We have a manufacturing backlog, which means that orders going out the door today were submitted in the past. Orders submitted today are expected to ship roughly a year from now, using a conservative estimate of production rates. We ship suppressors to dealers every day. Most of those are not "pre sold" so the problem becomes matching up a customer who is looking for model X with a dealer who just received, or is about to receive, model X.
There is a drop-down about halfway down where you can select the model you need and it will report dealers who have just received or will soon receive that model. Alternatively, you can give us a call or send us an email and we can find a dealer who is likely to have what you need.
