Strike Industries Enhanced Lower Parts Kit Details:

The Enhanced Lower parts kit offers a convenient upgrade package for the AR-15 for those looking for a complete Strike Industries solution for new builds, or to update their plain jane AR.  This kit includes all the basics that you will need to build out your AR (minus grip), but with Strike Industries Enhanced lower parts where applicable.

This complete kit includes our fire control group which offers a crisp 4.5-5.5 lb pull, with unmatched smoothness for mil-spec style AR-15 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.
