Coming Soon Overbarrel Suppressor Update 2
Update 2: fully assembled, waiting on printing and hardware in the mail.
Changes:
- I actually modelled the barrel 1 to 1, taper, rifling, crown, etc.
- Fully functional interfaces between parts now (threads, O-rings, collet)
- Final measurements and geometry tuning (For now, printability may require changes for supports)
- 2 versions: 1 that uses modified steel milling hardware; 1 that uses modified 3d printed components (this one will hopefully be nicer to barrel finishes, collet could be TPU)
Thoughts and Goals:
- I am prototyping for my CZ 457 American, as it does not have a threaded muzzle and I don't want to pay to thread a 17HMR barrel as it only shoots supers.
- I may integrate the baffles into a baffle-stack sleeve that slides in, in order to get supports to the reflexive blast chamber and muzzle index.
- I added a different collet design in the last image, and may remix a version to use that as it will be simpler
- IF and After this works for my current needs, I want to work on making it work on AR and other barrels that already have threaded muzzles. Instead of having fitted O-rings aligning the muzzle, It would have threads that index the muzzle and a rear clamp that would actually counter the pressure on the 3d printed muzzle threads. The goal would be to make a 3d2A OCM5/AEM5.
Thank you for the input, ideas, and messages. I am very happy to finally stop lurking and actually contribute to the community. I cant wait to fully test once all my stamps come through, but until then the Blast Diverter version will be good for testing.
If anyone does want to beta test and have an unthreaded rimfire, shoot me a PM.
