PRO2A 8.5" 7.62x39 1/10 Pistol Length NR Side Charging Melonite M-LOK AR-15 Upper

Product Description

Pack the severe close-quarters impact and deep terminal fragmentation of the standard 7.62x39mm cartridge into an exceptionally compact, agile platform while completely elevating your manual weapon manipulation controls. The PRO2A 8.5" 7.62x39 Pistol Length Non-Reciprocating (NR) Side Charging Melonite M-LOK Upper Assembly introduces an advanced manual layout that relocates cycling to a smooth left-side handle. This non-reciprocating lever remains completely stationary while live rounds cycle, preserving absolute shooting safety and protecting the operator's forward support hand grip. Please Note: This configuration is shipped as an Upper Receiver Only and DOES NOT include a Bolt Carrier Group (BCG), making it the perfect choice for builders who already own a compatible 7.62x39 bolt system or want to select their own custom carrier mass. Constructed around a premium billet aluminum receiver with a standard right-side ejection port setup, this configuration features a rigid 8.5-inch 4150 CMV medium profile barrel with a versatile 1:10 twist rate. Fine-tuned with a reliable direct impingement pistol-length gas layout and a low-profile gas block to handle cyclic pressure curves safely, this turn-key platform comes wrapped inside a rigid 7-inch free-float aluminum handguard and drops seamlessly onto your standard AR-15 lower receiver setup.

Key Features

• Upper Receiver: Maximizes component customization flexibility and cuts down on build costs if you already own a 7.62x39mm bolt carrier group.
• Non-Reciprocating Side Charging Action: Intuitively positioned on the left side of the receiver, this mechanism lets you cycle the bolt while keeping your hand secure on the main pistol grip, staying completely fixed during live cycling to prevent handguard interference or sight-picture disruption.
• Devastating 8.5-Inch Big-Bore Firepower: Delivers massive intermediate rifle-caliber kinetic signatures from a highly maneuverable layout, serving as a premier personal defense weapon configuration.
• Tuned Pistol-Length Gas Curve: Optimizes internal gas expansion velocity and dwell times to deliver flat, uniform mechanical cycling profiles with a wide variety of factory intermediate ammunition.
• Liquid Bath Nitride Protection: Full interior and exterior QPQ Melonite barrel coating provides maximum resistance to heat friction, extreme weather elements, and throat erosion.
