PRO2A 20" 308 Win 1/10 Rifle Length Melonite M-LOK AR-10 Upper

Product Description

The PRO2A 20" 308 Win Rifle Length Melonite M-LOK AR-10 Upper Receiver Assembly delivers structural stability and exceptional long-range distance accuracy. Engineered on a forged heavy-duty DPMS-compatible upper receiver pattern, this system incorporates a true rifle-length direct impingement gas setup to optimize system dwell time and soften internal mechanical recoil profiles. Perfectly matching premium manufacturing with modular tactical real estate, it drops cleanly onto corresponding AR-10 lowers for a reliable high-power platform conversion.

NOTE: MUST BE PAIRED with our Pro2A Tactical Stripped or Complete AR-10 Lower Receivers for seemless compatibility and trouble free fitment. As there is NO milspec standard for the AR-10 Platform, we do not guarantee fitment with other manufacturer's AR-10 Lower Receivers.

Key Features

Extended Long-Range Performance: 20-inch barrel footprint maximizes powder burn efficiencies to squeeze optimal velocities out of heavy duty 308 Winchester loads.
Rifle-Length Gas Dynamics: Provides an optimized gas-port distance to significantly drop carrier slide velocities, lessening cyclical wear and softening perceived shoulder impact.
DPMS Platform Compliance: Machined to the universally popular DPMS Low or High profile specification standards for streamlined adaptation across standard modern lower blocks.
Premium Melonite Lining: 4150 CMV steel is thoroughly liquid nitrided to secure supreme environmental protection, uniform thermal dispersion, and extended throat longevity.

Why Choose This Product?

This premium 20-inch AR-10 assembly takes the guesswork out of building a flat-shooting tactical or hunting marksman rifle. By combining an optimal 1/10 twist barrel layout that perfectly stabilizes standard match projectiles with a dedicated soft-cycling rifle length gas block system, it mitigates the snappy recoil common to heavy-bore semi-automatics. Built with high-durability components inside a modular, free-floating shell, it offers precision builders an exceptionally tough, modular foundation for extended range operations.
