The PRO2A 16" 6.8 SPC II 1/10 Mid Length NR Side Charging Melonite M-LOK AR-15 Upper Kit delivers a comprehensive, range-ready platform upgrade designed to maximize intermediate-range terminal power within a standard AR-15 framework.

Key Features
Non-Reciprocating Side Charging Architecture: The manual side charging handle remains completely stationary during active firing cycles, clearing workspace and preventing optic collision.
Optimized Mid-Length Gas Routing: Perfectly tuned to regulate gas velocity and cyclic dwelling time, dramatically softening physical recoil climb while decreasing internal part stress.
Precision 1/10 Twist Stabilizer: Precision button rifling twist profile dialed in to achieve ultimate bullet stabilization across the market's favorite mid-to-heavy grain 6.8 SPC hunting cartridges.
All-In-One Assembly Package: Ships fully configured with a side-charging Nitride Bolt Carrier Group (BCG), free-float M-LOK handguard rail, full lower parts tree, and stock buffer hardware matrix.
