Nothing custom about it. Its just a WASR Romanian AK that you can buy pretty much the same way for about 295-314 if you shop around.
I bought a few M44 nagants off them when they were giving them away for 69 with shipping. They take forever to ship and their gusn are ntohing more than stock guns with a black painted finish instead of plain parkerizing.
those are just """"sporterized""""whatever--- WASR rifles. lol... the top one sells for 309 at AIM thats about 40 less and AIM is good to deal with. Better route, & the stock u like sells for 10 bucks on gunbroker.
Definitely just WASR Romanian AK's. Low quality AK's but definitely the nicest parts I've seen on one. I have a GPWASR10 and it functions reliably. Nowhere as nice as my Arsenal AK74 but still a perfectly reliable rifle.
With an AK as long as the metal in the parts is good its all just in the fit and finish for the most part. 300 gets you a meat and potatoes AK and 600 gets you the same thing pretty much only more refined.
