[QUOTE="nksmfamjp, post: 2707246, member: 1951"] So, it doesn’t “fully cycle”?? Does the bolt move rearward at all? Does the empty extract and eject? Where does it eject to? Does the bolt pick up the next round? Does it stop just short of chambering? Basically a DI gun gets gas pressure through the port. It unlocks the bolt. Remaining port pressure….or actually the inertia from the opening burst of pressure moves the bolt carrier assy and buffer to the rear. It needs to go far enough to the rear to eject and allow the mag spring to push the next round to the feed lips. Then going the other way, the inertia plus spring pressure drive the next cartridge in and lock the bolt. A not cycle diagnosis really requires knowing what completed and what didn’t in the cycle. Then some of the other questions matter. [/QUOTE]
