Well, since a Czech pistol really isn't a way to celebrate Mikhail Kalashnikov's birthday; I got this Polish AKMS underfolder this morning.
The good news is that it is not a Century build,it was built on a Ewbanks Mfg EMAKM receiver. Other good news is that it is matching (bolt, front trunnion, dust cover and gas tube), has nice furniture on it and a TAPCO G2 trigger.
The downside is that when I got it, it had a Romanian pistol grip, the muzzle brake was scratched up and looked aftermarket ,and the cleaning rod isn't stock (it extended to just outside the slant brake). Also, there is some wobble in the underfolder stock, at least more than my M70AB2 (which is pretty tight).
So I put on a Polish grip I had in my parts bin, as well as a better muzzle brake. I also put a Polish lower handguard I had just to see how it looked, but the upper handguard around the gas tube was on so tight I couldn't get it removed. So in the above pic it shows the replacement lower handguard and the original upper. I also attached a Polish AK bayonet and a green canvas sling I had.
Overall it's a nice AK, and for $400 I can't complain!
Cheers! M2
