    CORE15 300 Blackout Uppers

    Core 15 is proud to introduce our new series of 300 Blackout Uppers!
    Since its SAAMI approval in January of 2011, the 300 Blackout has spread rapidly throughout the AR market. Utilizing the same upper, lower, bolt, and magazine as an AR15 in .223/5.56mm, the 300 Blackout is the perfect solution for a well needed 30 caliber compact semi-auto rifle that is extremely versatile.
    Core 15 has answered the demands for this compact 30 cal. rifle by offering three different variations of our current production upper receivers that are equipped to handle the 300 Blackout.
    Subsonic and supersonic rounds are available from Remington and a few other ammunition manufacturers.

    Looks good. What I'm most looking forward to is someone producing mock dissipator style 300BLK upper, with carbine or pistol gas and a FSB mounted further out to use with mid-length handguards.

    Looks like some high-quality barrels. I'm pretty excited about this caliber. Can't wait to get started on my 300BLK build for whitetail and wild boar.
    I was going to think of a clever signature, but then I took an arrow to the knee.
