The Radian Weapons Model 1 AR-15 Upper with 15.5 inch M-LOK Handguard in Black (brand part no. R0193) pairs Radian’s precision-machined upper receiver with a free-float hand guard built for a clean, snag-free rail line. Radian Weapons builds its uppers to tight tolerances for consistent bolt-carrier fit and reliable cycling, and the M-LOK slots along the 15.5 inch hand guard give a shooter room to mount lights, grips, and other accessories exactly where needed. It’s a drop-in upgrade for shooters building a precision or duty-grade AR-15 upper.
