DETAILS:
.300 Blackout is a very capable round with a heavier projectile that is extremely effective for those who use AR-15s for hunting big games at shorter ranges. It also has all the stopping power you need for a self-defense caliber. If you would like to build an AR-15 chambered in .300 Blackout, you should check out the Radian Model 1 Complete Upper (9-inch Barrel .300 Blackout). It includes an upper receiver, a bolt carrier group, a charging handle, a gas system, a handguard, and a barrel that are all made to work together to provide an accurate, reliable, and smooth-shooting rifle.
