PRO2A 20" 22 ARC 1/7 Rifle Length NR Side Charging Melonite M-LOK AR-15 Upper Kit

Product Description

Unlock extreme high-velocity thresholds, ultra-flat trajectories, and match-grade precision out of a standard small-frame platform without individual component matching guesswork. The PRO2A 20" 22 ARC Rifle Length NR Side Charging 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) while upgrading your operational economics. Shifting away from a traditional rear charging design, it implements a left-side non-reciprocating side charging handle layout that remains completely stationary while live rounds cycle, preserving absolute shooting safety and protecting the operator's forward hand grip. Configured on a premium billet aluminum receiver with a right-side ejection layout, this setup houses a premium 20-inch 4150 CMV barrel. The aggressive 1:7 twist rate provides immaculate rotational stabilization for long, heavy, low-drag 22-caliber projectiles favored in long-range precision disciplines. Operating on a tuned rifle-length gas system to ensure highly regulated gas pressures, optimal dwell times, and soft mechanical tracking, this turn-key platform arrives completely paired with a matching side-charge 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 an elite precision long-range tool.

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.
• Elongated 20-Inch Ballistic Mastery: Maximizes complete powder burn efficiency for the 22 ARC cartridge, yielding an absolute velocity premium over shorter barrels to flatten far-reaching trajectories.
• Aggressive 1:7 Fast Twist Performance: Engineered explicitly to flawlessly stabilize high-BC heavy match ammunition profiles under intense downrange crosswind conditions.
• Regulated Rifle-Length Gas Cycling: Softens operating pressure curves and dampens bolt carrier impact speed, providing a linear recoil pulse and prolonging component life.
• Turn-Key Rifle Build Setup: No piecemeal component tracking required; arrives complete with a non-reciprocating side-charge upper assembly, type 2 side-charge bolt carrier group, full lower parts kit, fire control trigger group, and a standard adjustable rifle stock assembly.

Why Choose This Product?

The 22 ARC turns the standard small-frame AR-15 platform into a legitimate 1,000-yard competitor, but adjusting your weapon configuration shouldn't force you to break your cheek weld or target focus. Pro2A Tactical removes precision construction variables by providing a fully matched side-charging upper block, an internal Melonite core barrel, a high-pressure type 2 bolt carrier group, and an all-inclusive rifle-length stock bundle in one cohesive package. This premium, American-made assembly delivers elite ergonomic handling, flat paths, and superior field reliability right out of the box.
