Daniel Defense OEM Mil-Spec AR-15 6-Position Collapsible Buttstock - Brown

From Daniel Defense, the OEM Mil-Spec Collapsible Buttstock is a brown synthetic stock engineered for a precise, rattle-free fit on any Mil-Spec receiver extension (buffer tube) on AR-15, M16, and M4 platform rifles. This is the buttstock only, and the buffer tube is not included.

Molded from glass-reinforced polymer in a brown finish, the OEM stock offers a classic look that pairs well with brown furniture sets and custom rifle builds. The collapsible design provides six positions of length-of-pull adjustment, allowing the shooter to dial in a comfortable cheek weld and consistent eye alignment with iron sights or optics across different body sizes, plate carriers, or layered kit.

Featuring no integrated accessory rails, the OEM keeps the rifle's lines clean and snag-free for sling work, shoulder transitions, and tight shooting positions. Whether replacing a worn factory stock or finishing a complete custom rifle around a Mil-Spec tube, this is a direct-fit AR-platform upgrade that matches the rest of Daniel Defense's lineup of Mil-Spec components.
