Im looking to put together a stash of spare parts for my ARs. What are the most common part failures? Those of you who frequent classes, what parts usually stop the show for the guy on the line next to you?
A spare bolt might not be a bad idea. I’ve never really seen a clean breakage of something.
More like cycling issues from an unstaked gas key and such.
Spare Bolt, extractor, gas rings, buffer spring, extractor insert, extractor spring, firing pin and charging handle.

Firing pin retaining pin. Most failed part for me.
Good list by Grant above, as usual.
Sure.

Excellent.
