I just got back 2 electronic form ones I sent off about a month ago to make 2 silencers. Buying a silencer and putting it on a form 4 takes around 330 days, so by the time you buy it, the dealer to dealer transfer goes through and you send off all your form 4 stuff it will likely be over a year from the time you buy it to the time it's living at your house. I have 3 pretty nice center fire pistol silencers in NFA gulag. If I'm lucky I will have them before 2021. Hell I have a specter2 (which is a rimfire silencer) I have been waiting on the dealer transfer paperwork for 2 or 3 months. Some how there was an F up and the wrong specter2 got sent to my dealer. I say form 1 any simple silencers you want. Such as for 22LR, blackout, carbines, AR15 silencers and buy the higher end stuff like maximum style with recoil boosters such as the silencerCo ospreys, gemtech SFN for something weird like the FN 5.7x28 pistol, stuff with moving parts for delay blow back pistols. And form 1 for all the easy stuff. I had 3 designs to chose from. The easiest one to do is the big ugly mono core design. It's retard proof. All you have to do is drill out the end cap. Maybe not as retard proof as an oil filter silencer but those are definitely crap. Mono cores are known for being light and having loud first round pop unless they're huge. The second design is the inverted cone it's cheap light and effective. The third design is the traditional k baffel they are heavier and tough. I went with a dirt cheap probably made in china cone solvent trap for 22rim fire and a much nicer high end $300 k baffel solvent trap for gas operated and blow back 9mm guns. It's going to be my 9mm carbine silencer. Still need to drill it out. The cheap one actually works really well. The threads on the end cap are a little loose so I punched out the baffels a little bigger than I wanted to but it still works really well. It's definitely quieter than my 5 inch mono core gemtech. But this cheap one is about an inch longer and weighs twice as much as the gemtech. So you can get a very effective silencer for a 22lr for under $50. I used to keep my gemtech screwed on the end of my Ruger mk4 pistol under the seat of my car, now the gemtech is in the gun safe on a 22 rifle and my cheap silencer is stuffed under the seat of my car. Now you have no excuse not to have one, unless you are a prohibited person or live in some god forsaken shit hole where they're banned. I will update when I figure out how to drill out the k baffel one. I need to barrow a lathe.
