Hi, im new here this is my first post and im thinking of getting my first AK. I visited atlantic firearms and the RJ polish underfolder really caught my eye, i was wondering what you guys think about it overall? Also what can you guys tell me about the american made barrel and reciever? Iv seen a few videos of aks blowing up because the reciever couldnt take rapid fire it looked like. Is that why the US requires american recievers? So we cant rapid fire or bump fire or whatever? Im guessing the do this so we dont convert to full auto. Let me know what you guys think, theres also a review on youtube.
