Luth-AR 308 Lower Parts Kit, Builder, Fits AR-10, No Fire Control Group or Grip

Description

The Luth-AR 308 Builder Lower Parts Kit gives you the lower hardware you need to finish an AR-10 or 308 AR build without paying for a fire control group or pistol grip you plan to replace. Luth-AR uses no MIM parts in any of their kits, and because of this, every part in the builder kit comes from investment casting or machining to Mil-Spec drawings with proper materials and heat treatment. As a result, this luth-ar lower parts kit gives builders a higher-quality starting point than most budget kits that use cheaper MIM components for the small parts.

In addition, Luth-AR makes all parts in the United States so the kit meets American manufacturing standards from raw material to finished part. Furthermore, the springs use 17-4 SST and certified Mil-Spec steel wire, which gives them more consistent tension and longer service life than standard wire springs. Also, skipping the fire control group and grip saves you money upfront if you already have an aftermarket trigger and grip picked out for the build. Moreover, every part goes through Mil-Spec heat treatment so the components stay within spec through thousands of rounds and years of use. When you build a 308 AR and want a luth-ar lower parts kit without the parts you’ll swap out anyway, the builder kit is the one to grab.

However, this kit does not include the fire control group or pistol grip. Therefore, source those separately before you complete your lower build.
