Love this barrel!
by Mikey -
A solid 5 star performance on this barrel!
It will beg paired with a suppressor shortly, but right now is sporting the KAK 5” muzzle device to work inside the handguard till then.
Gas block seated snug against the collar, seats into upper tight, beautiful finish, functions flawlessly.
.300 blk upgrade
by Marty Rocket -
I sold my .300 blk 10.5" pistol to build an upgraded .300 blk 7.5" pistol to run suppressed. Thus the upgrade to a Faxon 7.5" Gunner barrel. The build is on a Desert Tech Quattro lower, the one that came out at Shot Show 2024. This is the one that runs 53 round polymer magazines. The lower comes with Ambi magazine and slide release controls, all I added is the Ambi safety and Rise Armament drop in trigger. The Hogue overmolded finger groove grip will finish the lower nicely. The barrel gets an adjustable Aero Precision gas block and a Strike Industries Oppressor set up until I get the suppressor. This will be quite the up grade from the prior pistol, Thanks Faxon for your high quality barrels, my 4th or 5th. Go Primary Thanks for the great price.

This is an awesome barrel, it sends supersonic freedom pills perfectly, I haven't tried subsonic yet.
