Rosco Manufacturing Bloodline

Description

Product Overview

The Rosco Manufacturing Bloodline .300 AAC Blackout 8.2mm heavy barrel is built for AR-15 pattern pistol and SBR use where suppressors are part of the plan. At 8.2 inches with pistol-length gas and a .750 gas block journal, this configuration is designed to maintain reliable function while optimizing velocity and consistency across common subsonic and supersonic loads. The 4150 CMV steel construction with a nitride finish helps the barrel hold up to repeated use, and the 5/8x24 threads make it ready for standard .300 AAC Blackout suppressor mounting.

Key Features

• 8.2 in barrel length for a compact .300 AAC Blackout setup for pistol and SBR builds
• Pistol-length gas system with a .750 gas block interface for intended suppressed or mixed-load reliability
• 5/8x24 threads for standard .300 AAC Blackout suppressor compatibility
• Heavy profile for added stiffness and consistent accuracy potential
• 1/7 twist rate to support common .300 AAC Blackout bullet weights
• 4150 CMV steel with nitride finish for improved wear and corrosion resistance

If you’re building a compact .300 AAC Blackout AR platform that’s meant to run clean and consistent with a suppressor, the Rosco Bloodline 8.2 in heavy barrel is a purpose-built option.
