Build the ultimate straight-walled hunting pistol or defensive platform with the PRO2A 12.5" 350 Legend Pistol Length Upper Kit with Flash Can. This comprehensive, components package provides premium, high-tolerance parts designed to transform any standard mil-spec lower receiver into a functional powerhouse. Featuring a highly maneuverable 12.5-inch Melonite-treated barrel, a linear blast forwarding flash can tucked under a free-float M-LOK handguard, a full lower parts kit, and a pistol stabilizing blade buffer assembly, this complete kit ensures maximum control, reliable cycling, and reduced side concussion on the bench or in the field.
Key Features
- Linear Blast-Forward Flash Can: Directs aggressive side-concussion and unburnt powder forward and away from the shooter—essential for short-barreled straight-walled platforms.
- All-In-One Complete Build Bundle: Eliminates tracking down individual accessories by packing the upper setup, lower components kit, and stabilizing buffer layout in a single box.
- Premium Pistol Blade Setup: Includes an ergonomic stabilizing blade brace designed to provide reliable leverage, recoil management, and repeatable indexing.
- Melonite (QPQ) Hardened Core Finish: Provides a diamond-hard, low-friction surface inside the bore and chamber to enhance feeding reliability, corrosion resistance, and total operational life.
- Full Mil-Spec Lower Parts Kit: Built from heavy-duty, heat-treated domestic components to guarantee a clean, reliable trigger break and crisp system resets.
- Compact 12.5-Inch Maneuverability: Yields a perfectly balanced profile that navigates thick woods, tight ground blinds, or vehicle configurations with ease compared to standard 16-inch setups.

Why Choose the Pro2A Tactical 12.5" 350 Legend Flash Can Kit?
Devastating Compact Power with Direct Concussion Control
The .350 Legend cartridge offers incredible energy metrics within straight-walled hunting restriction zones, but short barrels can create substantial blast pressure. The integration of a recessed forward flash can solves this, throwing the noise and muzzle blast entirely downrange. This makes it a far more comfortable configuration when shooting alongside others, clearing close environments, or targeting from inside tight blinds.
