223 just wasn't meant for this rifle, there's just something wrong about that... and the rifle knows it. stick to 762 and be jolly.
They haven't redesigned the gun for the caliber...
if they insist it is fine ,I wonder how they would feel about a charge back on your credit card ?
Lol I wont even feed this. But yeah it was designed for 7.62x39 and it should stayed like that..
what ammo is that ? mine is very picky on that. winchester white box works best.
the firing pin is the problem, its too weak.
had the same result with MFS ammo, strike the primer but no boom.
