Rosco Purebred 10.5″ 300 Blackout Barrel

This Rosco Purebred 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 precision 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.

Rosco Manufacturing’s “Purebred” series is a testament to precision and quality manufacturing. We took a step back to see how we could create a barrel line that would be a culmination of all the lessons learned through years of making barrels for several OEM’s. The result is a barrel that will produce results out of the box for any shooter that is looking to take their skills above and beyond. All of our Purebred barrels are made from scratch in our Rhode Island facility and start life as a blank piece of 416R stainless steel.

Arm or Ally is proud to add Rosco Manufacturing to our wide selection of AR Barrels from Ballistic Advantage and Faxon. If you just starting to build your own custom rifle, see our growing selection of AR parts, to include receivers, bolt carrier groups, muzzle devices, and more in our AR parts department. Are you a reloader, or considering becoming one? We offer a large selection of bullets and brass to choose from.
