I ordered a G28 flash hider and several of the gen3 magazines from them last October. I knew the wait would be a few months so I let it sit until January. I sent an email and received the following response.
“sorry for delay. Usual the delivery time for in stock parts isn't that long. Cause of very long waiting time for the clearance for all customers outside Europe and also a lot of work here in our office. At the moment we work on several changes in our business and we get some delays here.“
I followed up a couple of weeks later and heard nothing until February 21 when they emailed me and said that because of changes in German law, they had to cancel the order for the magazines. I had seen that coming and was why I ordered in early October. I cancelled both orders and doubt I would order from them again (and they forgot to refund me too so I just disputed the charge).
