FYI…. Not sure how common knowledge this is, but there is an airgun vendor called Penchetta that sells a bunch of different Airguns, and high end writing pens, shaving kits as well. They are based out of Scottsdale AZ, and have Weihrauch LDC’s for sale!!! Worth a look if you need a moderator in .177 or .22 and wished you had the same choice and options that the Europeans do. I have one on the way. They are out of stock of another moderator called the decimeter, and not sure how quiet those are.
Because there are various interpretations of the law depending on who or where you live in the states. Moderators for firearms are heavily controlled through the NFA national firearms act. They have strict regulations and a very painful process to get them even i states ithat are legal to own them. The airgun moderator is exempt from this as it is NOT a firearm according the ATF and Feds. Airgun moderators are not meant to use on firearms and also would quickly break or be destroyed if used on a firearm due to the massive increase in pressure that powder burners operate in. For whatever reason, the moderator law interpretation varies from person to person. As I understand it, Airgun’s are legal to use with airgun designed moderators. Some companies get around this grey area by making moderators non-removal so they become integral to the barrel and thus can be sold. The Whole moderator issue in the states just does not add up either. You can legally and easily acquire many guns if you are of age, and not a felon. Yet a silencer has massive bureaucracy and a steep payment to process your application and paperwork. Yet in the U.K. Where they have strict regulations on gun ownership, background checks, the guns often come with mandatory silencers so as to minimize ear damage and limit the noise they make for people that live near where they are discharged.
