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. 

Specifications (.750"):

  • Barrel Compatibility: .750"
  • Weight: .07 Lbs
  • Width: 1.00"
  • Height: ~1 & 7/32" 
  • Mounting: 3x Screws (Allen Key interface)

Gas block does not include the gas tube roll pin. Faxon includes gas tube roll pins with gas tubes.

    I just rec'd and installed this lightweight (1.18oz) gas block on my new Faxon .300AAC 16" barrel. First, I noticed it was extremely tight but with a slight bump from a wooden block it slide right on. Second, I noticed there were no markings on the block or the barrel to be able to match the gas block port with the barrel gas port perfectly. My previous upper build with a different brand was center marked on both parts (just a note to Faxon to maybe add to future manufacturing). Overall I am satisfied with my purchase.

    Waste of money. Luckily i had another gas block around to use. I had purchased this with the 7.5 gunner profile pistol barrel in 300blk. The machining on the gas block must have been bad since this it was way too small to fit the barrel. Maybe just a QC issue.

    The Faxon gas tube had to be trimmed 1/4 to fit.

    When I went to put the gas tube in the gas block I found that the gas tube would not go all the way in to pin it. I looked inside the gas block and it was full of metal shavings and dirt after spending 15 min digging all the metal shavings and dirt o

    Gas block was full of metal shavings and dirt I had to spend 15 mins getting as much as could the put the gas tube on. Very disappointed in that. It did come in on time and fit to the barrel good have not test fired the rifle to made sure it works but maybe it will be fine
