Wilson Combat
The Wilson Combat AR-15 Low Profile Gas Block in .875" bore is a precision-engineered component built for shooters and builders who won't compromise on reliability. If you're assembling a custom AR or upgrading an existing rifle, a quality gas block is the foundation of consistent cycling—and this one delivers the durability and low-profile design that works seamlessly under modern free-floating rail systems. Wilson Combat machines this block from hardened chromoly steel and finishes it with a blacknitride coating to resist corrosion through extended shooting sessions.
What sets this gas block apart is the attention to detail in its engineering. The bore is precision-machined to .875" to match Wilson Combat barrels or any quality aftermarket barrel in that spec. The low-profile footprint sits well underneath most handguards, so you won't have fitment headaches during your build. Set screws hold it securely to the barrel, and Wilson includes hardened screws plus a gas tube roll pin in the box—you get what you need to install it right without hunting down extra hardware.
Whether you're running a high-round-count competition rifle, a duty build, or a precision hunting setup, heat dissipation and leak-free operation matter. This block's mass and design manage both, so your gas system stays tuned through thousands of rounds. It's the kind of component that doesn't demand attention because it simply works—exactly what you want from a gas block.
