Luth Ar Llc AR-15 Lower Receiver Parts Builder Kit

The LRPK-BLDR Lower Receiver Parts Builder Kit from Luth-AR is ideal for anyone assembling an AR-15 who needs all the small components to complete a stripped lower, but wants to customize performance-critical parts. You provide your own trigger/fire control components, pistol grip, buttstock/buffer system, and triggerguard — Luth-AR’s Builder Kit covers everything else.

No need to buy all these standard parts separately and risk missing one. This kit includes:

• Buffer Retainer & Buffer Retainer Spring
• Safety Selector Lever + Detent
• Selector/Ejector Spring
• Bolt Catch + Spring, Plunger & Roll Pin
• Magazine Catch
• Magazine Release Button (Aluminum)
• Front Pivot Pin
• Rear Takedown Pin
• 2x Takedown/Pivot Pin Detents
• 2x Detent Springs
• 2x Hammer/Trigger Pins
• Mag Catch/Buttstock Plunger Spring (1 ea.)

All components are standard AR-15 parts designed to fit mil-spec lower receivers. Most lowers on the market today are compatible with these parts. If you’ve built an AR-15 before, installation will be straightforward.
