I just watch a video of some gunny(Wx) firing an 10.5inch M4 with/without a can. At first I thought it was a USMC training video, but the lower had a right side safety & ball-n-chain logo and it looked like he changes the bolt & carrier before using the can??
It is posted by 2nd Marine Division Combat Camera
@ 1:35 you can see he used the right side saftey
@ 1:45 you can see he install a carrier.

Anybody know if the Marines have also decided to go with short barrels and ported carriers??
I know gamtech has a ported carrier,, and for the price, they are very proud it it.
