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.
