300 Blackout Uppers, Rifles, Pistols & More

Why 300 Blackout? Once considered an exotic round, 300 Blackout ammo has become a household caliber. One of the best ways to shoot 300 Blackout is suppressed. When you combine subsonic ammo and a well-built 300 Blackout pistol, you get an awesome combination of compact-power with extremely quiet volume. 300 Blackout is also a round commonly used for hunting as well.
