Aero Precision Adjustable Low Profile Gas Block .750, Nitride

Aero Precision Adjustable Low Profile Gas Block .750, Nitride

The Aero Precision 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.

Features:

  • 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

Specifications:

  • Machined from 4140 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

Includes:

  • 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.
