Why the 300 Blackout?

  If you are looking for an effective home defense weapon or a powerful hunting rifle, the 300 Blackout AR15 takes your AR to another level. The standard 5.56 NATO round does not provide the knockdown power the 300 Blackout offers.  Upgrading to the 300 Blackout will give you the extra power you need while still using the same magazine and bolt of your traditional AR-15 rifle. The 300 Blackout ammunition gives you the best of both worlds by meshing a heavy .30 caliber round with the effectiveness and versatility of the AR-15 platform.  300 Blackout is very effective as a hunting round, add a silencer and sub-sonic rounds and you have a quiet efficient killing machine.  MÔS-Tek is also pleased to be one of only a few manufacturers that offer a 1:5 Twist rate in the 300 Blackout.  Perfect for Sub-sonic shooters the 300 Blackout 1:5 Twist has the high speed and bullet expanding power to take down anything that happens to wander into your scope crosshairs…bummer for them!
