Description

The Pro2A Tactical 5.5-inch 10mm Auto Non-Reciprocating (NR) Side Charging Complete Upper Kit with Flash Can delivers ultimate tactical agility, advanced blast routing, and immense stopping power to the AR-10mm platform. Hand-assembled and quality verified in Georgia, this premium conversion package features an advanced static side-charging mechanism and a linear muzzle device designed to drive concussive energy downrange. Arriving complete with a matched side-charging blowback bolt group, full lower parts kit, and an optimized heavy buffer stock assembly, it takes the guesswork out of building a hard-hitting defense platform.

Key Features

Non-Reciprocating Control: Features an advanced side-charging upper receiver with a handle that remains fully static while cycling, preventing optics mount interference and yielding maximum manual leverage.
Forward Concussion Redirection: Outfitted with a slimline aluminum linear Flash Can muzzle device that channels noise, flash, and concussive pressure away from the operator.
Turnkey Conversion Bundle: Simplifies sourcing by packaging a fully populated side-charging upper receiver group, tucked flash can, matched blowback BCG, complete lower parts kit (LPK) with fire control group, and a full stock assembly.
Aggressive Tucked Aesthetic: The linear flash can sits partially shrouded beneath the free-floating 7-inch M-LOK handguard, maximizing rail accessory space while establishing a flush profile.

Why Choose This Product?

Harnessing the raw kinetic power of the 10mm Auto cartridge in a micro platform typically results in intense side-blast, handling complications, and component matching headaches. The Pro2A 5.5" 10mm NR Side Charging Upper Kit with Flash Can solves these limitations completely by grouping a factory-headspaced nitrided side-charging bolt group with a forward-directing muzzle layout and an optimized heavy-weight buffer system to control recoil smoothly. Featuring a revised feed cone geometry that handles heavy hard-cast wilderness ammunition and defensive hollow points natively, this kit strips away common configuration headaches. It is the definitive choice for personal defense and backcountry operators seeking a premium, flat-shooting weapon system built all in one package.
