Product Description
The Noveske Rifleworks "OG" 12.5" 5.56 NATO Stainless Steel Barrel Kit (MPN: 07000541) is a premier, match-grade barrel assembly purpose-built for short-barreled rifles (SBR) and AR-15 pistol builds requiring extreme precision and uncompromising duty reliability. Crafted with Noveske's iconic "OG" profile, this 12.5-inch barrel delivers optimal velocity and dwelling efficiency while maintaining superior balance and maneuvering capability in tight environments.
Precision CNC-machined from 416R stainless steel and finished in a matte, non-reflective bead-blasted silver, the barrel features a 1:7" twist rate optimized for stabilizing heavy 5.56 NATO and .223 Remington match projectiles (such as 62gr, 69gr, and 77gr loads). Utilizing Noveske's proprietary 5.56 Match chambering, it provides exceptional sub-MOA accuracy without sacrificing reliable feeding under high-volume suppressor or duty firing schedules.
This complete match barrel package includes a factory-pinned low-profile gas block with cross-pin alignment, a mid-length gas tube, and a individually headspaced bolt assembly. By providing a bolt factory-matched directly to the barrel's extension and chamber, Noveske eliminates headspace guesswork, providing custom armorers with a turnkey, competition-ready foundation for high-tier AR-15 custom upper receivers.
Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Fits standard Mil-Spec AR-15 upper receivers. Features a 1/2x28 muzzle thread pitch and mid-length gas port spacing. Includes a factory-pinned low-profile gas block, mid-length gas tube, and headspaced bolt assembly. (Note: The included headspaced bolt drops directly into any standard Mil-Spec AR-15 bolt carrier group body).
- Perform a complete firearm safety check: drop the magazine, lock the action open, and visually/physically inspect the chamber to verify zero live rounds are present.
- Clean and inspect the upper receiver barrel extension socket and barrel extension threads, ensuring they are free of carbon and metal chips.
- Apply a thin coat of aero-grade anti-seize grease to the upper receiver barrel extension threads.
- Insert the barrel extension into the upper receiver, aligning the indexing pin into the upper receiver slot without forcing or twisting.
- Torque your barrel nut to manufacturer specification (typically 35 to 80 ft-lbs) using a dedicated armorer's wrench and torque wrench.
- Assemble the included headspaced bolt into your preferred bolt carrier group chassis, verifying smooth cam pin rotation and firing pin retention before receiver closure.
