Got several of locally made 40, 30 and 35 rounders today. Anti-tilt followers, lips with hardened steel inserts and the polymer feel and finish looks nice. For less than GBP 15 each they're a steal :) A range report will follow soon.
Chuck, as I use my rifle only for IPSC competitions I usually shoot on the move. For prone shooting I use a Pmag20.
BamBam, I doubt that Bulgarian army will have the funds to change the AK rifle in the following couple of years. Thanks a lot for the Troy mags, I'll send you a PM. :)
