PRO2A 7.75" 308 Win 1/10 Pistol Length Melonite M-LOK AR-10 Upper

Product Description

Pack the incredible concrete-smashing impact of the standard .308 Winchester round into an ultra-short Personal Defense Weapon (PDW) blueprint. The PRO2A 7.75" 308 Win Pistol Length Upper Assembly is engineered precisely to maximize hard-hitting fire parameters out of a heavily compact profile. Built on a heavy-duty forged 7075-T6 aluminum DPMS-pattern upper receiver block with standard right-side ejection mechanics, this system centers around a 7.75-inch medium profile barrel. The 1:10 twist rate guarantees robust rotational stabilization for standard 147gr to 168gr factory loads out of an ultra-abbreviated bore footprint. Tuned with a micro-pressure pistol gas system and a low-profile gas block, it provides reliable cycling dynamics. The rigid 7-inch free-float aluminum handguard extends flush with the muzzle threads, yielding a streamlined setup that drops seamlessly onto your DPMS-profile lower receiver configuration.

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.

Why Choose This Product?

Running a standard rifle cartridge out of an ultra-short 7.75-inch barrel configuration traditionally presents severe gas dwell time and cycling hurdles on the large-frame AR-10 platform. Pro2A Tactical resolves this directly by pairing a precision-machined pistol gas layout with matching high-pressure DPMS components. This configuration delivers an incredibly compact, dependable big-bore weapon package that slides perfectly onto your existing lower receiver block.
