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.

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.
