The Alexander Arms Tactical Complete Upper (brand part number UTA65) delivers a ready-to-run 6.5 Grendel AR-15 upper with a 16-inch barrel and a black Cerakote-finished aluminum receiver. Alexander Arms, the company that developed the 6.5 Grendel cartridge, builds this upper around a 1:8-inch twist rate suited to the mid-weight to heavier bullets that make Grendel an efficient mid-range hunting and precision cartridge. An M-LOK handguard gives builders slim, modern accessory mounting, and the upper ships optic-ready with no iron sights included. As a complete upper, it drops onto a compatible AR-15 lower to add 6.5 Grendel capability to an existing rifle without a full custom build.
