The Luth-AR .308 lower parts kit is a builder's kit for .308 / AR-10 lower receivers. It covers the small parts you need to finish a .308 lower: bolt catch, magazine catch, takedown and pivot pins, detents, springs and the buffer retainer. It does not include the fire control group, so you can pair it with the trigger you want.

Parts have a matte black finish and use Luth-AR part numbers, so you can match each piece to the list below during assembly.
