Came across this company quietbore dot com recently, seems to me to have their act together and some decent reviews on the suppressors built from their solvent traps (Form 1, legally.)
I'm pretty capable with tools but am not a machinist and don't have a full machine shop at my disposal. The Form 1 route seems straightforward, and Quiet Bore's company appears to be aware of how to make it easy to build your own (legal, Form 1) suppressor with their drill fixtures, parts kits, etc. I get the sense from their website that the experience would be a good one.
Anyone here have experience with Quiet Bore they would be willing to share? Or, how about other Form 1-solvent trap-to-suppressor companies that they'd recommend?
