New Frontier Armory C9 Glock mag 80% lower and New Frontier jig. I'll post up links to them if you want the details. Both items new, bought for a project and ended up going a different route with it. Price is $150 in the Peru/Kokomo area. As this is not a firearm I will do PayPal FF or regular PayPal plus 4% to cover the fees and $5 to cover shipping.
