The Luth-AR lower parts builder kit supplies the small parts needed to finish a .308 / AR-10-pattern lower receiver, in a builder configuration that leaves out the fire-control group. You supply your own trigger, hammer, and disconnector, which lets you choose the fire-control group you want.

Features:

• .308 / AR-10-pattern lower parts kit
• Fire-control group NOT included — supply your own trigger, hammer, and disconnector
• Includes trigger guard, magazine catch, and bolt catch
• Includes safety selector
• Includes takedown and pivot pins
• Includes the associated springs and detents

AR-10 / .308 lowers come in different patterns — confirm whether your receiver is DPMS or Armalite pattern before ordering to ensure correct fit.
