[QUOTE="Glocktogo, post: 2327309, member: 1132"] While I agree with this premise, that's not necessarily entirely accurate. I have done testing that indicates a DI platform will run both dry and dirty when utilizing a coated BCG. Specifically, I have a BCM Ion-Bond BCG in my RR Colt M16A1. The upper is a Colt 6933 11.5" with an AAC M42K suppressor. I tested it in excess of 800 rounds, [U]full auto and suppressed[/U] with NO LUBE applied during the test period. Zero malfunctions. The gun was inspected periodically and when complete, it was beyond filthy. In some areas, the fouling was VERY thick. Yet the friction surfaces of the BCG were fairly clean and no galling of the BCG or upper were found. I did this specifically because I wanted to know if it was possible to build a DI gun that would exhibit superior reliability, contrary to the frequent refrain that DI AR's are less reliable. Now with that said, I'm still a stickler for lube and chamber cleaning. You can run a DI AR for a LONG time without routine cleaning, so long as you periodically scrub the chamber and keep her wet. ;) [/QUOTE]
