The Noveske OG Barrel 556 12.5" LW Bolt brings Noveske’s well-known stainless precision to a compact AR-15 build. Machined from 416R stainless steel with a 1:7 twist and a lightweight contour, this 12.5-inch barrel is designed to balance accuracy with fast handling. A hand-polished Noveske Proprietary Match chamber and extended feed ramps support smooth cycling and consistent performance, while the bead-blasted finish delivers a clean, low-glare appearance. The barrel is threaded 1/2x28 and ships with a pinned low-profile gas block, matched gas tube, and headspaced bolt for a ready-to-build package.

This configuration uses a carbine-length gas system tuned for reliable operation across a wide range of .223 Remington and 5.56 NATO loads, making it a strong choice for range work, training, and general-purpose carbine builds. The included headspaced bolt simplifies assembly and helps ensure dependable lockup and longevity. With thoughtful details like a 60-degree muzzle crown and serialized quality control, this barrel reflects Noveske’s reputation for careful craftsmanship and performance-focused design.
