Precision CNC machined from solid billet 7075-T6 aluminum, the Seekins Precision SP223 Billet Lower is the first step to building the best AR possible. For Seekins Precision, Mil-Spec is just a starting point. Specifically designed for serious tactical shooters, the Seekins Precision SP 223 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, and the trigger reset adjustment screw allows fire control tuning for optimum performance.The quick access mag release and beveled mag well assist with rapid, positive magazine changes and works with most all magazines including Magpul P-Mags and Surefire high capacity magazines.
To assist with exact, no hassle assembly, the rear take down detent has also been relocated under the grip. All of the features and superior design combine to make the SP 223 lower receiver a significant upgrade over common mil-spec lowers.
