Many people are asking me “Which spare parts to get for my AR15?” So, let’s get to it.
Which parts on the AR15 are most common to have issues or breakages that will render your weapon useless? Here is a list of parts most likely to break that you should keep on hand. Extractor spring insert, Extractor spring, Cam pin, Trigger Spring, Firing pin, 2 Firing pin retaining pins, Safety detent, Extractor pin, Detent Spring, 3 Gas Rings, Disconnector, Hammer Spring. These should go wherever your rifle goes. You can buy field repair kits for about $30 at Palmetto State Armory.
These spare parts should make sure that you are not out of the fight for long if something minor should break. I also like to have a spare bolt on hand. Of course the very best spare is another complete rifle, however, although I own several AR-15‘s, I also have spare parts on hand as well. Just in case.
