Daniel Defense OEM Mil-Spec Brown Synthetic Stock for AR-Platform (Receiver Extension Tube Not Included)

The Daniel Defense OEM Mil-Spec Brown Synthetic Stock is a precision-engineered buttstock built for AR-platform rifles that demand rock-solid repeatability and clean aesthetics. Constructed from a proprietary blend of glass-filled polymers with strategically placed soft-touch rubber overmolding, this collapsible stock is engineered to fit standard Mil-Spec diameter receiver extensions with minimal play—no tensioning devices or friction locks needed. Whether you're running a duty rifle, a precision build, or a versatile hunting setup, this stock delivers the consistent cheek weld and control serious shooters expect from Daniel Defense.

The real flexibility shows in the butt pad options. You get two pads included—a thicker convex shape measuring 0.8" and a thinner concave shape at 0.5"—so you can dial in the perfect fit for whatever body armor, jacket, or gear you're wearing that day. Don't want a pad at all? Run it bare. The concave design also prevents snagging when you shoulder the rifle quickly, a detail that matters in dynamic shooting. The brown synthetic finish looks sharp and handles hard use without vanity.

Ambidextrous shooters will appreciate the limited-rotation QD swivel attachment points molded into both sides of the stock, making it easy to run a two-point sling exactly the way you want it. This is a no-nonsense accessory that prioritizes function, durability, and precision fit over marketing noise—exactly what you'd expect from Daniel Defense. Note: receiver extension tube is not included; ensure you have the proper Mil-Spec tube before ordering.
