Umarex M3 Grease Gun Reviews

The looks, feel and operation are realistic.

The gun would fire several shots then stop. I found that the second CO2 cylinder wasn’t punctured by the end plug. I added a thick washer between the two cylinders and the gun operates perfectly.

Buy large quantities of BBs and CO2 cylinders.

Very accurate presentation. Similar in size and weight. Some deviations that are necessary and don't detract from the whole. Shoots well. Goes through 60 BB's very fast.

There is a problem piercing both cartridges (using Crossman). Solved the problem by dropping a steel washer on to the base of top cartridge.

PRICE!!!!!

I would win the lottery so I could afford the real thing.

This is a beautiful rendition of the original M3 Grease Gun that my Dad carried as a Forward Observer in Korea. I have a picture of him carrying it, standing next to my Uncle Forrie, who had picked up with their artillery unit. So Dad would sneak around and find the bad guys and call his brother to tell him where to shoot!!!! Great reason to buy a gun, not that I ever needed one!!!! I may never fire this piece, but is an incredible sub for the real thing without the price of a divorce!!!!! Oh, I have the M14 replica too. My buddy, a Viet Nam Veteran, wouldn't touch it at first, thought it was the real thing. N'uff said!!!

Really an accurate replica! Both of my sons have replicas of the M1 Carbine. You are a super company !

Nothing

looks just like the real version. The full auto is insanely fun!!! shoots very accurate. You cannot cans over like they are nothing!!!

not one thing i would change on this gun it’s super fun and very realistic

Buy a lot of CO2 and BBs cause you’re gonna be out there having fun all day!!!

Shipping was fast

Get one that functioned properly

Outer CO2 cartridge would not puncture. Had to send it back

There are many machine guns of various kinds, and we all have our favorites. Might be the M2, M1919, M60, whatever, but I have always coveted the M3. I have books, engineering drawings, everything about them I am fairly knowledgeable on. I had hoped to build one from scratch, but this is a more fun and legal way to enjoy it. This is a very nice reproduction of the real thing, and it is just a pure blast to shoot. The shoulder stock has a solid fell just like the real one with good solid lockup when you pull it out. I found the peep sight to be surprisingly accurate, put my first single shot BB in the 10 ring at 25 feet. But then I went full auto and shredded the target. I got the package deal from Pyramyd, plus their 20% off coupon, and they shipped it quickly. I was burning through BB's at a budget busting rate in just a couple days. Buy from Pyramyd and get good customer service and support a small business.

Nothing really, but a more sane rate of fire like the real M3 would be cool.

It is fairly easy to load the mags from the pour spout of some BB containers, I bought the Umarex speed loader, but it has issues. Iit seems to have a design flaw that keeps it from operating smoothly in manner that gets the BB's into the magazine without spilling them, or sometimes blasting a whole bunch all over the place. Most times the plunger locks up and you have to tap the unit to get it to work. My son had one and I knew it was not very good, but thought his was defective, it was not, then again, there are times where you get several plunger operations and it loads 5 or 6 BB's each time perfectly. There must be a technique to it. Some discussion has been made about the trigger pull, it is a bit tight, but in the heat of fun, you won't notice it. Be careful, these guns are addictive, I already want the Thompson.

About as much fun as you can get for the money. Everyone I've showed it to wants one before they even shoot it.

It's a bit of a CO2 hog but every gun I have that uses two cartridges at once is that way.

Order it. :)

Historically, accurate, same weight as the real gun

Only one CO2 cartridge is pierced. Find some way to alleviate the problem.

You can put two CO2 cartridges in the magazine, but only one will pierce best way to alleviate problem put a dime between the two CO2 cartridges

Awesome, so very cool. The 12-year-old locked inside me came out to play. Other people look at you like "WTF"

A faux silencer would be great and would capitalize on the already existing low sound signature

Chambered very poorly with the Dustbuster BBs. They simply squash or get stuck in the barrel due to their construction. Stick with steel or copper

Fun to shoot

Sling added would be nice

Won't work without ammo in it

I love the full auto function. Works great.

