LOW PROFILE GAS BLOCKS FOR AR-15 Reviews & Ratings

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.

Not Faxon quality

I purchased four of these and had problems with three of them. The first was too small to fit on a .750 barrel and I returned it. The second was a very tight fit with one end the correct diameter and the other slightly too small and required some sanding to fit. The third cracked on one end when I tightened the screws. Only one worked properly. I will most likely replace it since I am concerned that with so little mass, it will eventually heat up and crack. These look good and are lightweight but the quality isn't what I expect from Faxon and their excellent barrels. Do not recommend. The nitride Brownells version is better.

Bag tolerance gas block

Purchased this gas block to install on an 18 inch Faxon Pencil Barrel and the darn thing would not fit! Went to my local dealer which sells 16 inch Faxon Pencil barrels and it would not fit on that one either. Expected more from Faxon! In the process of trying to return this and the pencil barrel I ordered.
