Enhancements:
- URX6 Handguard
- The URX 6 is an advanced, self-indexing handguard designed for exceptional shift resistance. It features a full-length 12:00 MIL-STD 1913 interface rail complemented by seven sides of M-LOK negative space mounting slots. This handguard seamlessly slides over the attached barrel nut, with precision alignment facilitated by an anti-rotation index tab and slot mechanism integrated into the top rail of the upper receiver. The anti-rotation and alignment elements are sleek and unobtrusive, eliminating any external snag or catch points. The handguard is secured by a robust retention nut that exerts considerable force at the attachment point, ensuring maximum stability and resistance to impact-induced shift.
- E3.2 Bolt
- The E3 bolt, famed for its extraordinary robustness and functionality, leaves little room for enhancement. Its radiused lugs and reduced diameter cam pin hole render it the most durable AR-pattern bolt known to date. The dual-spring extractor, featuring improved leverage, adeptly resolves extractor durability and operational issues commonly encountered with short-barreled carbines. The E3.2 bolt directly addresses the nuances of ejection performance, particularly when employing a suppressor on a short-barreled carbine. Dual ejectors considerably mitigate wear and prolong lifespan compared to the legacy single ejector, delivering sustained ejection force to the case head due to strategic ejector placement. A vibration-dampening o-ring works synergistically with the extractor, ensuring a constant and positive force of the extractor claw against the case rim throughout the extraction and ejection processes. Furthermore, stress relief features incorporated into the lugs significantly extend the service life, while a hard chrome coating resists fouling accumulation, thereby simplifying the cleaning process.
Reduced Profile Charging Handle Latches
- The included ambidextrous charging handle has undergone a refinement with reduced lever lengths by .016” (4mm) to mitigate the risk of inadvertent snagging or activation. Despite their abbreviated design, the medium-length latches retain ease of accessibility, ensuring seamless operation even when wearing gloves.
