AK74 shot with VEPR 12

The year is over and before we clean the saiga we decided to knock off some of the using a shotgun.. we used bird shot at a distance of 25 yards.. I wasnt sure on what kind of damage would be done to the 74 so I used winchester bulk box. I attribute the one fte with the vepr on the ammo, not the firearm... That was the only malfunction i had all day and of course it happened during this test..
