300BLK Barrel Options

300BLK Barrel Options

Rainier Arms maintains a ready supply of the best 300BLK barrels available. 300 Blackout (aka 300 Blackout or 300 AAC Blackout) is probably the best cartridge available for shooting suppressed. In fact, maximizing the potential of subsonic ammunition is one of the greatest advantages of a blackout barrel of any barrel length - though the ballistics of the 300 BLK are a solid plus+ as well. 

That's another advantage of 300 AAC Blackout - it not only performs very well in a shorter barrel, it actually does better in a shorter barrel (particularly if the platform has been suppressed). This trait makes it ideal for short barreled rifle (or the AR pistol, though that's now defunct). The round still delivers plenty of energy with a longer barrel, as evidenced by the great success it has seen in the hunting world. 

Several quality brands of 300 BLK barrel are available at Rainier Arms, including RA's own brand, Ballistic Advantage, Faxon Firearms, V Seven Weapon Systems, and others. We also have a variety of 300 BLK ammo. (Effectiveness of each type depends on velocity, weight, etc., but we provide ballistic coefficient where available.)

Note: Although intended for use with a suppressor, 300 blackout ammo does not consist solely of subsonic loads. Supersonic ammunition is available as well. It's just not as quiet when you're using supersonic loads instead of subsonic rounds.
