The PRO2A 22" 5.56 NATO 1/7 Rifle Length NR Side Charging Melonite M-LOK AR-15 Upper introduces an advanced ergonomic and long-range ballistic solution for target shooters, varmint hunters, and competitors. Moving away from standard rear-charging handle layouts, this premium upper configuration features a fluid, Non-Reciprocating (NR) side-charging handle mechanism. Paired with a full 22-inch premium steel barrel, this complete assembly maximizes internal velocity potential to deliver flatter trajectories, increased downrange energy, and consistent sub-MOA precision groupings across extended ranges.

Traditional rear charging handles force marksmen to break their cheek weld and drop out of their optical plane just to manipulate the bolt. The PRO2A 22" Side Charging Upper eliminates this tactical compromise entirely, providing a fluid side-charging configuration that lets you cycle the action comfortably while staying completely locked onto your downrange target.
While shorter 16-inch configurations lose valuable velocity and trajectory stability over deep distances, this extended 22-inch Melonite barrel ensures a complete powder burn, squeezing premium velocity metrics out of your ammunition. Backed by a rifle-length gas system that expands the dwell time to yield a remarkably soft recoil impulse, this assembly delivers an uncompromised precision upgrade built to dominate target lines and long-range varmint environments straight out of the box.
