosman BBs to see if there’s a preference.

Parents, this is a BB gun that shoots steel BBs. Do not mistake it for an airsoft gun. It is not meant to serve as a skirmish gun, where players shoot at one another. The velocity of this BB gun coupled with its small steel ball projectile (the BB) makes it very dangerous. It should never be fired at a person or animal for any reason. Also, steel BBs can rebound from hard surfaces with great velocity.
