Match Grade 10″ .300 Blackout Barrel by Seekins Precision
When you bring an upgrade as serious as a match grade barrel into your life it bears some consideration. I know, even a safety selector is important, but a high-end barrel is much more so. When you take a closer look at a Seekins Precision 300 blackout barrel, you will find custom touches usually found on much higher priced barrels. Seekins chose to use 1:7 5R button rifling in your new 10.5 inch 300 blackout barrel for a good reason. First, a 1:7 twist is the optimum rate of twist for heavier bullets fired from shorter barrels. This is perfect for a .300 blackout because it loves the heavier ammunition.
The 5R designation stands for the five ridges incorporated in the barrels’ rifling. It may sound like a small thing, however, it is not. The use of five ridges instead of the standard six means that no area of the bullet is compressed on its direct opposite side. This more concentric design results in less bullet deformity, therefore, a more spherical and accurate bullet.
