The skeletonized 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 M-LOK attachment system, the included NOXs™ hand guard is perfect for tactical and competition use. Precision machined from 6061-T6 aluminum, it features a top Picatinny rail and M-LOK slots at 3, 6 and 9 O’clock positions for solid mounting of accessories where needed.
The NX complete uppers 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 Gas Tube are Melonite coated for reliability and ease of maintenance. Seekins highly effective Melonite coated Rook Flash Hider is also included.
NX15 uppers are compatible with Mil-Spec lower receivers and most aftermarket rail systems.
