DPMS DA-15 Lower Receiver

The DPMS DA-15 is a forged 7075-T6 aluminum lower receiver marked for multi-caliber use. The black hardcoat anodizing meets MIL-A-8625 Type III Class 2 specifications, which means it's built to military durability standards. The receiver uses standard AR-15 pattern magazine wells and buffer extension interfaces, so compatibility with mil-spec uppers and components is assured. This is a serialized component, so it's the legal receiver that requires proper documentation.

Davidson Defense Match Grade Lower Parts Kit

The kit includes 31 precision-machined components designed to deliver a consistent trigger break and smooth operation. The Match Grade designation means tighter tolerances than standard mil-spec parts. The straight trigger shoe is skeletonized, reducing weight and providing a clean, uncluttered feel. All fire control group components, including the hammer, disconnector, and selector, are included and ready to install. The Gen 2 generation reflects refinements in machining and material selection over earlier versions.

FDE M4-Style Adjustable Carbine Stock

The buttstock is reinforced polymer in Flat Dark Earth, a color that works across tactical and hunting applications. The 6-position adjustment lever uses spring-loaded mechanics for solid locking at each position. The textured non-slip buttplate provides purchase in various shooting scenarios, and the integrated sling loop supports standard two-point sling attachment. The low-profile ergonomic design keeps weight minimal while maintaining structural integrity. This stock drops in on any mil-spec carbine buffer tube.
