PRO2A 24" 22 ARC 1/7 Rifle Length NR Side Charging Melonite M-LOK AR-15 Upper

Product Description

Squeeze every single foot-per-second of velocity potential out of Hornady's advanced cartridge while unlocking unparalleled flat-shooting consistency on long-range small-frame builds, elevated with elite modern manual control ergonomics. The PRO2A 24" 22 ARC Rifle Length NR Side Charging Melonite M-LOK Upper Assembly represents the absolute pinnacle of long-range varmint and precision target tracking layout design. Shifting away from a traditional rear charging configuration, it implements a left-side non-reciprocating charging handle that remains completely stationary while live rounds cycle, preserving absolute shooting safety and protecting the operator's forward support hand grip. Constructed around a premium billet aluminum receiver with a right-side ejection layout, this complete upper receiver houses an extended 24-inch 4150 CMV heavy profile barrel. The aggressive 1:7 twist rate provides immaculate rotational stabilization for long, heavy, high-BC bullets over extreme distances under intense crosswinds. Operating on a tuned rifle-length gas system to ensure highly regulated gas pressures, optimal dwell times, and soft, uniform mechanical tracking, this turnkey system slides seamlessly onto your standard AR-15 lower receiver setup to complete your ultimate target or hunting weapon.

Key Features

Non-Reciprocating Side Charging Action: Intuitively positioned on the left side of the receiver, this mechanism lets you cycle the bolt while keeping your hand secure on the main pistol grip, staying completely fixed during live cycling to prevent handguard interference or sight-picture disruption.
Extended 24-Inch Velocity Scaling: Extracts absolute maximum energy and complete powder burn from the 22 ARC cartridge, yielding flat downrange trajectories over extreme distances.
Aggressive 1:7 Fast Twist Performance: Engineered explicitly to flawlessly stabilize high-BC heavy match ammunition profiles for reliable downrange tracking.
Regulated Rifle-Length Gas Cycling: Softens operating pressure curves and dampens bolt carrier impact speed, providing a linear recoil pulse and prolonging component life.
Liquid Bath Nitride Protection: Full interior and exterior QPQ Melonite barrel coating provides maximum resistance to heat friction, extreme weather elements, and throat erosion.
