PRODUCT DESCRIPTION
The 3KEYZ Tactical Wethrin 16″ 6.5 Grendel Complete Upper is crafted for shooters who demand precision, power, and versatility. Equipped with a 16″ 4150 CMV H-bar barrel with a nitride finish and a 1:8 twist rate, this upper delivers excellent stabilization for long-range 6.5 Grendel rounds. The carbine gas system paired with a low-profile .750″ gas block ensures reliable cycling across loads. Built on a lightweight yet rigid 7075-T6 anodized upper receiver, it features a free-float M-LOK handguard for maximum modularity. Rounding out the build is a 6.5 Grendel II QPQ nitride BCG, Mil-Spec charging handle, and a standard 5/8×24 threaded GI birdcage flash hider — all drop-in ready for fast deployment.
