Colt M4 Commando 11.5 inch 5.56mm Heavy Barrel

Gas port is very large. It pin gauged at 0.074". It's going to be very overgassed.

Great barrel for suppressor host. Rigidity of this barrel profile helps to minimize point of impact shift with the added muzzle weight of a suppressor.

This is the perfect profile for an FBI HRT clone. The gas block is pinned in but a vise, punch and hammer take care of them in no time.

Excellent barrel , tested for function , will become part of SBR build.

Excellent product with no complaints.

Quality Colt item in factory plastic packaging. Happy with purchase

Great barrel, BUT, be aware these barrels have a .073 diameter gas port. I have 3 examples of this barrel and all three measure the same, .073. Unless pared with an adjustable gas block or gas port restrictor your rifle will be overgassed. For suppressed use it will be severely overgassed. The gas port size should be listed in the product description.

Item just as described, Factory Colt!! "Recommendations" Please do something in regards to you're shipping/packaging Dept. Otherwise, would be 5 STARS?

This product was new in the bag and exactly what it said it was.
