from rec.guns… What spare parts ought the shooter keep on hand for basic operator maintenance of his AR-15 rifle?

New bolt complete, hammer, trigger, disconnector, disconnector spring, firing pin, firing pin retainer, ejection port cover spring and pin “C” clip, rear sight aperture leaf spring, 3 rear sight ball bearings, 3 rear sight ball bearing springs, rear sight elevation indexing drum set screw, safety selector detent & spring, rear take down pin detent & spring.

Hope this helps!

Thanks again for the kind interest!
