From what the sign in the first picture says, it looks like the Vepr-12 will fire 2.5 and 2.75 inch 12 guage shells, have a capacity of 5 shells of the 2.75" length and 8 shells of the 2.5" length, weigh in at ~9.25 lbs. (4.2 kg) and have barrel lengths of 21.25" and 26.75". The weight would sure make for gentle recoil.
thats just the swat version of the Saiga 12. The 1968 gun control act (sporting purposes clause) will not allow that gun to be imported into the U.S. also the 89 import ban. Oh well I would love to own that gun too.
