Awesome Barrel Assembly
Super nice Colt barrel assembly for my Mk18 Mod 0 build. Fits great in my BCM upper and the headspace is within spec for my Colt bcg. Great deal and I couldn't be happier.

Hard to come by. Perfect for CQBR/MK18 clones without having to send out your barrel to get chopped and rethreaded.

Colt 10.3" Barrel
I purchased this genuine Colt 10.3" barrel and I have to say there is no denying its quality. Arms Unlimited often has these specialty items at fair prices unlike other online vendors so I have to thank them for their support.
