[QUOTE="Not Jobless, post: 1503041, member: 16000"] Internal blow back of gasses is huge, it makes a substantial mess. After about 400-500 rounds or so it starts to impair the operation. It took me 4+ hours to clean :beer: All that blowback wants to go "somewhere", and as it's looking for places to go it finds the bolt catch which is designed just right to tunnel gasses and force it's operation thus locking the bolt back at times prematurely. This was fixed with a dremel tool and some slight grindind forward of the bolt catch lever on the mating surface of the lower receiver. Works pretty much flawlessly now. [/QUOTE]
