on the m4 jam i dont think im short stroking the m4 with novenski brake is a shorter barrel i had it tig welded to be legal it runs fine i say 98 percent of the time when i have this jam it looks like the bolt is right behind the round the stripping it but it jamed right below the feed ramp it does not havee m4 extenion or m4 ramps if it did i dont think it would happen

triaxle, first u need to use a goddamn period or two! you're killing our eyes here!

OK, secondly look closely at how your barrel extension and your upper match. you describe the malfunction from one side of the mag, so look at that part of the extension/upper closely. is this the area where the bullet tip gets caught? who made the upper and barrel? let us know and use a period!
