Description

The Strike Industries Enhanced AR-15 Lower Parts Kit 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 is called the Builders Kit as it includes all the essential parts needed to complete your build. It does not include the pistol grip or mil-spec trigger parts because we understand that builders may want to include a pistol grip or drop-in trigger of their own choice.Below you’ll find a complete breakdown of all the parts this kit comes with including our Strike Enhanced parts which provide better looks and higher function than an average LPK.
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.
