The Spike’s LPK 556 AR-15 lower parts kit is a premium component package designed for builders who want complete customization control. This kit excludes the fire control group intentionally. Therefore, you select your own trigger separately to match your exact performance needs.

Furthermore, the bolt catch assembly with spring and plunger ensures smooth cycling. The magazine catch system comes complete with spring and billet button.
Quality Components for DIY Builds
Moreover, the aluminum trigger guard features a spring-loaded detent for precision engagement. This Spike’s LPK 556 also includes front and rear take-down pins for field stripping. The buffer retainer spring and pin maintain proper bolt carrier movement during firing. An A2 pistol grip with hardware provides secure installation and control.
Finally, all necessary roll pins for bolt catch and trigger guard assembly are included. This kit works seamlessly with 223 Remington and 5.56 NATO ammunition. Indeed, compatibility with standard AR-15 lower receivers is guaranteed. As a result, your build stays on schedule with proven, industry-standard parts.
