Product Overview

The PRO2A 22" 6.5 Grendel 1/8 Rifle Length Melonite M-LOK AR-15 Upper Kit provides an all-inclusive, high-performance workspace solution tailored to extract maximum ballistic velocity and precision from the 6.5 Grendel cartridge. Featuring a premium 22-inch target barrel length, this configuration burns slower powder profiles with extreme efficiency, yielding minimized wind drift and superb accuracy at extended distances. Outfitted with a dedicated full-auto profile Type II 6.5 Grendel bolt carrier group, standard charging handle, complete lower parts matrix, and a polymer adjustable blade package, it simplifies custom construction by handling all critical tracking and cycling calculations right out of the box.

Key Features

• All-In-One Complete Kit Pipeline: Consolidates your entire shopping list by providing the internal cycling mechanics, fire control group, lower frame small parts, and stabilizing furniture inside one premium assembly order.
• Peak 22-Inch Velocity Barrel: Full 22-inch length maximizes powder burn, pushing projectiles to their optimal kinetic thresholds for superior downrange impact energy and flatter flight metrics.
• Smooth Rifle gas Subsystem: Delivers a dramatically softened recoil signature and minimized internal pressure spikes, optimizing target re-acquisition speed for precise follow-up shots.
• Versatile 1:8 Twist Profile: Standard twist orientation flawlessly stabilizes an abundant range of factory grain options, tracking seamlessly from light target loads up to heavy hunting bullets.
• Liquid QPQ Melonite Preservation: Full-immersion liquid nitriding creates an incredibly slick, hard-wearing surface inside the 4150 CMV steel barrel core to handle sustained friction, gas wear, and humidity.
• Free-Floating M-LOK Handguard: Features a rigid-profile modular rail system aligned flat with the upper receiver top rail, optimizing bipod and accessory placement without shifting your barrel's point of impact.
