Large gas port.
Gas port is very large. It pin gauged at 0.074". It's going to be very overgassed.
-
Great for suppressed SBR
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.
-
Perfect for hrt build
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.

***BE AWARE***
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.