I would include a sling. This thing is pretty heavy.

I’ve had problems getting both cartridges to puncture. Switched to Umerex cartridges without success.

Well built. Looks fantastic. A ton of fun to shoot. Cans and targets are fun, but chasing a pesty rodent is gut hurting laughter! It's not to loud, and actually has kind of a cool harmonic ring to it when shooting. It's heavy. I like that. I'm tired of paying good money for cheap plastic janky feeling air pistols and rifles. I'm mainly a PCP purist, but this thing has me giggling every time I load a magazine.

Get rid of the plastic barrel and use metal. If you remove the barrel shroud, you can see that the barrel is a plastic tube. Maybe it's some special super durable plastic, but it just seems janky to have a plastic barrel on something that is almost all metal. Tighter quality control for the piercing plug. Too many people with the same issue. (And NO, I'm not willing to buy more expensive CO2 carts just to remedy their problem) This thing is made to eat CO2. At least send 1 replacement green O-ring for the plug. It's going to wear out.

Find something to do with the used CO2 carts. You will have a lot of them. LOL! I also had the problem with the CO2 not piercing from the screw in piercing plug. Simple fix. Fine wet/sand paper on a granite counter top. Sand the face of the plug/piercing thing in a circular motion with light pressure. It takes off enough material so the plug can seat deeper and you get a solid pierce of the CO2. Done, simple, quick fix to a problem many have had. The BBs in the magazine must be in the staggered position or they do not feed properly. They get jammed up. The only time my mag doesn't feed is if the bbs are not staggered properly. Still figuring out a way to load the mag quicker with them all staggering correctly.

+Realistic weight

-Heavy (not a huge downside) -Does not like any ammo other than Daisy bbs. Not even other brand steel/zinc bbs work.

Very picky full auto replica that's fun to use. Not my favorite replica but still worth getting if you like the grease gun. Just know it only likes Daisy brand zinc/steel BB's. Can get about 2 mags until Co2 depleted.

Full auto fun without the Class 3 hassle and 200 dollar transfer tax but stamp! Weighs as much but as the original,extremely accurate copy.

Nothing

Magazine was a bit sticky at first but soon became corrected with use

just a hoot to play with. I mean serious hoot.

make it 22lr, but then it'd be a pain to own...

Cannot be used to grease the front end on your F150

Overall, this M3 is built tough....Imagine carrying this thing on a battlefield every day and night....It is very built and sturdy as are the magazines....No jams as, good quality, BB's flow perfect....Make sure the CO2 plug is seated tight, donot over tighten, to pierce both cartridges....

Nothing....It is perfect the way it is....

This is a heavy gun so younger shooters may have a problem holding and controlling it...No rails to mount extras sch as red dot, lights or scope... The M3 is not made for any additions...All you need is the gun, spare mags, oil, CO2 and you ready to go....Remember, as with all firearms including air guns, accuracy comes with practice, practice and more practice... The M3 is not made to be accurate...It's made for full automatic fun....Also, remember to lubricate....My rule of thumb is with all my collection, "if it moves, oil it"....

looks, weight

The trigger guard edge is very sharp and not comfortable to the hand, it should been a little thicker with rounded edges. It is a stamped sheet metal gun so you have to accept sharp edges.

Gun is hard to sight in and you really have to crank in the magazine plug to get both co2's to pierce, almost needs to be torqued. Also it is not easy to get the bb's to stagger stack right in the magazine

how it looks like the real one

nothing

I like the weight and feel and look of the gun. Very nice even if you just use it as a wall hanger in your Man Cave. I will shoot mine and enjoy it. Some how I ordered two of them but I will keep both. I also have an extra mag for them and will order another..

I did unscrew the barrel and the real barrel inside seems to be made of a polimer plastic. It seems to me for the price of this thing it should be made of a metal. Also for the price it should come with a leather sling. Although I read where a M1 carbine sling will work and it also looks like a SKS dog collar sling will work. But for the price.. come on include one with the gun.

Its pricey but buy one if you can and enjoy it as a wall hanger or a shooter or both.
