Key Features

• Forged 7075‑T6 aluminum construction — aircraft‑grade strength and stiffness for a durable, lightweight multi‑caliber lower.
• Mil‑spec dimensions & tight tolerances ensure correct component interface and reliable fit with aftermarket parts.
• Black hard‑coat anodized finish for long‑lasting corrosion resistance and a tactical, low‑glare appearance.
• Designed as a stripped M5 lower for AR‑10/AR‑308 builds; ideal starting point for custom big‑bore rifles.
• Integrated trigger guard for a clean, snag‑free profile and reduced parts count during assembly.
• Threaded rear takedown pin detent hole (4‑40 set screw) — improved retention and a neater finish vs. open detent holes.
• Bolt catch threaded for a screw pin (no roll pin required) — simplifies install and increases serviceability.
• Selector markings compatible with 45°, 60° or 90° throws for flexible selector choices and ergonomic setups.
• No grip gap design — fits common aftermarket pistol grips cleanly without gaps or need for shimming.
• Includes Nylon‑tipped tensioning set screw for receiver fitment tuning and eliminating play.
• DPMS .308 component compatibility — works with standard DPMS pattern parts and magazines for broad accessory support.
• Stripped‑lower format lets builders pick their preferred lower parts kit, buffer, and stock to complete the rifle.
