Airsoft Supressor (inner supressing structure) v2

I wanted a custom, short, flashider at first then i saw how easily i could design a short supressor instead to dampen the BBs sound a bit.And here we are. Currently its under development, and rigorous testing. Long range testing Sound and Spectrum analysis is ongoing together with airflow, sound and pressure simulation.Once there will be changes expect this Model to be updated accordingly. Until then all findings or advice is appretiated :) Current version printed in PLA, final version is expected to be printed out of ASA-GF or PCTG. v1 removed (might still be useful for HPA, let me know if you need it back)v2 added (changes: testing the v1 version i had some choking issues, first shot was fine however afterwards the piston couldnt be backfilled with air, and there was not enough to compress anymore leading to a redesign)
