These complete uppers have been assembled and test fired. They are ready to ship and are plug and play. These uppers are built with a 14.5” barrel that highlights precision accuracy over other brands. We pin and weld a Dead Air (keymount) muzzle device to make the barrel a legal 16” rifle length and ready for your suppressor. Simply snap this beauty onto your lower of choice and enjoy high performance that you can trust at an affordable price.

(OPTIONAL MUZZLE DEVICES CAN BE PIN & WELDED ON REQUEST)

Our billet uppers are made from 7075-T6 aluminum. CNC machined featuring a very sleek profile. These uppers are impressively built to sustain heavy abuse.

 

The upper receiver is paired with a 13” 6061-T6 CNC machined billet handguard. The MLOK handguard features superior tensile strength and is designed to endure heavy impact without throwing your iron sights or optic out of alignment. The handguard mates direct to the upper and features anti-rotational tabs. The handguard is installed using our steel low profile barrel nut which requires no timing as it fits under the gas system.

 

The 14.5" lightweight barrel is produced from raw bar stock to finished product. The barrel is properly stress relieved after rifling, and extensions are torqued after nitride. Superior quality control system ensures that all barrels are dimensionally correct and bores fall well within their individual tolerance.

Features a Dead Air "KEYMO" Key mount Muzzle Device for key mount suppressors.

Features Breek Arms Gas Buster Charging Handle for reducing gas blowback to the operator when running supressed.

The Superlative Arms Patented Bleed Off® Mode, direct impingement, gas block for the AR-15 platform adjusts the gas flow by bleeding the gas out the front of the block instead of restricting the flow like conventional adjustable blocks.

• The pressure used in the block is reduced only to the amount required to drive the bolt carrier. The remaining gas and pressure are bled out of the block allowing the system to run much cleaner and cooler.
• Reduction of wear on the bolt carrier group components and upper receiver.
• Reduction of felt recoil allowing for faster follow-up shots.
• Patented adjustment detent is located outside of the block and therefore no contamination.
• In Bleed Off Mode the gas adjustment screw does not restrict the gas flow; therefore, there is no erosion or seizing of the screw, and no loss of detent due to carbon build up. Although it is removable, we have added a safety mechanism, which stops you from unintentionally backing the screw all the way out.
• When using SBR’s and/or suppressors the Bleed Off port allows the excessive pressure to be exhausted out of the block reducing blow back

Features our ambidextrous charging handle made from 7075-T6 billet aluminum and milled to spec. A milspec forward assist and dust cover are also installed.
