Revolutionize your rifle configuration with the PRO2A 16" 5.56 NATO 1/7 NR Side Charging Melonite M-LOK AR-15 Upper with Flash Can. This premium, factory-assembled complete upper receiver matches ergonomics with advanced muzzle management.

Key Features
- Non-Reciprocating Side Charging Architecture: Elite Gibbz Arms handle mechanism remains completely static during active fire loops, keeping optics clear and generating mechanical lever advantages during reloads.
- Blast-Forwarding Linear Flash Can: Directs muzzle noise, hot gases, and high brightness forward downrange, providing an excellent upgrade for shooter acoustics when clearing structures or indoor lanes.
- Premium Melonite / Nitride Treated Barrel: Constructed from 4150 Chrome Moly Vanadium steel and treated completely with liquid QPQ Nitride/Melonite to reinforce the bore layout against erosion and heat spikes.
- Versatile 1:7 Twist Stabilization: Offers a rapid button rifling sequence optimized to deliver tight accuracy matrices with heavy duty projectiles (62gr to 77gr) while managing standard 55gr weights.
- Slim 17" Free-Float M-LOK Handguard: Supplies an uninterrupted top rail layout and extensive M-LOK attachment walls, allowing flush positioning of lights, tape switches, or backup sights around the flash can perimeter.
- Tested & Ready Assembly: Arrives headspaced, tested, assembled and ready to go.

Why Choose the PRO2A 16" 5.56 NATO Side Charging Flash Can Upper?
Standard right-hand charging configurations force operators to drop their visual layout or cheek weld when clearing manual feed errors. The Pro2A Tactical Non-Reciprocating Side Charger solves this by placing tactical manipulation on the left side, keeping your workspace fast and modern. By packing this structural upgrade alongside a linear blast-forwarding flash can, Pro2A removes the aggressive acoustic punch associated with traditional 5.56 muzzle devices. Backed by a match-ready Melonite barrel loop and complete factory test-firing, this upper receiver group presents an ergonomic, smooth-cycling, and quiet solution built for serious training or home defense setups.
