Does not matter ifs under gas pressure or being manually charged. GI buffer spring H1 buffer. Even when its being operated manually, empty (no round) it still seems reel tight going into lock. When it does fire the empty case seems to get caught in the upper, sometimes it just wont extact, and tries to jam a loaded round into a empty case. About the only thing is hasnt done is double feed.
