Will you show me yours if I show you mine?

Yes, it can be legal to make a silencer. For everything Form-1, from silencer designs that are easily made, to filing forms with the BATF, to 3D modeling. Remember, you must have an approved BATF Form-1 to make a silencer. All NFA laws apply.

The 300 blk is a hard one to do. If you hadn't said this was your first F1, I doubt I would've believed that. You did good on it.

My first form 1 can from 1998. Perforated tube can with expanded aluminum screen packing. Stupid quiet but the packing didnt last long between changes. I still have the gun with an entire different moocore form 1 can on it. My 20th century machine work wasnt half bad.

I'm still building mine cuz I just got my stamp yesterday. It's a QD can, but the mount isn't drawn. Don't judge my art skills 😆

YugoRPK,

Thank you for the great shots of your work,
especially the monocore picture.

Your statement " ...My 20th century machine work wasnt half bad."
made me chuckle thinking "Half-bad!! I should be so 'bad'".

Have you posted a YouTube of piece being shot?


Best.

Thanks but I'm not entirely sure youtube existed in 1998. In any case thats not a can I was truly proud of. Basically a 1943 design. The "new" integral is louder but it lasts more than 100 shots. Those old school perforated tube with a bunch of screen were pretty damn quiet with no FRP but they really werent the most accurate of pistols.

Thanks man, I was surprised to be honest.

The first round pop is a little on the rough side, I'm assuming its the short barrel, my blast cup is almost sitting on the compensator so who knows :roll:

Oh whatever man that's gorgeous, wish I had access to a machine shop and some training, maybe one day.

Interesting the screen packing suppresses soo well, wonder what the science is behind that.

I dont know theres a lot of science behind a screen packed suppressor. Just a perforated tube wrapped with screen. as the bullet goes down the tube the gasses get pushed out into the screen and cool and are trapped by the screen. The screen burnes up fairly quickly and it is a maintenance item to change. The Old HDM Bell lab silencers used screen washers ahead of the tube but good luck finding screen washers these days. Packed tube silencers work. For their original intended use they work fine. 10 foot or less capping a sentry or government official in the cranium and MAYBE 50 shots fired in its lifetime. . Practice being done with regular pistols .

An original HDM OSS silencer cutaway. Basically the same setup that Ruger had but the tube extends to the end. Crude yet crude.

I would call that a variant of the HDMS. I saw one/had one still in its original waxed paper box w/a spare packing re-core kit.It was un-used NOS. I had to destroy it as it was unregistered contraband. The shorter barrel was perforated to the very end plus it used a rolled bronze screen over the barrel section & bronze flat washers past the muzzle to the end of the suppressor.I would need my notes but believe the suppression tube to be only 6.00" long. The gun was also a green parkerized finish. This bronze screen did not burn up like the steel wool used it that picture.It was replaced only when it became choked by carbon reducing suppression.
Yes I almost cried cutting up a piece of history,thankfully BATFE only required the tube to be destroyed.
The only reason after 243 years the government now wants to disarm you is they intend to do something you would shoot them for!
