Announcing a new partnership with Rosco Manufacturing. Rosco Manufacturing is an American manufacturer of hard-use precision rifle barrels.  We are currently selling Rosco Manufacturing’s American made bloodline rifle barrels on our website.

Here is a breakdown of the Rosco Manufacturing’s American made bloodline rifle barrels we will be selling:

Bloodline 300 Blackout Barrels

Rosco Mfg’s 300 Black Out barrels were created by using input from SOCOM end users and some of the original creators of the 300 Blackout caliber. Every barrel was designed to optimize the original role for this caliber; to be suppressor friendly and accurate. It is their goal to get you the performance that you seek out of these barrels when running sub-sonic ammo or supersonic ammo (depending on barrel length). Twist rates, gas port diameters, and lengths have all been taken into account when we set out to make these. Let’s just say that Rosco Mfg doesn’t like leaving things to chance.  Specs:
