WMD GAS TUBE PISTOL LENGTH NITROMET$14.40
Availability: In Stock
The WMD 9mm 16.5" NITROMET barrel is a government-profile AR-9 component built by a team of in-house metallurgists and coating specialists who understand what separates a quality barrel from one that merely functions. If you're building or upgrading a 9mm AR pistol or short-barreled rifle, this barrel delivers the precision and durability you need in a compact package.
WMD Guns manufactures and applies their own coatings in-house, which means tighter quality control and consistency across every unit. The 16.5" length strikes a practical balance for shooters who want a full-length 9mm upper without excessive dwell time, while the 1:10 twist rate is optimized for 9mm projectiles. The black nitride finish resists corrosion and wear—critical for a component that cycles hundreds of rounds and demands reliability.
The 1/2x28 thread pitch is the standard for 9mm suppressors and muzzle devices, so you'll have no trouble finding compatible attachments if you go that route. Whether you're running an AR-9 for sport shooting, home defense, or suppressed duty, this barrel handles all of it without fuss. WMD's reputation for in-house precision plating means you're getting a component built to exacting standards, not a commodity part.
| Caliber | 9mm |
| Barrel Length | 16.5" |
| Profile | Government |
| Twist Rate | 1:10 |
| Thread Pitch | 1/2x28 |
| Finish | Black Nitride |
Yes, the government profile and standard AR threading make this barrel compatible with any AR-9 upper receiver. Verify that your receiver accepts a .750" diameter profile barrel at the gas block area.
The 1/2x28 thread pitch is the industry standard for 9mm suppressors and flash hiders. Nearly all commercial 9mm suppressors and muzzle devices use this threading.
The 1:10 twist rate is designed to stabilize typical 9mm projectiles (115–147 grain) across the velocity range produced in this barrel length. It ensures consistent accuracy and reliable bullet performance.
WMD manufactures and applies their own coatings in-house, combining metallurgical expertise with precision plating. This in-house process reduces variables and ensures consistent quality on every barrel they produce.
