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.
NOXs™ Billet come standard with a match grade 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 Rook Flash Hider is also included.
