Rosco Manufacturing Husky AR-15 5.56 NATO 14.50" Chrome Lined Phosphate 4150 CMV Barrel - Mid-Length

The Rosco Manufacturing Husky is a heavy-profile AR-15 barrel chambered in 5.56 NATO. The Husky profile is designed to help defeat heat and reduce barrel whip during extended strings of fire. Cut to 14.50" from 4150 Chrome Moly Vanadium (CMV) steel, it is button rifled with a 1:7" twist.

The bore and chamber are chrome lined for long-term corrosion resistance and extended service life, then finished with a protective phosphate coating for a durable, low-reflectivity exterior. A mid-length gas system keeps the action cycling smoothly.

This is the HSK-145-SOC-556-7-MCL - a current-production Rosco Manufacturing barrel ready to drop into your next AR-15 upper or replace a worn factory tube.
