Overview
Cross Machine Tool machines the UPUR-2 from 7075-T6 billet and removes the forward-assist housing while retaining both the shell deflector and a machined dust-cover port. The 8.2-ounce receiver has M4 feed ramps, engraved T-marks, a flat-top 1913 rail, and a Type III Class 2 hardcoat finish.
CMT lists compatibility with standard parts, mil-spec lowers, and most aftermarket handguards. That makes the UPUR-2 a less radical slick-side choice than CMT's UPUR-3, which also deletes the shell deflector and dust-cover provision.
