Colt M4 CQB 10.3 inch 5.56mm Barrel Assembly w/ Fixed Front Sight

Excellent Oem Colt barrel in the wrapper. Original Colt quality and the best price on the internet by far!!

Bought this for a MK18 build but the front sight is NOT F-marked. It has codes I’ve NEVER seen on a fixed front sight. BUYER BEWARE. I’ll update my review IF I can get it to sight in with a flattop receiver. The makings on the left side are “AOK” and on the right side are an unknown circle forge ID possibly and “76” to the right of that. Can’t find anything about those marks anywhere.

Really happy with the product came in blue back sealed, no damages, 100% colt product and shipping was fast!!

I picked this up on impulse to finish out a MK18 carbine. This is a great quality barrel. It came packaged very nicely and went together without issue. I took the carbine to the range and was pleasantly surprised with the accuracy. It was gassed nicely with and without a suppressor using an H2 buffer.

colt mk18 commando now, looks super cute!!!!

Great price, great shipping speed and communication.

If you’re into that sort of thing, get this pronto

Great on hard-to-find items and an overall good experience. Only thing I could gripe about is their rather stern guidelines for returns and it is for this reason I may limit my purchases to only the rarest things that I may need.

Received this barrel yesterday and it looks good! This barrel came with the sling mount on the front!!! I'm still waiting on the a delta ring assembly to arrive before I put the upper together.
