BHA Precision AR-15 16" 6mm ARC, 15" MLOK Handguard, Black Complete Upper Receiver w/ BCG & CH

Stretch your AR‑15’s capability into precision centerfire territory with the BHA Precision 16" 6mm ARC Complete Upper — a purpose-built, drop‑in solution that turns a standard lower into a true long‑range performer. Built around a precision 16.0" barrel chambered in the efficient and flat‑shooting 6mm ARC, this upper blends long‑range velocity, consistent tracking, and controllable recoil into a lightweight, shootable package.

The slim 15" free‑float M‑LOK handguard gives you clean ergonomics and plentiful real estate for optics, bipods, and mission accessories while keeping the profile snag‑free. The barrel is finished for durability and stability under extended strings of fire, and the mid‑length gas system smooths the gas impulse for better recoil management and component longevity. BHA assembles and function‑tests a matched Bolt Carrier Group (BCG) and Charging Handle (CH) before shipment — this unit arrives drop‑in ready so you can mount an optic, zero, and shoot.

Whether you’re building a prairie dog rig, a precision carbine for PRS-style fun, or a versatile patrol/field rifle that needs to reach out past standard 5.56 distances, the 6mm ARC upper provides a compelling mix of ballistics, modularity, and real‑world practicality.
