6.5 Grendel AR-15 Rifle with 18″ Stainless Steel Heavy Barrel | M-LOK | Magpul MOE QD Bipod

Built for precision, reliability, and extended-range performance, this 6.5 Grendel AR-15 combines quality components from Palmetto State Armory, Bear Creek Arsenal, Magpul, and Amend2 to create a versatile rifle equally at home on the range, in the field, or hunting medium-sized game.

At the heart of this rifle is an 18-inch heavy-profile 416R stainless steel barrel chambered in 6.5 Grendel Type II. The 1:8 twist rate stabilizes today’s most popular hunting and match bullets, while the mid-length gas system provides smooth, dependable cycling. The barrel features industry-standard 5/8×24 muzzle threads, making it compatible with a wide variety of muzzle brakes, flash hiders, and suppressor mounting systems (where legally permitted).

The complete forged upper from Bear Creek Arsenal includes a forged receiver, E9310 bolt, rear charging handle, and a lightweight M-LOK split handguard that provides ample space for accessories while maintaining excellent balance.

The rifle is built on a Palmetto State Armory complete Classic Stealth lower receiver, precision machined from 7075-T6 forged aluminum and finished with a MIL-SPEC Type III hardcoat anodizing. It features a mil-spec receiver extension, M4 adjustable stock, standard carbine buffer system, and a staked castle nut for long-term reliability. This lower is a factory blem model with cosmetic imperfections only; these minor finish variations do not affect function or durability.

For enhanced stability, the rifle includes a Magpul MOE QD Bipod designed specifically for M-LOK handguards. The lightweight polymer and steel construction installs without tools, deploys quickly, adjusts from 7 to 10 inches, and folds into a compact, low-profile package when not in use.

Feeding the rifle is an Amend2 Mod-2 10-round magazine engineered specifically for 6.5 Grendel and 6mm ARC cartridges. Its proprietary internal geometry, anti-tilt follower, and stainless steel spring provide dependable feeding and exceptional durability.
