Luth-AR Lower Parts Builder Kit, No Grip, No Trigger LRPK-BLDR

The LLRPK-BLDR Lower Receiver Parts Builder Kit from Luth-AR is ideal for anybody assembling an AR-15 who needs all the small bits-n-pieces to complete a stripped lower, but who wants to customize the performance-critical components. You supply the trigger/fire control components, pistol grip, buttstock/buffer system, and triggerguard of your choice. Luth-AR’s Builder Kit covers everything else. No need to purchase all these commodity parts separately, only to sit down on a weekend to do your project...and find out your missing one or more small bits!

The complete contents of the LLRPK-BLDR lower receiver parts kit are:

• Buffer Retainer & Buffer Retainer Spring
• Safety selector lever + detent
• Selector/Ejector spring
• Bolt Catch + spring, plunger & roll pin

All of these Luth-AR LLRPK-BLDR Builder Kit parts are standard AR-15 parts designed to fit a "mil-spec" lower receiver. Almost all currently available lowers are dimensioned to accept these parts, so compatibility should not be a problem. If you’ve assembled an AR-15 before, you should have no trouble installing these components.
