This is the old gun, 1/12 twist. 1/7 didn't come out until much later.

BAR belt, could hold about four or five mags per pouch. That would give him about twenty five or thirty mags. The flash hider on the rifle just behind him is interesting too...I wonder if it came from a Stoner? That would have been the time when prong flash hiders were still around and many didn't prefer those.

Jim, that looks like a standard bird cage flash hider to me. Did y'all notice the hinged trigger guard missing on the XM?

OK, I thought it looks like there's a transverse hole straight through and looked longer. Probably not, time and space... I know the standard Stoner looks the same as the birdcage.

The XM177E2 had 'sound moderator' to reduce the noise and flash. Depending on who you believe, it was not without problems. The moderator tended to improve reliability of function, but did increase carbon fouling. Some problems were had with tracer ammunition. While I was in Viet Nam I did get notification that couple of XM177E2's were being sent for our platoon to evaluate for possible replacement for the M3A1 submachine gun on tanks. We never did get them, for as soon as they arrived they were appropriated by the Battalion Commander and the S-3. Can't say how it would have worked for us, but it did allow the brass at base camp to look cool on their stroll to the chopper pad.

There's one of those in the post museum in Ft Lewis Wa...the curator was unaware.

I carried an XM177E2 (we called them CAR 15s). Never had any problems with it. The E1 with the shorter barrel was the one that had problems.
I brought home all of it except the lower receiver. When I got home I bought an early AR 15 and put my CAR 15 "parts kit" on the lower. I also registered it as a short bbl'd rifle AND since some claimed that the flash hider was a suppressor - BS! took a machine to measure the sound difference - I registered it as a suppressor just for S&G!
Still have it and shoot it occasionally. It is also my car gun when traveling - like going to Mo. next week.
