Rosco Bloodline 10.5″ 300 Blackout Barrel

All ATF/NFA Rules Apply – See NFA tab for details

This 10.5” 300 Blackout barrel was designed for SBR/ Pistol use in conjunction with suppressors. The 10.5” Rosco barrel was made to be a direct replacement for any MK 18 platforms that are currently in 5.56 NATO. The 10.5” barrel is also perfect for carbines which require a slightly longer rail in order to run PEQ-15’s, D-BAL (series), or any laser aiming devices comfortably.

The Rosco Bloodline 10.5″ 300 Blackout barrel was created with input from SOCOM end users and the Advanced Armament Corporation. The Rosco Bloodline 10.5″ 300 Blackout barrel is designed to extract the full potential of the 300 Blackout caliber in a SBR platform in conjunction with a suppressor. Rosco took into account the twist-rate, gas port diameter, and barrel length to bring you a high performance, optimally balanced barrel for your next custom AR build.

Bloodline series barrels are Rosco’s hardest working barrel. No matter if you’re a hobbyist, tactical shooter, or Law Enforcement Officer, Rosco has a barrel that will fit your needs. All of the Bloodline barrels are made from scratch in their Rhode Island facility from a blank piece of steel. The Rosco Manufacturing Bloodline 10.5″ 300 Blackout barrel is machined from 4150 CMV steel, a 1:7 twist, featuring an 11 degree crown, .750 gas block diameter, pistol length gas, and finished in Black Nitride.
