I'm on a bit of a Mak kick lately. Picked up a Bulgarian milsurp and a Russian IMEZ commercial Mak. 500 rounds through the Bulgie and 150 through the Russian with no problems. I shoot nothing but Brown Bear and these things just digest ammo. The accuracy reputation these guns have is very well founded as well. Some pics: Both guns with a mix of mags inc. 2 E. German mags: Bulgarian: Russian : 3 shot group with the Russian I made today at 15 yrs offhand, the Bulgarian will do the same with its fixed sights. Overall I like the Bulgarian a bit better, I have the thumbshelf grips on her and she just feels a bit "smoother" overall. I love these simple, durable little beaters.
