Well, it was the rule changes at AGN that motivated me to join HAM. Rather than looking for an opportunity to express unhappiness, I would like you to understand the extent of AGN's new policy. And, how my actions unintentionally "helped" precipitate those changes:
New AGN Policy: The reselling of any and all unmodified detachable commercial airgun moderators is banned on AGN, via their classified section. So, something that is sold, bought and used by airgunners in the belief that these products are legal is now considered illegal by AGN. Either AGN ownership knows of a law change, or are concerned about being held accountable for potentially illegal actions they did not commit. On top of this, all discussion about making or altering airgun moderators is now forbidden on AGN; including the sharing of images and of design files.
While the classified ban is telling, I am not connected to that. However, I am in part responsible for the attitude change towards moderators in general:
My Confession: I am guilty of designing custom airgun moderators and shroud inserts, and then showing the designs on AGN. My Avatar image here is of my
Shorty muffler design for the Huben pistol. Apparently showing a section image of the spiral baffle inside contributed to the AGN rule change. On top of that I shared the STL file for this moderator, and a number of other more conventional looking ones, that I gifted to the airgun community.
The argument is that showing people the inside of an airgun moderator is helping them to make one for PBs. If someone is going to make an illegal PB device, everyone already knows about hardware store pipe and washers. AGN's underlying argument is to avoid blurring the line between airguns and PBs. While that sounds reasonable, that ship seems to have sailed, ballistically speaking, with big bore airguns. Taken to its logical conclusion, this could end up promoting a sub 12 FPE / FAC type legal distinction. But that is not what this is about.
The last straw for AGN was a poll about airgun moderator mounting threads, where someone suggested adding common PB threads. Anyone who makes an "airgun" moderator with PB threads, or adds an adaptor displays intent to break the law. In my opinion, they should face prosecution, without that having any bearing on the intended use by the rest of us, of airgun moderators that sport airgun attachment thread patterns. As such, I would refuse to do a custom design for any 3D printable moderator having threads that suggest illegal intent.
If the argument is that someone could add an adaptor using common hardware store parts, the counter argument seems to be that they could make a complete device from hardware store pipe and washers. And, if they adapted an airgun moderator or made a complete one for a PB (without legal permission), such individuals would be breaking the law. Not Huggett, or DonnyFL; or a custom airgun shroud or moderator maker, or designer.
If the images below violate the rules on this forum, I will gladly take them down. I emailed the HAM forum owner a few days ago to ask about the rules governing the discussion of custom airgun shrouds and moderators. After not getting a reply, I decided to join the forum anyway. Now, the question appears to be, does the HAM forum serve to "chum the water" for the sales of commercial airgun products only? Or does it also encourage the development of new ideas by mere enthusiasts, starting with custom designs and general tinkering; potentially resulting in new and improved commercial products in the future?
As my sharing of designs on AGN started with a custom short offset moderator for the Huben GK1 pistol, that is what I am sharing below. The reason I posted it on AGN was because I was approached by an AGN member to design this muffler for him. As I did it for free, I felt that sharing it with more interested parties should be OK.
The request was for a less than 3 inch long offset muffler, that would not block the open sights. The general shape was to compliment that of the Huben pistol. It would also enable snag free holster use; hence the slanted front end. With such a small volume to work with, my goal was hearing safe. According to the original requester, the performance exceeds expectations. Due to the odd outer shape constraining the internal space and volume, I elected to use a spiral shaped blast chamber, to "trap" air and slow its exit. Unfortunately all the development and testing details on AGN are no longer visible.
Anyway, if the HAM forum would rather not see such designs, nor host discussions about how to make conventional looking airgun shrouds or moderators more effective, with improved grouping ability, then I won't post any more of them. On the other hand, if there is interest, without objection from HAM, I am willing to share more designs, so others may benefit from them.
Consider this my introductory post on HAM
