Seekins Precision NOXs 10.5" 300 BLACKOUT Billet Complete Upper AR15 Pistol 300BLK or Built to Rifle with Appropriate SBR License

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 10.5" Upper comes standard with a match grade barrel in .300 BLK. Unlike conventional upper receivers, the NOXs™ Billet gas system can be fine 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. Includes Strike Industries Enhanced Charging Handle.
