Here's the link: https://www.indianagunowners.com/forums/class_iii_nfa/54970-my_form_1_30_cal_suppressor.htmlAs stated above, the F1 has to be appoved before manufacturing any suppressor parts. CountryBoy19 F1'd a .308 can a while back, he may be able to give you some info on designs.
BTW, I'm really surprised those pics are still up. I haven't had comcast net for over a year now, but they must have left my storage up even after I canceled my service.
Yeah, I'm sure that's the real reason... they just love and respect their customers so much that they leave your public storage up forever.
It's because Comcast is so awesome.
And this site has a lot of useful information for building suppressors and it's free to register.
