The NOXs Billet is to upper receivers what the HMMV is to sport utility vehicles. Designed from the drawing board up as a high performance platform, the manufacturing and features are a wish list for the perfect rifle or carbine.
The upper receiver is CNC machined from a solid billet of 7075-T6 aluminum to Seekins Precision exceptional standards, far exceeding mil-spec requirements. The receiver and included NOXs Hand Guard top rails are seamless, providing monolithic receiver performance and maximum optics and accessory mounting options. Both the receiver and hand guard are Type III Class 2 Hardcoat Anodized matte black.
Extremely lightweight and infinitely adaptable because of the MLOK attachment system, the included NOXs hand guard is perfect for tactical and competition use. Precision machined from 6061-T6 aluminum, it features a seamless top Picatinny rail and MLOK slots at 3, 6 and 9 O’clock positions for solid mounting of accessories where needed.
Combat Billet Uppers come standard with a match grade, stainless steel barrel in .223 Wylde. Unlike conventional upper receivers, the NOXs Billet gas system can be finely tuned for performance and reliability because of the included Seekins Precision Adjustable Gas Block. The gas block and Mid-Length Gas Tube are Melonite coated for reliability and ease of maintenance. Seekins highly effective Melonite coated flash hider is also included.
NOXs Billet uppers are compatible with MIL-SPEC lower receivers and most aftermarket rail systems.

The 2A Armament Full Mass Carrier (FMC) was designed as a high-quality, full mass bolt carrier group, with an emphasis on enhanced weight distribution. By relocating the bulk of carrier mass to the tail, the FMC keeps the firearm in a more balanced state. Weight that would normally be over the magazine well is now over the pistol grip on an AR-15 rifle when at rest. The distribution of weight is further utilized during the firing cycle as the FMC reciprocates along the plane located within the pocket of the shooters shoulder and primary support hand, instead of out in front between the magazine well, and primary support hand. The FMC can give the shooter an extremely reliable full mass bolt carrier group, with a weight distribution advantage over standard carriers on the market.
NOTE: Does not support the use of forward assist. Not compatible with full auto systems
