Really? This is about a real gun, not a video game gun.
Anyway, that is the craziest thing I’ve ever witnessed someone trying to do, and that includes the “pirate pistol” sawed off shotgun I’ve seen. There’s really no practical reason to make something like that.
If you do that, I think you are supposed to have the $200 Short Barrel Rifle stamp. Maybe if you chop the stock first you are OK. The ATF doesn’t write tickets.
While the M-N makes a fine hunting rifle, I don’t think this thing would be useful for hunting anything other than zombies. I love my M1944 Carbine, and it’s got a kick like a mule: I can’t imagine trying to keep it steady without a shoulder brace.
Historically, obrez shooters pulled the bullets from 7.62 x 54 R cartridges and removed some of the powder before putting the cartridges back together for use. It’s a simple enough process. Alternatively, if you are into reloading, you can quite easily cook up a reduced charge load of your own.
In use, the obrez was a very close range weapon. I believe I’d prefer a TT-33 pistol or even a Nagant revolver over an obrez, but if all I had was the obrez I’d feel pretty far from unarmed.
We’re talking about dumping half of the powder charge. The obrez wasn’t the most fun-to-fire piece ever, and a substantial reduction in powder charge is necessary to keep it from flying out of your grasp when triggered. Even a half-charge 7.62 x 54 cartridge is more than stout enough to put a hole clear through somebody (along lots of powder burns) at typical obrez ranges.
FWIW, my wife’s family (native Ukranians) find the obrez fascinating as a “gangster gun” much the same way people used to think of the Tommy gun here in the US.
Interesting trivia: Obrez is apparently a generic term. Further conversation with my wife and her family indicates that any cut down long gun is termed an obrez, not just a shortened Mosin Nagant. She showed me a video on an Eastern European youtube type of site that was called (rough translation) “shooting an obrez.” It was a couple 20-something guys fooling around with a sawed-off double barrel shotgun. It looked like it was probably a 12 gauge.
Obrež is a village in Serbia according to Google, perhaps “Obrez” as a term for a weapon is along the lines of a “Chicago Typewriter”, a joking colloquial term for a fearsome weapon.
