ROSCO BL BBL 16″ 300BLK HB 1/8

This Rosco 16″ 300 Blackout (300 BLK) barrel is perfect for carbine shooters who plan to use only supersonic ammo or are building a well-balanced hunting setup. Rosco 300 Blackout barrels were designed with input from SOCOM end users and some of the original creators of the 300 Blackout caliber. Each barrel was made to optimize the original purpose of this caliber: being suppressor-friendly and accurate. Rosco aims to deliver the performance you want with these barrels, whether running subsonic or supersonic ammo, depending on the barrel length. When creating these barrels, factors like twist rates, gas port diameters, and lengths were carefully considered. Rosco prefers not to leave anything to chance.
