(No reviews yet) Write a Review


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 our HADES 2 muzzle device to make the barrel a legal 16” rifle length. Simply snap this beauty onto your lower of choice and enjoy high performance that you can trust at an affordable price.


Our billet uppers are also 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" 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.

Our HADES 2 Muzzle Device is made in house and is a hybrid compensator by design. The HADES provides some of the best performance on the market and has up to a 90% reduction of muzzle rise and muzzle sway while reducing felt recoil to a point of non-existence. The Gen2 HADES is patterned to reduce gas blowback while keeping the volume at an acceptable level on high pressure cartridges. Muzzle Device is pinned & welded in place.


The .750 adjustable gas block is machined from 4140 pre-hardened steel with H&M Black Nitride coating. The gas tube is machined from seamless stainless steel tubing. As always you have comfort that even the smaller parts are USA Made.


The charging handle is made from 6061-T6 barstock and milled to spec. A milspec forward assist and dust cover are installed.
