"National Match" MAK91, as pictured. 18" barrel (~2" longer than the MAK90), milled receiver, should be an angle-cut rear under the stock. Good shooters but not easy to upgrade, they have a good amount of value if you decide to sell.
Don't see many Chicom AKs here in Astan. This one is a Type 56 produced by factory 416. Stock and PG has been replaced. SN on receiver, op rod and recoil rod. No muzzle nut or flash hinder on muzzle thread. Cleaning rod was a locally produced rod. Gun headspaces and function fired on semi and auto.
