The Aero Precision "Click" Adjustable Gas Block allows the user to finely tune their gas system for any application. This is particularly useful for managing excess gas to reduce blowback on suppressed firearms, or competition builds where the shooter is looking to mitigate recoil.

Note from Phillip: These are Aero's updated version with the Bronze adjustment screw. A properly dimpled barrel is highly recommended for the most reliable installation of these gas blocks under hard use conditions.


  • Standard low-profile design provides great fit under slim profile free float handguards
  • "Click" style of spring and detent adjustment for reliable function under heavy use and recoil
  • Stainless-Steel Adjustment Screw with 15 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
  • Knurled Set Screws for reliable installation under heavy use.


  • Machined from 4140 Hardened Steel
  • Black Nitride Finish
  • Compatible with barrels utilizing a .750 gas block journal
  • 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
  • FREE Gas Tube Roll Pin courtesy of Bexar Arms!

Please note: Aero Precision do not recommend the use of red threadlocker on the threads of the set screws. If you decide to use threadlocker they recommend using the non-permanent variety such as "blue" Loctite 243.

    Posted by Kevin on Feb 13th 2024

    I had issues with a new build I had and the gas block was junk I bout this one to replace it. It fixed all my issues and is easy to install! FYI DONT buy anything from delta team tactical when you have an issue they will take months to respond to you!

    That included roll pin makes a phenomenal difference. I will be purchasing from Bexar/Bear in the future.

    AP Adjustable Gas Block

    Posted by Zachary Rice on Jul 29th 2023

    This is my second AP adjustable gas block. Both of my .308 ARs were really over gassed. This gas block tuned them up very easily. Always a pleasure dealing With Bexar Arms

    Adjustable Gas Block

    Posted by EJ on Nov 11th 2022

    Made shooting my rifle suppressed more pleasant. I can shoot faster without gas blinding me. Can even make adjustments with my suppressor on.

    Well made gas block

    Posted by Daniel on Feb 11th 2022

    This gas block is top shelf. I’m able to adjust the gas in 223/5.56, 7.62x39, 6.5 Grendel, and 308/7.62x51 to shoot steel and brass with no cycling issues. I’ll also add that these calibers also are used with various barrel lengths with different gas port locations. At a very reasonable price, I can get the gas just right.
