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

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 without component matching guesswork. The PRO2A 24" 22 ARC Rifle Length Melonite M-LOK Upper Kit provides an all-inclusive rifle completion package engineered explicitly to maximize the hyper-velocity attributes and high ballistic coefficients of Hornady's 22 Advanced Rifle Cartridge (ARC). Constructed on a premium forged 7075-T6 aluminum receiver with tight right-side ejection configuration margins, this system centers around an extended 24-inch 4150 CMV heavy barrel. The aggressive 1:7 twist rate provides immaculate rotational stabilization for long, heavy, high-BC bullets under intense crosswinds. Tuned with a smooth rifle-length direct impingement gas layout and a low-profile gas block to regulate bolt carrier speed, this turn-key platform arrives completely paired with a matching type 2 bolt carrier group, full lower parts conversion kit, and an adjustable stock assembly. Drop these components into your standard stripped lower receiver to finish your ultimate target or hunting weapon.

Key Features

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 internal 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.
Turn-Key Rifle Build Setup: No piecemeal component tracking required; arrives complete with a full lower parts kit, mil-spec fire control group, and a standard adjustable rifle stock assembly.

Why Choose This Product?

The 22 ARC pushes standard small-frame performance metrics out to extreme distance thresholds, but extracting its true potential requires maximum barrel length to secure a complete powder burn.

This premium, American-made assembly delivers elite mechanical consistency and exceptional precision right out of the box.
