Ahmad’s take:

Guys, these barrels are unreal. Traditional barrels are turned and relatively easy to manufacture. These require special CNCs; they start from a 4150 blank and machine down until a barrel + gas block is formed. No more gas loss/leak, dimpling, screwing, pinning, thermal shift, etc. This is the most bombproof gas block setup in the industry. And because there’s no gas loss, HM can get away with a more conservative port size.

These barrels have low recoil and take very well to a suppressor. Medium contour, and best of all, world-class sub minute of angle accuracy. These things can really group. You won’t be disappointed.
