Our favorite guest blogger, Vince, is at it again. Today, he shares his experience of testing a Chinese airgun.

Now, take it away, Vince!

Ahhh… the way we were! The way some of us were, anyway. By “us,” I’m referring to those of us who first got into airguns (or came back to airguns) after being seduced by those irrascible Chinese. I’m going back about, oh, 10 years or so ago, when, waltzing through the internet, we would find all sorts of places selling “The Chinese Can Opener” or the “High-Power Military Training Air Rifle.” What a deal they were — my goodness, why on earth would ANYONE spend $100 or more on one of those high-falutin’ overpriced airguns when these $25 Chinese models were obviously just as good? And we knew they were just as good because that number said so!

You know, that number. The velocity number. Because that was the only thing that mattered! That one number told us the whole story!

Sooner or later, we discovered the inevitable — although for some (like, uh, me), it was certainly later than sooner. Eventually, the B3, B4-2 and Fast Deer airguns went by the wayside to be replaced by Gamos, RWSs, Cometas, Noricas, and then Spanish and German Beemans. Around this time, the Chinese started cranking up the quality, though, so their better products didn’t entirely leave our field of view. But the old carved-out-of-a-2×4-and-lubed-with-pig-fat models — along with all their broken seals, mainsprings and promises — were pretty much forgotten.

But man is a funny animal, and a collector (even a half-baked collector) often sees value in diversity as well as quality. And just as a man who collects Mustangs sort of really needs a 1974 Mustang II 4 cylinder automatic (as horrid a car as it was) in his collection, I began pining for some of those old, crude guns just because they were there.

So it was that I found myself fishing around for some of those old bottom-feeders…those poorly made, all wood-steel-and-leather guns that smelled like bacon grease when fired. Those guns that, frankly, I had virtually no interest in shooting, except to appreciate the better guns that came later. The subject of this report, the Industry Brand QB-51, is one of those fossils I dug up.


Industry Brand B-7 spring-piston rifle.

This .177-caliber breakbarrel air rifle was also called the Industry Brand B-7 and shouldn’t be confused with the BAM B-7. That gun was the old sporter-style sidelever that actually had a reputation for being sort of decent. No, the Industry Brand B-7 was one of those smoke-and-soot, machined with a dull file and worn-out drill bits and carved-with-a-hatchet examples of communism at its most typical. If you were lucky, it worked out of the box. If not, well, it simply didn’t. But luck shines upon me, and this one actually did.

The QB-51 was one of those novelty guns they used to put together by combining a low-buck action with some possibly less-than-useless useless bells and whistles. This one was apparently playing paratrooper with a folding wire stock, a total weight of under 6 lbs. and an overall length of only 35 inches. But it’s not a kid’s gun by any stretch — the pull length of 14 inches and a 28-lb. cocking force certainly attest to that.

Since the folding stock is obviously the most interesting aspect of this gun, let’s take a look at that first. It actually has two interesting features, the less obvious being an adjustable buttpad.


Buttpad is centered.


Buttpad adjusted down.

Is an adjustable buttpad on this cheap gun completely pointless? Actually it isn’t. It can be used to dial up a more comfortable shooting position. The gun does look awkward as all get out if the pad is moved too far off the normal position; but let’s face it, this pup isn’t winning any beauty contests if the judges are permitted to keep their eyes open.

The folding stock is perhaps less useful.


Folding stock extended.


The stock is folded flat against the side of the gun.


This is what it looks like from the side.

Some rifles with a folding stock can be handled as a pistol (sort of); that’s not really going to happen with this gun. All it does is make the rifle a bit shorter and easier to pack up for transport — if you could think of any reason you’d want to. But at least the rough cast folding/locking mechanism is stout enough.


The hinge is stout and tight!

Moving past that, we come to the pistol grip — and another gadget! The grip is hollow and has a sliding door at the bottom.


The grip has a secret compartment!

Presumably, you can put pellets in there. It would hold several hundred, even if getting them out one at a time might be a bit tricky. Again, we have an oddball feature that still isn’t quite useless.

On top of the gun, we can see the simple rear sight. If you were into mid-grade airguns 10-15 years ago, you might recognize it. This is pretty much a knock-off of the old Gamo sight that used to come on a variety of their breakbarrels. Frankly, they did well to copy it. It’s simple, largely devoid of free-play and pretty darned rugged.


The rear sight was kind of nice!

Finding it on this rifle was a pleasant surprise, and I was hoping to find a similar surprise as I moved rearward toward the trigger. I already knew that Industry Brand used a knock-off of the Gamo trigger in their QB-57, QB-88 and QB-25 models. When I saw that telltale safety tang in the triggerguard area, I got my hopes up. It says something about bottom-feeder Industry Brand triggers when you’re seriously looking forward to a Gamo trigger. But even those modest hopes were quickly dashed. This gun has a simple direct-sear and a crude sliding safety, both of which makes a 2004 Gamo Shadow feel like a Swiss watch.

As I move around the gun, it’s becoming obvious that this thing is based on the old Industry Brand 61 and 62 model actions, later known as the B-1 and B-2, respectively. I’ve had those. My B-1 had a horribly inaccurate barrel and probably a 12-lb. trigger. One B-2 had a soft trigger that quickly wore and went into the auto-fire mode, and the other B-2 bent its rear retaining pin because it couldn’t handle the spring pressure. As one might guess, I don’t get all excited by B-1/B-2 variants.

One giveaway is the breech pivot bolt.


The pivot bolt has only four places for the locking screw to engage. That often makes it difficult to adjust properly, for many times you want to stop somewhere in-between.

And the other is the smashed-leather breech seal.


The leather breech seal is as flat as a pancake.

