The PRO2A LEFT HAND 12.5" 6.5 Grendel 1/8 Carbine Length NR Side Charging Melonite M-LOK AR-15 Upper Kit balances mid-to-long-range ballistic dominance with optimized southpaw ergonomics in a highly agile footprint. Built around a precision 12.5-inch 4150 CMV steel barrel chambered for Type II 6.5 Grendel, this complete conversion package transitions a standard frame into a flat-shooting, high-energy tactical build. Engineered with a premium mirrored left-ejecting Non-Reciprocating (NR) side-charging handle, this system gives left-dominant shooters smooth manual control without standard rear charging disruptions or facial debris blowback. This range-ready conversion package includes the left-handed bolt carrier group, full lower parts tree, and buffer tube assembly equipment.
