Palmetto State Armory has generously donated a 8.5″ Pistol Length .300 AAC Blackout AR-15 upper to the Marty Brown Memorial™ events. If you’ve ever thought about getting an AR-15 upper in .300 AAC Blackout, here is your opportunity (just be aware that a 8.5″ upper will make your AR-15 subject to federal NFA regulations and you will need to plan accordingly). .300 AAC Blackout has become a popular cartridge due to it’s ability to be loaded for both subsonic and supersonic bullet velocities.
