Well, yours was actually broken according to you..
I dont see the point of FAs on ARs either. I ain't slamming something home that doesnt go naturally. In your case it wasnt the chamber or cartridge, but a broken rifle.
I heard the AK63DS barrels were soft...but i also feel like that's splitting hairs. Dont yse it as a pry bar or do multiple FA mags dumps and itll be fine
I sometimes wonder if all my waffles are really worth it. I could buy an entire rifle for what I have in waffles...or enough ammo to last me a lifetime at my level of shooting.
