Magpul MAG325-FDE MOE/CTR Cheek Riser 0.25" - Flat Dark Earth for MOE/CTR Stocks
Magpul
The Diamondback DB15 6.5 Grendel rifle is a mid-length platform built for shooters who want precision and reach without stepping up to a full-length caliber. At 18 inches with an 1:8 twist, this AR-pattern rifle handles the 6.5 Grendel's ballistics with authority—ideal for medium-range hunting, precision rifle competition, or anyone exploring what this cartridge can do. The forged aluminum upper and lower are built solid, the mid-length gas system keeps recoil manageable, and the whole package ships with both a 26-round and 5-round magazine so you're ready to go whether you're running drills or hunting in restricted-mag territory.
The ergonomics are straightforward and user-friendly. You get a Magpul CTR stock (fully adjustable for length of pull and cheek rest), a Magpul MOE K2 grip, and a 15-inch M-Lok handguard with anti-slip texture pads—modern, comfortable controls that won't have you fiddling with your gun. The upper is an A3 flattop with no sights installed, so you have freedom to run your optic of choice. A mil-spec carrier and quality CNC flash hider complete the foundation; this isn't stripped-down budget hardware, but purpose-built gear.
At 9.1 pounds unloaded and collapsing to 38 inches, it balances portability with a real 18-inch barrel. The 6.5 Grendel round splits the difference between 5.56 and .308—inherently accurate, efficient, and capable without the recoil or ammo costs of larger magnums. Diamondback's Black Gold lower adds visual interest and doesn't change function, but it signals that attention's been paid to detail.
This is a rifle for the shooter who knows what he wants: a cartridge and a platform that work together, controls that actually fit your hand, and no surprises. Whether you're building a truck gun, a precision rifle, or exploring intermediate calibers, the DB15 in 6.5 Grendel is honest, capable, and ready.

Yes. The 6.5 Grendel was designed for medium-game hunting and precision shooting. The 18-inch barrel is short enough for rough terrain or vehicle work while retaining enough velocity for effective range. Magazine capacity (26 rounds available) and the flat-shooting ballistics make it practical for hunting scenarios where followup shots matter.
The rifle ships with an A3 flattop upper and no iron sights, so you'll want to mount an optic if you plan to shoot. The flat picatinny top gives you full freedom to choose—red dot, LPVO, scope, whatever suits your mission. If you prefer irons, you'll need to add them separately.
This model includes both a 26-round and a 5-round magazine. The 26-round is standard for 6.5 Grendel; the 5-round is useful in states or hunting zones with magazine capacity restrictions.
The 6.5 Grendel is an intermediate cartridge—more powerful and longer-range than 5.56 NATO but with less recoil and lower ammo cost than .308 Winchester. It's inherently accurate, efficient, and a solid choice if you want something between those two extremes for hunting or precision rifle work.
