Dose this item fit on a 5.56/.223 barrel? Expert Answer

Yes, however you must match the barrel's gas journal diameter. Most pencil barrels have a .625 diameter and most other non-bull/heavy barrels feature a .750 diameter. You will need to verify or measure the gas block diameter of your specific barrel and match it to the appropriate diameter.

Maybe the best SS gas block around by MattP, July 28, 2017

At first glance this looks like every other gas block around. It is not- it's way better for a number of reasons. First, the side cutout reduces not only weight but friction when you are installing it, esp if you have a tight fit to the barrel. Secon...

my go to non adjustable gas block by dan, Verified Owner, February 5, 2023

These gas blocks just plain work and they look pretty good too! I generally use faxon or ballistic advantage barrels because they are always gassed just right where all you need to do is tune with the spring instead.

nice gas block by Joshua, Verified Owner, September 11, 2024

Runs great with my 7.5 in Faxon barrel and Faxon gas tube. I had issues with other gas blocks and not cycling subs being under gassed. Switched everything to make Faxon 1:5T barrel and included a lightweight BCG by Faxon and everything is good to go.

Perfect for my build by Derek, November 29, 2020

Assembled onto a Faxon 14.5” 5.56 pencil barrel. Advice: this gas block is very delicate, due to its thin, lightweight construction. Put it on a barrel before you go clamping it in a Vice to install the gas tube pin.

Fit like a glove! by eddie, December 20, 2018

Installed the Faxon gas block on a Faxon Gunner barrel and the fit was perfect. The gas port lined up with the one in the block when the block was up against the cut ledge nearby. Would I buy again? YES!

Product Info for Faxon Firearms Ultra Low-Profile Gas Block

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 our gas blocks are a matching black luster to our 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.
