I was wondering if you guys would help me come up with a parts replacement schedule by number of rounds fired for the AR15.
The standard for this should be with the goal of having an absolutly 100% reliable service weapon. In other words, for a plinker you might let the round count get higher for replacing certain parts, but for a service weapon or SHTF weapon, you might want to replace certain parts after a certain number of rounds fired in order to help prevent a breakage when your life or someone else's depends on the proper functioning of the rifle.
I am not going to offer any suggestions and let the people with a lot more knowledge then me weigh in on this.
A made up example would be:
1000 rounds: extractor
1500 rounds: gas rings
2000 rounds:
2500 rounds: charging handle
3000 rounds: bolt
5000 rounds: carrier key / carrier
etc.
BTW, those are totally made up figures, just to give an example.
