PRO2A 16" 6.8 SPC II 1/10 Mid Length NR Side Charging Melonite M-LOK AR-15 Upper

Product Overview

The PRO2A 16" 6.8 SPC II 1/10 Mid Length NR Side Charging Melonite M-LOK AR-15 Upper introduces enhanced ergonomics and high-performance hunting capabilities to your standard AR-15 footprint. Built around a precision 16-inch barrel chambered in the powerful 6.8 SPC II cartridge, this assembly easily bridges the gap between traditional intermediate calibers and heavy-recoiling large frames. Incorporating an premium Non-Reciprocating (NR) side-charging receiver, it gives shooters a fast, natural manual configuration loop that bypasses standard rear handle limitations and ensures clear structural clearance under large-rimmed variable hunting optics.

Key Features

Non-Reciprocating Side Charging Billet Receiver: The side charging handle remains entirely stationary during cycling sequences, protecting close-quarter clearances and keeping grease away from your face.
Heavy-Duty Melonite Barrel Finish: Premium QPQ Nitride treatment maximizes bore rigidity, extends overall throat life, and delivers excellent weather immunity in damp outdoor environments.
Balanced Mid-Length Gas Layout: Perfectly regulates gas velocity to decrease bolt carrier wear, soften the physical recoil impulse, and ensure flawless extraction sequences.
Precision 1/10 Twist Rate: Precision-stabilized rifling dialed in to deliver exceptional accuracy with mid-to-heavy hunting projectile weights for excellent lethal groupings on medium game.
Slim Free-Float M-LOK Rail System: Delivers an uninterrupted top Picatinny footprint and deep accessory real estate while isolating the barrel to maintain consistent structural harmonics.
