Neat! Is there a muzzle brake on it? What thickness of armor could this pierce?
It'd say something about 25mm at 200-300 meters. It could easily penetrate APC's such as BMP or BTR. I shot the thing at an old BTR (don't remember which model it was). Rounds were getting through side armor and set old crap that was inside on fire. It'll probably go in and out through something like a HUMVEE, Ukrainian army has lots of those now. It renders non armored vehicle useless with one shot if engine is hit. Like I said before, now rifles get scopes and have way better chances of hitting a target than during WW2. AP incendiary rounds are pretty nasty and can take out lightly armored vehicle no problem. 3-4 rounds go in and you have a fire inside.
