PRO2A 5.5" 10mm 1/16 Pistol Caliber NR Side Charging Melonite M-LOK Upper with Flash Can

Description

The Pro2A Tactical 5.5-inch 10mm Auto Non-Reciprocating (NR) Side Charging Complete Upper Receiver assembly featuring an integrated linear Flash Can delivers exceptional blast mitigation and high-power performance in a hyper-portable platform. Carefully hand-assembled and quality verified in Georgia, this system replaces the traditional rear charging handle with an advanced, static side-charger mechanism. Paired with a linear flash can that pushes the massive concussive force of full-power 10mm loads downrange, this drop-in setup offers an ultra-clean, tucked aesthetic built for close-quarters handling, vehicle deployment, or back-country defense.

Key Features

• Non-Reciprocating Control: Features a side-charging layout with a handle that remains entirely static while cycling, preventing optic mount interference and maximizing mechanical leverage.
• Forward Concussion Redirection: Outfitted with a slimline aluminum linear Flash Can muzzle device that channels loud noise, flash, and concussive pressure away from the operator.
• Straight Blowback Simplicity: Operates completely without gas blocks or gas tubes, dropping complex wear points to guarantee steady feeding and extraction cycles with heavy loads.
• Aggressive Tucked Design: The linear flash can sits partially shrouded beneath the free-floating M-LOK rail system, maximizing rail accessory space while establishing a flush silhouette.

Why Choose This Product?

Building an ultra-short 10mm AR platform often introduces severe side-concussion and limited optics clearance. The Pro2A 5.5" 10mm NR Side Charging Upper with Flash Can solves these layout limitations entirely by pairing an advanced non-reciprocating handle with a forward-directing muzzle configuration. Built inside a tough billet receiver with a heavy-duty nitride bolt carrier group, it features an enhanced feed cone that reliably cycles heavy hard-cast trail rounds and high-expansion defensive ammunition alike. It is the premium drop-in evolution standard AR operators look for when outfitting a serious, compact 10mm defensive build.
