Quick Tip: Must-Have Spare Parts for Your AR-15
We asked Brownells Gun Techs Steve and Caleb bring their unbeatable combination of wisdom and good looks to answer an important question: What spare parts should I keep on hand for my AR-15? Gas rings and buffer spring wear out through normal use, says Caleb. And he has a handy rule of thumb for telling when that buffer spring needs to be replaced. Most likely to fail on the bolt / carrier group are the extractor spring and pin. The cotter pin and cam pin can break, but more often they get lost when the BCG is disassembled for cleaning. Steve says he's tried but has never succeeded in getting an AR-15 firing pin to break.
