Product Description

Experience massive big-bore power in a complete, all-in-one package. The PRO2A 8.5" .458 SOCOM Upper Build Kit with Flash Can includes everything you need to drop onto your stripped lower receiver. Built around a precision 4150 CMV Melonite barrel and a specialized wide-ejection port receiver, this package integrates a custom blast-forward Flash Can muzzle device.

Key Features

Blast-Forward Flash Can: Pre-installed extended linear flash director projects aggressive muzzle blast and concussive noise away from the operator.
Widened Ejection Port: Engineered with an enlarged port cutout to effortlessly clear massive .458 SOCOM casings, stopping stovepipe failures before they happen.
Reliable Big-Bore BCG: Includes a premium, high-strength Bolt Carrier Group properly spec'd and headspaced with a bolt face optimized for single-stack big-bore extraction.
All-Inclusive Lower & Brace Kit: Comes paired with a standard Mil-Spec lower parts kit and a high-durability pistol brace setup to complete your pistol lower build.
Hand-Polished Single Feed Ramp: Modded single large feed-ramp geometry limits friction and ensures heavy-grain round stacks seat smoothly into the chamber.
