Airgun moderator for .22 to .25.

The system has a treaded or non-treaded Tube and and EndCap. Internally the pellet will first enter the Blastchamber that diverts the pressured air into the next chamber that contains a large Screw. The screw enlongated the path of the escaping air. This results in a longer period of time the pressurized air is escaping the moderator, thus reducing the nois considerably.

Tested on Snowpeak PP750 .22 20J. Works perfect. No clipping and significant reduction of noise.

Tested on RTI Arms Priest 2 .25 80J. Same result. Works very well.

Added a version threaded for ½ UNF 20 (most common thread for airgun silencers) and a version for tapping any thread you need. Straight tapping the unthreaded version in ½ UNF 20 results in an even more accurate fit. Since I own a ½ UNF 20 tap I chase the printed threads to make it easier to install the silencer the first time. I also do not change the silencer to much; it is still only plastic. Maybe printing in a stronger material than PLA helps. But than again, if the threads get sloppy I just print another part.

I use some lubrication to gently screw on the EndCap to the Tube. There is some tolerance built in but it is dependable on filament, conditions and printer how that works out. I've made several of these silencers to give to friends and it is sometimes difficult to get the EndCap started in the beginning.
