Precision CNC machined from solid billet 7075-T6 aluminum, the SP223 Billet Lower is the first step to building the best AR15 possible. Mil-Spec is just a starting point for Seekins Precision. Specifically designed for serious tactical shooters, the SP223 has features not found on standard AR lower receivers that significantly improve handling and performance. The Seekins Precision Enhanced Bolt Catch comes standard on the SP223. Shooters can easily drop the bolt from either side with our ambi-bolt release feature. Custom screw in dowel pins are used to secure these components, eliminating the use of roll pins, hammers, and pin punches for installation.
An oversized winter trigger guard allows the use of gloves while maintaining precise trigger control. The quick access mag release and beveled mag well assist with rapid, positive magazine changes and works with most magazines including Magpul P-Mags (excluding the D-60 and Surefire high capacity magazines).
All of the features and superior design combine to make the SP223 lower receiver a significant upgrade over common Mil-Spec lowers.
