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 what I expected

I purchased a Faxon mid length gas tube so I would keep the same manufacturers. To my surprise the tube bottomed out 1/4 inch short of the pin hole. I had to shave off the tube to fit correctly. I don't believe the tube was off or out of spec. I believed having the same manufacturer would save me of problems but I was wrong.
