Ok, so I have some ideas about fabing up my own silencers/suppressers but I know very little about how the laws work when trying to do so. I know the Gov will want a ton of info and tax stamp stuff but do I have to have all that in place before I even get my ideas off the paper? Can I even build one and experiment/test my ideas? I have always been interested in doing this. Even as a kid when I learned about the Welrod pistol. Where do I find info on different types of supressers,ballistic ratios and most importantly....get started without making Uncle Sam upset? Thanks for the help.
