The Daniel Defense Collapsible Mil-Spec Stock for AR-15/LR-308 carbines delivers the fit and control that serious shooters demand. Built from a proprietary blend of glass-infused polymers with soft-touch rubber overmolding at key contact points, this buttstock is engineered to work with Mil-Spec receiver extensions—the standard you'll find on most modern AR platforms. Unlike cheaper alternatives that rattle or shift, the DD stock is precision-formed to minimize forward and lateral play, so you get a solid, repeatable cheek weld without needing a separate tensioning device or friction lock.

Comfort and modularity go hand-in-hand here. The stock ships with two interchangeable butt pads sized for different body armor, gear setups, and shooter preference: a thicker convex pad (0.8") and a thinner concave pad (0.5"). Run both, swap them, or ditch them entirely—the choice is yours. The concave design helps prevent snagging when you're shouldering the rifle, which matters whether you're on the range, in a training course, or working tactically. Limited-rotation QD swivel attachment points on both sides let you rig an ambidextrous sling without fumbling.

This is the kind of no-nonsense upgrade that doesn't compromise durability or ergonomics. If you're running a Mil-Spec AR-15 or LR-308 and your current stock feels loose or uncomfortable, a quality Daniel Defense replacement tightens up your platform and gives you options that budget stocks simply don't.

Frequently Asked Questions

Will this stock fit my AR-15?

Yes, if your rifle has a Mil-Spec diameter receiver extension. The Daniel Defense stock is designed specifically for Mil-Spec extensions, which are the standard on most AR-15 and LR-308 platforms. If you're unsure about your receiver extension diameter, check your rifle's spec sheet or contact us.

What's the difference between the two included butt pads?

The stock comes with a thicker convex pad (0.8") and a thinner concave pad (0.5"). The thicker pad suits shooters with less body armor or gear; the thinner, concave pad is designed for operators wearing heavier plate carriers or tactical vests. The concave shape also helps prevent snagging when shouldering. You can swap them or run the stock without either pad to fit your specific loadout.

Does this stock eliminate rattle or wobble?

Yes. The Daniel Defense stock is precision-formed to fit Mil-Spec receiver extensions with minimal forward or lateral play, eliminating the common looseness found in cheaper alternatives. You won't need a separate friction lock or tensioning device—the engineered fit does the job.

Can I attach a sling to this stock?

Yes. The stock features ambidextrous limited-rotation QD (quick-detach) swivel attachment points on both sides, letting you run a sling setup of your choice without extra hardware.
