This 300 Blackout upper kit starts with an AR-15 MILSPEC 7075 T6 Forged Aluminum receiver, mated to a Hitman Industries 5 inch 300 Blackout, Micro Length Gas System, 1:7 Twist, Nitride/Melonite treated barrel. Hitman Industries is one of our major partners in the industry and they produce high quality, accurate barrels. The Axis Rail is a free floated system, M-LOK slots on all three sides, full length picatinny rail at the top, lightweight handguard. Barrel Nut is made out of solid steel to ensure a solid mounting system.
Comes with the Bolt Carrier Group and Standard Charging Handle. Also included is a lower parts kit and stabilizing fin/blade kit to turn your stripped lower receiver into a full pistol.
**Upper has shorter handguard to allow suppressors to be easily attached to the barrel**
SB Tactical SBA3 Adjustable Brace is OPTIONAL. Features a minimalist design, integral and ambidextrous QD Sling socket and capable of accepting milspec carbine buffer tube extensions.
We can also UPGRADE the GAS BLOCK to an Adjustable Gas Block. Great option if you are using a suppressor or just want to fine tune your system.
We can also UPGRADE the TRIGGER to a Rise Armament RAVE 140 or a Timney Impact Trigger. Great option if you are looking for a lighter and more crisp trigger pull.
Also an OPTION is COLOR. We can change the receiver and handguard to FDE (FLAT DARK EARTH) COLOR (see pictures).
We also offer an OPTION to add a 80% 7075 T6 Aluminum Milspec Lower Receiver (Raw or Anodized) to your kit.
We also offer a CHOICE of Muzzle Devices - upgrade the flash hider to a Black or Stainless Competition Muzzle Brake. This is an enhanced version of the popular style muzzle brakes. The baffles and ports are milled larger to drive pressure up and to keep the muzzle down more effectively.
