Upgrading your AR-15 gas system with the Aero Precision Adjustable Gas Block will allow you to fine-tune your competition build and take your weapons to another level. Being able to manage the excess gas will help you reduce recoil and customize your rifle to fit your exact shooting style.


The Aero Adjustable Gas Block is designed to match the profile of standard low-profile gas blocks, allowing you to fit most free-float handguards. The Aero Precision difference is the adjustment screw and the spring allowing you up to 15 different gas positions that can be adjusted between fully open and fully closed. This spring keeps the adjustment screw in place and removes the need for additional set screws. The Aero Precision Adjustable Gas Block design helps to prevent carbon locking by funneling carbon fouling to the sacrificial chamber. These innovations represent Aero Precision's superior quality and intelligent design.


If you want to mitigate recoil as much as possible, then the Aero Precision is an essential upgrade for your competition build. When using a suppressor, this gas block is especially useful because it helps you manage the gas, resulting in eliminating excess blowback. If you change your ammunition grain, you can easily adjust the gas block to fit the new load for maximum precision and consistency. With 15 different gas adjustment settings, this gas block will allow you to make the most precise and finely tuned competition build possible.

Whether you need a .875 gas block or .936 gas block for your bull barrel or a .625 gas block for your pencil barrel, we have the correct size gas block for you. Step up your game by upgrading your rifle with high-quality AR-15 parts from Wing Tactical.
