  1. Have to say hands down one of the best companies that deal with used ammo, single or linked. I’m a combat vet that loves to add to my bar in the basement and J&M Spec had everything I needed at a great price. Highly recommend. 1st Cav all the way!.

    1. Good morning. Thank you for the question, but due to international regulations I cannot ship outside the US without going through a US exporter and Swedish importer.
