I have ordered from GunExpert not Arsenal CZ. It isn't as easy as ordering from someone in the US, mainly because of the language barrier. First, I installed Google toolbar, or some other translation service, and it will immediately translate the page when you open foreign language sites. I found what I wanted on their site, and wrote down the costs in the Czech currency. Then just plug the numbers in to find what the exchange rate is. I also saved the images of what I wanted so I could attach it in an email. I just sent the email keeping questions simple and to a minimal. Just be sure they still ship to the US, how much shipping will be, and if it is in stock. They respond quickly, but their English is broken. I paid via Paypal. They sent me a tracking number, and it was shipped out immediately. Reached the US rather quickly, but was hung up in customs for several weeks. Seems like it to about 5 weeks to get here if I remember right. I plan on ordering the railed dust cover mount from them here before to long.
