Traditional right-handed firearms ruin a left-handed shooter's focus by spraying hot gas, debris, and abrasive particles straight across their field of view. The PRO2A Left Hand 18" Side Charging Upper eliminates these operational compromises completely. By changing the manual manipulation point to a stationary, non-reciprocating left-side handle, you can charge your platform fluidly without breaking your cheek weld or pulling your focus off your primary optic. Stepping up to an 18-inch Melonite barrel maximizes the ballistic velocity of your ammunition, yielding an excellent trajectory path for medium-to-long-range applications. Backed by a smooth mid-length gas system that cushions cycling force and softens felt recoil, this complete receiver assembly delivers a clean, reliable, and uncompromised tactical solution straight out of the box.
