Product Description

The Luth-AR Builder Lower Parts Kit is designed to help complete an AR-15 “mil-spec” lower receiver build while leaving key performance and preference items up to you. This kit provides the essential small parts needed for assembly, but intentionally excludes the fire control group (trigger components) and pistol grip so you can choose your own. Luth-AR uses American-made components produced to mil-spec drawings with quality materials and heat treat processes, and the springs are made from a combination of 17-4 stainless steel and certified mil-spec steel wire.

Product Highlights

  • AR-15 builder lower parts kit for completing a stripped lower while customizing trigger and grip choices
  • No metal injection molded (MIM) parts—components are investment cast and/or machined to mil-spec drawings
  • Includes core lower-receiver small parts such as bolt catch parts, selector parts, takedown/pivot pins, detents, and springs
  • Springs manufactured from 17-4 stainless steel and certified mil-spec steel wire for reliable function
