DPMS DA-15 Lower Receiver Foundation

The DPMS DA-15 lower receiver is forged from 7075-T6 aluminum and finished with mil-spec hardcoat anodize. The multi-cal marking means it's compatible with any standard AR-15 caliber upper. This is a serialized component, so it arrives as the registered firearm in this kit. The receiver uses standard mil-spec dimensions throughout, so any mil-spec upper will fit without modification.

Davidson Defense Match Grade Lower Parts Kit

The included 31-piece lower parts kit is Davidson Defense Match Grade quality. It features a skeletonized straight trigger shoe with a 3.5 lb pull weight, which is clean and responsive without being overly refined. All components are steel with black oxide finish for durability. This is a complete parts kit, meaning every internal component you need for the lower is included and ready to assemble.

Adjustable Carbine Stock and Buffer System

The carbine buffer system uses a mil-spec 6-position adjustable stock in polymer, allowing you to dial in the length of pull you need. The stock integrates sling attachment points for quick mounting of tactical slings or single-point attachments. The buffer system includes a standard 3 oz carbine buffer, mil-spec recoil spring, heavy-duty carbine buffer tube, receiver end plate, and castle nut. This is a complete, functional carbine-length setup ready to cycle.
