This is a concept idea for based on my 45mm https://www.thingiverse.com/thing:2621139 VSR 10 Silencer.
If you have an airsoft rifle with M16 flash hider, the one with the round grooves to the back, and the thing does not want to screw off, or if you just dont want to go trough the effort of screwing it off, this should then work for you.
Basically you side the printed part over the flash hider and (and this is the part i am still working on) then you click it into place. At this stage there are holes open on each side, that takes an m3 bolt, or piece of copper wire. The ending idea would be to be able to pull the m3 bolts out so that it releases form the flash hider. The m3 bolts gets screwed into the pull piece, with relative free movement in the actual suppressor back end.
Please note, this is for the usage of a PVC pipe as suppressor, to save on printing material.
I added two photos of the silencer i have in mind of replicating
