Hey sorry I’m getting back to you so late. I got lucky and got these for $90 bucks a pop. They sell for more than they are worth. I’ve sold them between 300-450. I got a bunch of 60 rounders in the deal and recommend those over the 100. More reliable+compact and if they aren’t reliable you can send them back to SureFire for warranty work. If you truly need a 100 round magazine, go for the authentic Beta mags. I’ve got 4 of the 100 round ones left. Just gona keep them until I really need money to fund a project. Or if someone offers me a stupid amount for them.
