Rosco Manufacturing Bloodline 5.56 AR-15 Bolt Carrier Group - Melonite

Rosco Manufacturing has taken the basic bolt carrier group design laid down by Stoner and matched it with feedback from military, law enforcement, and civilian shooters to produce their complete bolt carrier group, built to higher than mil-spec standards.

Features:

• M16 spec, full-auto rated carrier
• Compatible with .223 Rem / 5.56 NATO / .300 Blackout
• Upgraded extractor
• Magnetic particle inspected bolt, shot peened
• Durable Melonite finish
• Properly staked gas key

Each Rosco BCG is shot peened to normalize and stress relieve the steel, with a properly staked gas key that won't come loose under harsh use. The entire assembly is treated with a corrosion-resistant, low-friction Melonite finish for a lifetime of smooth, reliable service.

Rosco Manufacturing got its start producing high-quality, hard-use precision rifle barrels and has since expanded into a full line of serious-use parts and accessories. Their production facility is in Central Falls, Rhode Island, so every component is 100 percent made in America, by Americans.
