Specifications
Why Choose the Faxon Integral® Series
The Faxon Integral® Series eliminates the need for pinning and welding by machining the muzzle device directly into the barrel blank. This results in a perfectly concentric assembly, superior durability, and a cleaner aesthetic while keeping the overall length at 16" for legal compliance. Whether you choose the Gunner Brake or Flash Hider variant, the Integral Series gives you unmatched flexibility and build freedom.

Pretty good barrel
I like the profile of the barrel feels good and well balanced. Only issue I have is it doesn't seem to stabilize 55 grain ammo very well, I get the occasional key hole. I thought the 1/8 twist would be good for light projectiles compared to the usual 1/7. No issue with 62 grain or heavier. Overall it's a good barrel and a good option for those who can't or don't want to pin and weld.
