Product Description


The UX-15 upper is manufactured from billet 7075-T6511 aluminum to ensure rigidity while showing off our patented skeletonized technology. This design greatly reduces weight and mitigates gas blowback to the shooter's face in suppressed applications. Our UX-15 Upper is compatible to most MIL-SPEC lowers on the market. Milled into the UX-15 upper are large cuts, as well as a larger ejection port capable of discharging casings from cartridges up to .458 / .50 caliber. All individual uppers are finished in black anodized.

    The highly skeletonized upper was paired with a Faxon Match series 16” pencil, Rise 140 3.5lb trigger, JAG composites hand guard,, Leupold 1-4 LPVO, an Odin adjustable gas block and Low mass BCG. The upper mated perfectly with a skeletonized lower and even at 4 1/2 lbs will shoot 1/2” group (sometimes fractionally better). Excellent upper.
