PRO2A LEFT HAND 18" 6.8 SPC II 1/11 Mid Length NR Side Charging Melonite M-LOK AR-15 Upper Kit

Product Description

Maximize your velocity scaling, terminal energy retention, and side-charging operation ergonomics with the PRO2A LEFT HAND 18" 6.8 SPC II Mid Length NR Side Charging Upper Kit. Explicitly engineered to bypass traditional rear-charging constraints and right-hand ejection facial blowback, this specialized platform centers on an uncompromised manual of arms for southpaw operators. The left-side non-reciprocating handle design remains completely static while live rounds cycle, protecting the operator's support hand grip and allowing bolt indexing without breaking cheek weld. Built around a premium mirrored billet aluminum receiver block with a dedicated left-hand ejection port setup, this platform features an 18-inch 4150 CMV medium profile barrel. The 1:11 twist rate and Spec II chambering combine to safely handle standard factory hunting loads with minimized pressure margins, while a smooth direct impingement mid-length gas setup ensures a soft cycling stroke. Combined with an all-inclusive lower receiver build group and stock assembly, this turnkey kit transforms your standard stripped lower receiver into an elite southpaw deer or hog tracking rifle.

Key Features

• True Left-Hand Ejection Architecture: Dedicated mirrored port layout channels spent casings, visual debris, and harsh gas blowback cleanly out to the left side and completely away from a left-handed operator's face.
• Non-Reciprocating Side Charging Action: Left-side charging mechanism permits lightning-fast bolt manual manipulation while keeping your hand secure on the main pistol grip, remaining entirely stationary when live cycling.
• Optimized 18-Inch Muzzle Energies: Elongated barrel structure burns intermediate hunting powders completely, yielding a distinct velocity premium over shorter configurations to flatten downrange trajectories.
• Proven SPEC II Performance Chambering: Configured natively to manage the higher pressures of modern 6.8mm hunting variants safely with predictable headspace metrics.
• Turn-Key Rifle Build Setup: Features a complete lower parts kit and a standard adjustable rifle stock assembly—eliminating the headache of sourcing piecemeal southpaw components.

Why Choose This Product?

Shifting your intermediate rifle platform to a true left-ejecting, non-reciprocating side charger completely modernizes ergonomics, granting southpaw shooters lightning-fast clearing options without losing a pristine sight picture. Pro2A Tactical pairs this high-speed manipulation layout with an elongated 18-inch Spec II hunting core and an all-inclusive rifle-length stock build bundle. This complete, American-made assembly delivers smooth ergonomic handling and heavy downrange energy in a package that eliminates the standard gas hazards and cross-body casing flight lines for southpaw shooters.
