My USAF GUU-5/P carbine build.

I prefer the M16 carriers due to the increase mass for feeding. In my carbine builds I have used M16 BCGs, a stock USGI M4 spring, Wilson Tactical Comp instead of flash hider, and a 3.6 oz H-buffer. Really smoothes out the snap of the little carbine barrels. I really noticed it on the 16" pencil barrel build I did.

Ah, the CHROME 601 carrier!

I just checked all my carriers and found out that most of my carriers were not staked. Any tricks to doing them or just go for it ?

[imarangemaster]

I usually stake them. They can (and will) come loose:
