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

Product Description

Maximize your velocity scaling, terminal energy retention, and side-charging operation ergonomics with the PRO2A 18" 6.8 SPC II Mid Length NR Side Charging Upper Assembly. Re-engineered to bypass traditional rear-charging constraints, this system relies on a left-side non-reciprocating handle layout that remains completely stationary while live rounds cycle, protecting the operator's forward hand grip. Built around a precision billet aluminum receiver block with a standard right-side ejection configuration, 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. Encased inside a rigid 15-inch free-float aluminum handguard, this upper drops seamlessly onto your standard lower receiver block to build a high-performance hunting rifle.

Key Features

• Non-Reciprocating Side Charging Handle: Left-side charging mechanism permits fast bolt operation while keeping your hand secure on the grip, remaining entirely static when live cycling.
• Optimized 18-Inch Muzzle Velocities: Elongated barrel structure burns intermediate 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.
• Resilient Free-Float M-LOK Architecture: Premium 15-inch slim profile aluminum rail isolates the barrel from external handling pressure vectors, ensuring continuous point-of-impact accuracy.
• Liquid Bath Nitride Hardening: The 4150 Chrome Moly Vanadium steel core features full interior and exterior QPQ Melonite coating to offer absolute weatherproofing and prolonged bore precision.

Why Choose This Product?

Shifting your intermediate rifle platform to a non-reciprocating side charger completely changes the manual of arms, granting bolt-manipulation access without breaking your cheek weld or target focus. Pro2A Tactical pairs this high-speed manipulation with an elongated 18-inch Spec II hunting core, delivering an American-made upper assembly optimized for downrange knockdown consistency and elite field performance.
