    Aero Precision has just launched their new low profile Adjustable Gas Block for AR-15 rifles and pistols.  Adjustable gas blocks add a tunable option for shooters looking to use suppressors, or to be able to adjust for varying loads that may otherwise be finicky with a standard gas block.  The low profile aspect of Aero Precision’s Adjustable Gas Block allows mounting on any AR platform with a free floated barrel system.  Aero Precision’s description of their Adjustable Gas system can be read below:



    • Standard low-profile design provides great fit under slim profile free float handguards including the Aero Precision ATLAS series of handguards
    • Adjustment screw is held in place by a spring and detent, providing repeatable audible “clicks” upon adjustment removing the need for secondary set screws that can come loose under recoil
    • Custom machined stainless-steel adjustment screw provides 15 gas adjustment settings
    • Carbon fouling is channeled to a sacrificial chamber to help prevent carbon locking, as well as provide an access point for solvent in the event carbon locking does occur
    • User-serviceable design allows for service and cleaning of the gas system


    • Machined from 4140 hardened steel
    • Nitride coated
    • Compatible with barrels utilizing a .750 gas block journal (.625, .875 and .936 coming soon!)
    • Attaches to barrel via 10-32 x 3/16 knurled set screws


    • Assembled Adjustable Gas Block
    • One 6″ 3/32 adjustment wrench for easy gas block adjustment underneath installed handguard
    • Replacement spring and detent included

    Please note: We do not recommend the use of red threadlocker on the threads of the set screws. If you decide to use threadlocker we recommend using the non-permanent variety.
