The Strike Industries Enhanced AR-15 Complete Lower Parts Kits offers a convenient upgrade package for the AR15 and those looking for a complete Strike solution for new builds, or to update their plain jane AR. This kit includes all the essentials that you'll need to build out your AR (minus the pistol grip).

This complete kit includes our fire control group which offers a crisp 5.5-8.5 lb pull, with unmatched smoothness for mil-spec style AR15 triggers. Longitudinally ground and polished sear engagement surfaces coupled with precision cut sear angle equate a vastly improved trigger feel without sacrificing safety or reliability.

With our Strike Enhanced parts you're getting better aesthetics and performance than the average LPK.
PACKAGE CONTENTS: SI ENHANCED LOWER PARTS
  • Enhanced Bolt Catch - features improved grip surfaces and angles
  • Strike Magazine Catch
  • Strike Magazine Catch Button
  • Enhanced Pivot Pin - longer of the two large pins.
  • Enhanced Takedown Pin - smaller of the two large pins.
  • SI Selector Lever - 2 included in package
  • SI Selector End Plate
  • SI 60-90° 3-in-1 Selector Shaft - with screws
PACKAGE CONTENTS: SPRINGS
  • Bolt Catch Spring - easily confused with the disconnector spring; disconnector spring is tapered though.
  • Buffer Retainer Spring - second largest coil type spring in the kit.
  • Disconnector Spring slightly larger than bolt catch spring, identifiable because one end is a little bit wide than the other.
  • Hammer Spring - largest of all the springs.
  • Magazine Catch Spring - this is the largest coil spring in the kit.
  • Pivot Detent Spring - same as the takedown detent spring, so there are two in a kit.
  • Selector Spring - similar to the takedown and pivot detent springs, but larger diameter; there will only be one of these.
