Shotgun Build 2: No Limit Scattergun

For USPSA, I love Open because I think it’s cool. If I’m gonna shoot a racegun, I want the fastest, blastiest racegun. I don’t want a bunch of rules about what I can’t do. Plus, electro-optical sights are cool, and loud compensators are also cool.

In 3-Gun, Open Shotguns are even better. Not only do they get cool red dot sights and cool compensators to spit fire, but they have a whole bunch of nonstandard magazine designs open to them. One such idea is the X-Rail, which is a cluster of four magazine extensions in a rotary unit, kind of like a giant revolver. Each holds six shells, so you get 24 out on the front. It’s super heavy, but you won’t have to reload as much. Empty gun starts still suck.

On the one hand, the X-Rail lets you use highly reliable, proven shotguns, like Benelli M2s. On the other hand, that’s a lot of weight on the end, and I’m not a big fan of super heavy weapons. Especially when the weight is out on the end of the gun. So that’s out. Pretty arbitrarily, but I don’t care. This is my list.

I want a shotgun that feeds from detachable box magazines. Shotgun shells make these difficult to make, and for some stupid reason, no company in America makes any sort of base gun that we can work with. Which leaves us the choice of Russian Saiga 12s, Russian Vepr 12s, Turkish MKA-1919s, or Turkish XTR-12s.

And no, those aren’t staying stock. Once again, I’m going to order a tricked out one, mostly because I don’t have the expertise to do that myself. Plus, some of the things commonly done to a race shotgun aren’t things I can do myself.

The other complication is the bans on imports of Russian weapons, which could distort prices when I finally go to purchase. That said, there are a lot of imported guns. And, unlike my pump gun, this was never going to get done on the cheap. This shouldn’t disqualify the Russian-made guns out of the gate, especially because I can still get base models for a reasonable price on Gunbroker.

Right out of the gate, we can eliminate the Saiga 12s, because the Veprs do everything the Saigas do, except way better. The Vepr comes in a not-stupid configuration out of the box. The Vepr doesn’t need tuning to actually work out of the box. The Vepr has a much more consistent build quality.

We can also eliminate the XTR-12 pretty quick. At the time of writing (October 2017) there are issues with getting large-capacity magazines to work reliably. And that’s the whole freaking point of open shotguns. There’s also very poor aftermarket support for these.

Two down. Now, the MKA-1919 actually comes in a couple different versions. One is from Tooth and Nail, and comes heavily tricked out. The other is from Firebird precision, and they remake most of the components right here in America. So, better tolerances, and hopefully better reliability. However, they don’t offer a compensator option. The T&N MKA 1919 build is available with a mid-barrel compensator. So, at this point I’m inclined to only look at the T&N one, given the better configuration options.

Vepr-12s from Dissident Arms also come with nice big compensator options. They use compensators at the end of the barrel rather than midbarrel ones. On the one hand, the Vepr-12 will have some increased costs from requiring a charging handle conversion (i.e putting a charging handle on the left side of the receiver).1 On the other hand, the Vepr-12 is probably the most reliable. It’s certainly the most reliable out of the box. In fact, it’s one of the few detachable box fed magazine shotguns to function reasonably out of the box. Points in its favor.

The other item in the room is ‘classic Russian Ergonomics’. Which we can improve somewhat. We can get a safety that’s workable with the shooting hand thumb or trigger finger without removing our shooting hand from its place. As mentioned before, we can put the charging handle on the correct side of the gun with a simple modification. We can also get a modification to be able to drop the magazines with our trigger finger. On the other hand, the MKA 1919 has AR-style controls. Well, other than the charging handle placement. It is at least on the proper side out of the box.

Now, to my way of thinking, that’s about a wash. Competitively equipped models are about the same price. However, the Vepr-12 has one other edge over the MKA 1919: I live near, and have squadded with, a member of the Dissident Arms shooting team, and he’s pretty active on youtube as well. So there’s a nearby Vepr-12 expert that I know.

And there you have it. My pick is the Vepr-12, tricked out into awesomeness by Dissident Arms.


  1. Someone2 might chime in that the normal charging handle on the right side. This is true and completely irrelevant. Open guns are made to fit you not the other way around. Also, if you want competition guns on the cheap, you’ve got the wrong division.
