CM15 6.5 Grendel 16″ Upper: Long-Range Precision, Lightweight Platform

Unlock the true potential of the AR-15 with the CM15 6.5 Grendel 16″ Upper. Designed for the marksman who wants to push past the limitations of the standard 5.56 NATO, the 6.5 Grendel offers superior ballistics, higher energy retention, and impressive accuracy at distances up to 800 yards—all while remaining in a lightweight, non-NFA rifle configuration.

Superior Ballistics for Hunting and Competition

The 16-inch barrel is the ideal “all-around” length for the 6.5 Grendel. It provides the necessary velocity to fully stabilize high-BC projectiles, making it a favorite for deer and hog hunters who need more “knock-down” power than a .223 can provide. The mid-length gas system ensures a smooth recoil impulse, allowing for faster follow-up shots and better target tracking through your optic.

Customized for Your Discipline

Whether you’re building a precision target rig or a mountain-ready hunting rifle, our customizable options have you covered. Select from various M-LOK handguards for easy bipod and tripod mounting, or upgrade to a Type 2 Bolt Carrier Group (BCG) specifically engineered for the unique demands of the Grendel casing.

Key Features:

• 16″ Match-Grade Barrel: 4150 CMV steel with a 1:8 twist for heavy projectile stability.

• Caliber: 6.5 Grendel (Type 2).

• Extended Reach: Exceptional terminal ballistics for medium game at 200+ yards.

• Universal Fit: Drops onto any standard AR-15 lower (utilizes 6.5 Grendel-specific magazines).

The CM15 16″ 6.5 Grendel Upper is the ultimate multi-role upgrade, turning your carbine into a precision long-range tool.
