[QUOTE="rc508pir, post: 3009104, member: 40091"] I didn't say there was a reliability improvement in pistons over DI. A bolt in a DI gun will break before it does in a piston gun, because of the heat and pressure, inside the BCG. I'm not saying the bolt is going to break after a few hundred rounds. The service life on a M4 bolt is 8 to 10k. After that, its replaced do to fatigue from the heat and pressure from carbine gas sys. The M16 bolt service life was 18Kk+ service life. You don't have that issue with a piston AR. You have to remember, the gas expanding in the BCG is also forcing the bolt forward as the Carrier is forced to the rear. That pressure and heat stresses the bolt and over time, especially if you're getting it hot. [/QUOTE]
