PRODUCT DESCRIPTION
The 3KEYZ Tactical Roughneck 12.5″ 6.5 Grendel Pistol Upper delivers long-range performance in a compact, carbine-gas package. Built with a 12.5″ medium-profile 4150 CrMoV barrel at a 1:8 twist, it's optimized for 6.5 Grendel accuracy and efficiency. The carbine-length gas system paired with a micro low-profile 0.750" gas block ensures consistent cycling. A durable free-float M-LOK handguard provides plenty of real estate for accessories, while the “Panhead” billet upper receiver and 9310-alloy QPQ nitride BCG round out a high-end complete upper. Includes a Pershing-style flash can and Mil-Spec charging handle — drop-in ready for your build.
