This forum is privately owned. In that light, the owner can create any rule he wishes. Currently the forum rule on prohibiting moderator construction is out of order. This is now especially true with the Alphabet org silencer rule changes. If you have followed the debate between moderator3 and nobody1 and his leaving the forum over it, you will understand this unfortunate situation. The use of moderators has never been illegal on air guns. As the use of air guns is mostly in urban environments, moderators play a very important part of their use. Add to that the current popularity of the GK1 pistol, their use is almost mandatory. I have been designing and building moderators for many years. The construction methodology and materials used along with their effectiveness is very much in the interest of every air gunner. Nobody1 has been an important contributor to this forum and as a moderator constructor and an air gunner of many years, I agree very much to his position. The owner is doing a great disservice to the air gunning public and the air gun industry by his moderator position. I urge the forum owner to eliminate his restriction on this subject. Ultimately, as a forum member, all we can do is vote with our feet. Your call!
