Most critical AR15 spare parts?

[TreeHugger]

Want to order the most critical spare parts that can be stored in the grip of an AR15. Am I missing anything below?

* Bolt gas rings
* Ejector w/spring
* Ejector pin
* Extractor
* Extractor pin
* Extractor spring assembly
* Firing pin
* Firing pin retainer

Thanks

I keep an AK with mine

If I was really worried I would just keep an entire spare bolt / firing pin.


and ammo, always more ammo! !

I agree^^ Those you list are all important, however I keep an entire bolt assembly AND spare parts for extended outings. I like redundant systems
