WARNING to all trying to order from cz-parts. CBP ( Customs and border protection) WILL seize the magazines due to them being imported gun parts. In order to release them, the CBP requires us to register them through the ATF using the form 6 part 1 on eforms. After 2 weeks my form got approved and i got my permit for my 2 22lr magazines. Unfortunately, there is a customs and import fee as well as a storage fee UPS charges when they hold your package. IT ADDED UP TO OVER $625 !!!
So, my recommendation is to suck it up and buy those $70 magazines. And wish me luck because im not paying $700 for a couple of 22lr magazines.
