[QUOTE="uncle money bags, post: 2386386, member: 8377"] We need pics dude. Im betting the groves are caused by burs in the barrel extension cuts. Also, does this problem occur with several different mags? What mags and followers are you using? A picture from the chamber end will help, but it wont necessarily determine the cause. We will be particularly interested in a close up of where the barrel extension meets the upper at the 5-7 o'clock area. Aestus, did you mean you cut the m4 feedramps into the barrel extension since the m4 uppers already have the ramps cut? Only asking so those who dont know the difference are not confused. [/QUOTE]
