Wilson Combat TR-LPGB-M Lo-Profile Gas Block .875" Black Nitride 4140 Chromoly Steel

The Wilson Combat TR-LPGB-M is a precision-machined medium-length lo-profile gas block engineered for AR-platform rifles. Built to deliver a secure, reliable gas seal in a low-profile package, this gas block is precision bored to .875" and uses a .400" set screw spacing for solid mounting on the barrel journal.

The TR-LPGB-M is precisely machined from hardened 4140 chromoly steel and finished with a corrosion-resistant black nitride coating that holds up to field use and resists the elements. The lo-profile design clears free-float handguards and keeps the upper receiver's sight line clean for optics and accessories.

Installation hardware is included: the gas block ships with hardened set screws for clamping to the barrel and a gas tube roll pin for retaining the gas tube. Drop it onto a compatible AR-platform barrel and pair it with your existing gas tube and handguard setup for a complete, low-profile gas system.
