It's a Colt!
Don't complain about the price, it is what it is and AU delivers. This is the real deal straight from Colt to you through AU and they did a great job getting it to me. For anyone looking to do a clone correctly or if 10.3 is what you want look no further.

Colt CQB
I am in the process of re-barreling several agency rifles with the 10.3" Colt CQB barrels. These are excellent quality barrels and the sales associate (Jack) is a pleasure to work with!

Great barrel
Bought this for my mk18. The barrel mounted nicely to the Colt upper receiver and BCG. Unsure of gas port size, but Im using an H2 buffer in this build and everything is functioning properly. Very pleased so far
