Want an AR upper that's as lightweight as possible, while retaining the most rail estate possible? Looking for the most accurate, well-built AR capable of shooting subsonic suppressed and supersonic with one gas system and barrel? If that sounds expensive, you're wrong. You've found the perfect AR upper: Our 300 Blackout Rifle Upper with 16" barrel and 15" lightweight Keymod handguard. This upper provides the most rail length with the least weight possible, and its profile, capability, and reliability make this AR upper look like it belongs on a SEAL's SOPMOD.

Made in The USA

Sure, a lot of rifle parts are built in the states, but our 300 Blackout Rifle Upper is head and shoulders above the rest. Every upper assembly features an all-mil-spec construction: 4150 Chromoly Steel barrel, M4 feed ramps, standard Flat Top M4 upper receiver, Keymod and Picatinny rail attachments, Type III Hard Coat Anodized finish, and the expectation of providing 1-MOA accuracy at 100 meters if you're good enough.

The beauty of the black rifle lies in the paperwork - only the stripped lower receiver is considered the firearm.

Just rip out of the box and slap it on your 80 lower project or any finished AR lower and you're ready to roll.
