I bought an AS46 mag but darned if it will work in my Derya MK12. I even changed followers thinking that would be the answer but the round seems to angle up and jam before it can enter the chamber? It's a mystery because the mags appear identical. It fits in and locks but won't feed properly. Funny thing though I put the AS46 follower into the Derya 2 round mag when I switched followers and up at the range Tuesday I loaded it with 2 rounds and it cycled just fine.
Is this a Lockhart or original Uzkon? I am sorry it isn't running for you. You are the first I hear of that is having this trouble. Me and several others I know are running them in Derya Mk12 and Typhoon F12 shotguns without trouble.
