Definitely recommended

Brownells USA Good product 11/06/2018

I have used these in all of my custom builds, and my duty weapon has one of these. Never had an issue with any of mine. They have all fit and functioned as promised.

Not recommended

Brownells USA Missing Roll Pin 20/07/2015

I received the buffer and noticed it was missing the roll pin that holds the buffer to the metal tube and had to return for a refund. Hard to believe it left Colt that way :|
