    16” Gunner Grendel

    Posted by Matt on Sep 28th 2021

    A great lightweight barrel, surprisingly accurate. I am using a 3x9 VX-2 scope with a heavy German #4 reticle, and was still able to get decent groups with a variety ammo. My hunting load is a Barnes 100 gr TTSX at a max charge of RL 15, and this barrel seems to like these bullets as much as it does 123 gr ELDs.

    16” 6.5 Grendel Gunner

    Posted by George Swarts on Nov 7th 2020

    Dead on accurate. Love this barrel. It’s my hunting rifle for the year and I couldn’t be happier. Balance of rifle feels great and it is more accurate than me. Shot groups of 3 at 50,100,150 and all were .75 and less.

    Posted by Noah on Feb 12th 2019

    I purchased this barrel after receiving a complete joke of a barrel from another company and this is a magnificent piece in every aspect!! Fit and finish are second to none and the accuracy is astounding as well. I’d highly recommend this or any other Faxon barrel to anyone in a heartbeat!!

    As a hunter, I give this a 5 star. I wanted an exceptional 5R rifled barrel for my 6.5 Grendel. I did not want to to settle for less and Faxon Firearms delivers quality 5R barrels for a reasonable price. I will be educating others about Faxon quality & value.

    Accurate 6.5 Grendel Barrel

    Posted by Jonathan Freeman on Jul 31st 2018

    Installed this barrel on an Aero Precision receiver set, FailZero BCG and trigger. Th complete build is under 7lbs. After taking a few shots sighting in my scope, the groups were tight. 100 shots at 100 yards were in a 2 inch group. The barrel performed great when hot too. This is my first Faxon barrel and it won't be my last.

    Purchased this barrel for an upcoming build. Machine quality is excellent and fitment into upper is perfect. Build is not finished so no comments on accuracy, but build quality and price is unmatched.
