DPMS DA-15 Lower Receiver Quality

The DPMS DA-15 lower receiver is machined from 7075-T6 forged aluminum and finished with black hardcoat anodize per MIL-A-8625 Type III Class 2 specification. This forging process creates a lower receiver with consistent strength and dimensional accuracy. The multi-caliber marking allows compatibility with standard AR-15 upper assemblies regardless of caliber. The lower receiver includes standard mil-spec magazine well and buffer tube interface dimensions, ensuring compatibility with any mil-spec upper assembly.

Adaptive Tactical EX Performance Stock Configuration

The Adaptive Tactical EX Performance stock is a collapsible carbine buttstock that adjusts across six positions on the mil-spec buffer tube. The stock is constructed from glass-filled polymer and includes a QD sling mount and sling loop for attachment options. The adjustable design allows customization of length of pull to match shooter preference and body dimensions. The stock seats firmly on the buffer tube without rattling and provides a clean interface with the receiver extension.