Both are hallmarks of Industry Brand inferiority, and that breech bolt (with its four positive locking stops) frequently makes it impossible to properly tighten up the sideplay without making custom washers to go under the bolt head.

Oh well…let’s keep going. The front sight is basic enough.


Front sight is what you would expect.

Although I won’t be using it. I’ve learned from recent testing that I just can’t be consistent with open sights anymore — so I pretty much have to go to a scope. The problem is that the grooves milled into the receiver are ridiculously short. In trying to mount a scope, look at what I had to resort to.


The Daisy variable scope was cheap enough and worked well. Notice how close the rings have to be to fit the short dovetails!

The skinny scope mounts I used — moved as close together as possible — barely fit. The scope, by the way, is a cheap Daisy Powerline 3-9×32 (no AO), in which I had fudged the objective lens to eliminate parallax at 10 yards. Set up this way, the $35 scope works like a champ — and seems way too good for a rifle like this.

I do have some concerns about running a scope on this gun, however — Diana’s aren’t the only breakbarrels to have droop, and this one seemed to have joined that party. But there’s only one way to find out, so I’m off to test it. And, yes, this time I checked the stock screws first.

I’m shooting the gun with the same series of pellets I used last time — although, frankly, putting Crosman Premiers through this rifle seems rather silly.


I tried all these pellets in this gun.

No matter, same drill — 5 shots to get the barrel used to a pellet, then 5 on each through two separate bulls.

Much to my surprise, dialing in the Daisy scope wasn’t such a big deal, and soon I was landing pellets close enough for government work. Though the Daisy scope worked well enough, the Daisy Precision Max wadcutter pellets didn’t.


Daisy Precision Max wadcutters: These shots are hard to see, but the group sizes are listed next to them.

These groups came in at 0.66 inches and 0.82 inches; but come to think of it, maybe I’m being too hard on these pellets. Maybe this really is the best this gun can do!

Crosman Competition wadcutters do nothing to dispel that notion. At 0.78 inches and 1.40 inches, they’re making the Daisys look good.


Crosman Competition wadcutters.

At 1.28 inches and 1.52 inches, Crosman Hunting pellets (pointed) do even worse.


Crosman Hunting pellets.

Even my cherished Crosman Premier hollowpoints are sucking canal water at 1.12 inches and 0.9 inches.


Crosman Premier hollowpoints.

Of all the Crosman pellets, only the Premier Lites seems to consistently do under an inch — although 0.82 inches and 0.9 inches is nothing to squawk about.


Crosman Premier Lites did better, but still not great.

Oddly enough, those new Gamo Match pellets I don’t like so much just about equalled the Crosman Premier Lites in this gun.


Gamo Match pellets were a pleasant surprise. But it still isn’t good enough.

But at 0.95 inches and 0.88 inches, they still couldn’t match the Daisys. I had high hopes for the RWS Diabolo Basic pellets that seem to shoot so well in many low-power guns. I finally started to see some improvement.


RWS Diabolog Basic pellets are an inexpensive wadcutter. They look good here.

At 0.57 inches for both groups, they were quite consistent; and now we’re starting to get into the range of acceptable performance for a cheap rifle.

But then we have the Beemans. Not the German Beemans from H&N. I’m referring to those imposter, Chinese-made Beeman wadcutter coated pellets. My very first group with them was typical for this rifle.


These groups are difficult to see, but Beeman coated wadcutters, which are made in China, did remarkably well.

As you can see, the second group was a shocker. We went from 0.78 inches to 0.37 inches in one set. Something’s up. Let’s try this one more time.


Incredible! Almost a quarter-inch group of Beeman coated wadcutters. I circled the group for you.

My goodness! Stick a feather on my rump and call me a turkey — but this Chinese junk just put 5 pellets into virtually a 1/4-inch group.

Now, before anyone starts complaining — “That’s not fair! No other pellet got a third chance!” — let me explain something. The Beemans were absolutely the first pellets I shot, and during that time I was trying to come to grips with that yucky trigger. That’s why I think the first group was poor. Since the second group did so well, I shot the third group last after I had completed all other testing. So I think this third test was fair and that it really means something.

[Editor’s note. This happens sometimes, and it’s a reminder of the hold sensitivity issue and why things have to be done just right to see good results. I’ve seen what Vince is talking about. With some experience under your belt, you’ll know when something deserves a second chance like this.]

But before we get too excited, let’s do a velocity check. Since the Chinese Beeman pellets were far and away the best, those were the only ones I tested. 10 shots came out like so: 396, 397, 388, 390, 380, 381, 381, 379, 381, 377.

We immediately notice three things: (1) The velocity stinks, especially for a gun with an almost 30-lb. cocking force. (2) The velocity seems to be on a downward trend. (3) The spread of 19 f.p.s. is significant, considering the fact that this thing is outgunned by a P17 pistol.

Where does that leave us?

Well, to begin with, this gun obviously has a decent barrel. Not sure how that happened, but happen it did. And if the barrel is good, the gun is good, right? Couple that with the fact that, against all odds, this example also seems to have a consistent lockup — and we seem to have a perfect diamond in the rough.

Yes — very rough. I could probably go through this gun and get the velocity up to 500-600 f.p.s. range, and some trigger smoothing and lubing would probably help as well. Even at that — will I ever want to shoot this thing just for fun? Really?

If I’m honest — not really. In fact, I have absolutely no reason IN THE WORLD to go through the trouble of tearing this thing apart and making it right.

Nope. No reason at all.

I’ll let y’all know how it turns out.

[Editor’s note. Maybe I should have made this a Part 1. We’ll see what Vince does. I don’t want him to feel pressured.]
