WMD Guns Pistol Length Gas Tube Nitride Finish Black 1 NMGTPL UPC 855899003522
Product Description
The WMD Guns Pistol-Length Gas Tube in Black Nitride (SKU: 1-NMGTPL / UPC: 855899003522) is an upgraded AR-15 gas system component engineered to enhance cycling reliability and corrosion resistance in short-barreled rifles (SBRs) and AR pistol platforms. Utilizing WMD's proprietary NiTromet™ salt bath nitride process, this gas tube features an ultra-hard, slick surface treatment that drastically reduces carbon build-up and erosion under intense gas pressure and rapid fire.
Formed from high-grade stainless steel to precise mil-spec bend profiles, the 1-NMGTPL tube provides seamless gas block interface and proper key alignment inside the upper receiver. Unlike standard raw stainless gas tubes that reflect light, the deep black NiTromet™ finish offers a sleek, non-reflective aesthetic that blends in with dark handguard assemblies while delivering superior thermal and chemical protection.
Packaged complete with a heavy-duty stainless steel gas block roll pin, the WMD Guns pistol-length gas tube is a drop-in component for custom AR-15 pistol builds chambered in .300 AAC Blackout, 5.56 NATO, 9mm, or .223 Remington.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Direct fitment for all AR-15/M4 barrels with a pistol-length gas system (approx. 6.75" tube length). Compatible with standard low-profile and railed .750", .625", or .936" gas blocks. Will NOT fit carbine, mid-length, or rifle-length gas system barrel journals.
- Ensure the host firearm is completely clear, magazine removed, and chamber visually and physically verified empty.
- Insert the gas tube into the gas block port, ensuring the gas port hole faces downward directly into the gas block passage.
- Drive the included gas tube roll pin through the gas block collar using a dedicated roll pin starter punch until flush on both sides.
- Guide the gas tube through the upper receiver gas tube hole, verify free clearance through the barrel nut, and test smooth sliding engagement with the bolt carrier gas key before torqueing handguard cross-bolts.
