Unlock the perfect balance of velocity, compact geometry, and mirroring southpaw ergonomics. The PRO2A Left Hand 12.5" 300 Blackout Pistol Length Non-Reciprocating (NR) Side Charging Upper Assembly with Flash Can completely modernizes manual operation by moving cycling to a heavy-duty, left-side cocking lever. Built specifically for left-handed shooters, the mirrored left-ejection port layout completely shields your line of sight from fly brass and escaping gases, while the non-reciprocating handle stays stationary to prevent optical blockages. Built around a versatile 12.5-inch barrel configuration, it secures full powder burns for supersonic rounds while remaining highly efficient with heavy sub-sonic ammo. Pre-equipped with a slimline tactical flash can muzzle device, it forces intense gas concussion and flash straight downrange away from the operator. Drops natively onto any standard Mil-Spec AR-15 lower receiver configured as a legal pistol or registered SBR. Proudly 100% designed, machined, and precision-assembled in the USA.

Southpaw marksmen building an agile, highly adaptable defensive weapon choose this setup. The side-charging billet design seals the traditional rear handle opening, completely blocking blowback gas and powder flecks from leaking into your face when running suppressed or high-concussion configurations.
Operators training inside confined environments or indoor lanes select this flash-can-equipped upper. It channels the aggressive acoustic concussion of the 12.5" barrel completely forward and away from adjacent lane operators, minimizing uncomfortably loud side-blast feedback.
