Aero Precision Adjustable Low Profile Gas Block .875 – AR-15

The Aero Precision Adjustable Low Profile Gas Block gives you precise control over your AR-15's gas system. By tuning gas flow to match your ammunition, suppressor setup, or buffer weight, you can reduce recoil, minimize port pop with suppressors, and improve reliability across different loads. This adjustable block is particularly useful for suppressed rifles, where excess gas can cause excessive bolt speed and carrier tilt.

Machined from steel with a black nitride finish for corrosion resistance and durability. The .875-inch diameter fits standard AR-15 barrels with a .750-inch gas journal (requires a .875 adapter or specific barrel profile). Installation requires set screws and proper alignment—basic armorer skills recommended. The adjustment screw is accessible from the front, allowing tuning without disassembly.
