Texas Black Rifle Company Complete Upper Receiver Group

All Upper Receiver Groups, as well as Complete Weapon Systems use an upper receiver precision machined to correct Mil-Specs from 7075 T6 Forgings and are finished in the best Type III Hard Coat Anodizing available. They also come standard with Ballistic Advantage barrels. The BA 300 Blackout chambered Barrel is machined from 4150 Chrome Moly Vanadium steel with a QPQ (Black Nitride) Corrosion Resistant Finish and QPQ coated M4 feed ramp extension. This barrel is a 16” Government Profile with a 1:7” twist rate, pistol length gas system for versatility, and comes with a 1MOA accuracy guarantee. The barrel extension has M4 feed ramps allowing for more reliable feeding. This Upper Receiver Group comes with a TBRCi 15” Lightweight M-Lok Handguard. M-Lok is a modular design allowing the user to have picatinny rails exactly where he needs them and nowhere he doesn’t. This feature allows the handguard to maintain a slim profile and light weight without sacrificing strength or durability. The TBRCi Bolt Carrier Group is finished in the same QPQ/Nitride finish as the barrels. This finish is slicker than the standard parkerized finish and makes cleaning your BCG easier. The bolt undergoes MPI (Magnetic Particle Inspection) testing. The Bolt Carrier is an M16 style, otherwise known as a full auto style, carrier. This design has more weight and has a fully shrouded firing pin. The slightly heavier mass of the M16 BCG delays the bolt unlocking by a few milliseconds, this allows pressures to decrease in the chamber, gives a smoother feel and less felt recoil. This BCG comes with a properly staked gas key. TBRCi Upper Receiver Groups come standard with A2 flash hider, low profile gas block and standard charging handle. This complete Upper Receiver Group is ready to be slapped onto your custom lower receiver to complete your AR15 build!
