Surplus Colt Delta Ring Assembly

Solid piece of equipment. Went on my rifle fine, locked up great, stiff as a rock. It's definitely a chore pulling back the slip-ring, but I have no doubt about the secureness of the handguard. Mine came rather gummed up but some quick cleaning fixed it and now it looks brand new, besides the area around the gas tube where it looks like some paint cooked off on the c-clip after a high round count session. It's surplus, after all. Has history and works great.
