What is the FAXON FIREARMS - LOW PROFILE GAS BLOCKS FOR AR-15?

Perfect for any rail system, these ultra-low profile gas blocks are the ideal companion for Faxon Firearms (or any other) barrels with a standard diameter gas journal. Made from high-strength steel, all Faxon gas blocks are a matching black luster to their barrels.


For lightweight builds, the block is drilled through the middle of the profile. The gas block clamps on to the barrel using 3 allen keys on the bottom of the block.


Faxon Firearms highly recommends the use of Loc-Tite or similar thread-locking compounds. Gas blocks will get very hot, so pick a compound according to your intended use of the firearm.

Faxon Gas Block
First time using a Faxon 3 screw gas block. I got it as a picked up a Faxon barrel on special. Impressed with the quality of the block no difference is length than standard 2 screw blocks. Pilot hole lined up perfectly. I only dimple the first set screw.

Great Gas Block
Installed this gas block on a Faxon pencil barrel and it fit perfect with no problems. Overall fit and finish was excellent. The main reason I went with this gas block was to ensure that it would fit and run without any issues on a Faxon pencil barrel. I couldn't be happier. Fits perfectly under the Aero Atlas S-One hanguard. I would definitely recommend this gas block!!!

LT 308 Block
In my desire to piece together a light 308, I chose this Faxon GB and put it on a Faxon 18" rilfe length Pencil Bbl. I really wanted an adjustable block, but now that I have shot it, I'm convinced this was the right choice for the goals of this build. I have been running some hot surplus ball down the barrel, and the block is staying put (no set screw dimpling was performed, just LocTite and torque). Fits , with plenty of headroom, under a Midwest Ind. SS MLock float handguard. Oh, and the roll pin for the gas tube is staying put too.

3 builds and no cycling failures
I built my first rifle with an unknown name brand gas block. It had cycling issues and it did not feed on 10th or 20th round fired. So I decided to replace it with this gas block, Brownell's nitride gas tube and viola! I've had no issues since. I built 300 BO and 308 ARs using same gas block, no problems.

Come on Faxon
Installation was easy, fit well. That said, a couple suggestions for Faxon. A gas tube roll pin would be nice, and a dimple on your barrel to match this gas block to would be helpful.
