Ironically no AR parts but I also have parts for M1 Garand and M1A and have replaced extractors in both. Half the time I buy spare parts it's things I grab at a show for example. Then I forget where the hell I put them so I buy more. A week ago I was trying to organize the safe (I need another safe) and found a bag of AR parts I have no clue when or where I got it. Has me wondering what good are spare parts when I don't remember where I put them?Has anyone actually needed any of their spare parts?
