Rosco Manufacturing Stray Dog AR-15 5.56 NATO 16" Mid-Length 1:7 Barrel - Black Phosphate

The Rosco Manufacturing Stray Dog is a duty-grade 5.56 NATO replacement barrel built for hard-use AR-15 builds. Sharing its core geometry with Rosco's Bloodline USASOC-profile barrel, the Stray Dog pairs a 16" chrome-lined bore with a classic black phosphate finish for a no-nonsense look favored by cloners and purists alike.

Machined from 4150 CMV steel with a 1:7 rifling twist, the Stray Dog is chambered in 5.56 NATO and uses a mid-length gas system for smooth cycling and reliable extraction across a wide range of ammunition. The chrome-lined bore supports sustained use and easier cleaning, while the phosphate exterior coating protects the steel and gives the barrel its traditional matte-black SOCOM appearance. The muzzle is threaded 1/2x28 for compatibility with standard AR-15 muzzle devices.

Whether you are assembling a faithful retro clone or building a duty rifle from the ground up, the Stray Dog delivers Rosco's proven manufacturing quality in a time-tested 16" mid-length configuration that drops into any standard AR-15 upper.
