Home made suppressor anyone

[msorwan]

Just curious if anyone here has done a home made suppressor--LEGALLY OF COURSE--and what design you used, how does it work?

Been thinking about jumping thru the legal hoops and building my own. Been riflrsmithing for years and can't imagine it being that hard to make an effective suppressor.

i'll be sending in 3 form 1's this week.

I use Catia at work, so I've drawn up 3D models and sent pieces to a couple different machineshops to be CNC'ed off the models. Don't want all the parts in the same place just to be careful. I used K baffles and they were very quiet in .22LR. Haven't made a larger caliber yet. Forms are going very slow right now, even a Form 3 for my titanium .50 can has been atleast 6 weeks. I have a Form 4 pending since July. I would imagine a Form 1 could be even longer. I'd send it in and start designing now and collecting material while you wait. I made my baffles out of 303 because I had some, its stainless, and cuts OK. Tubes were seamless 304 and the end caps were 17-4. I've seen people ruin aluminum cans in .22 trying to disassemble and clean when they are all gummed up from AM-180 dumps so I made mine heavy duty and able to be soaked in tough solvents. The Whisper is much cleaner than .22 so you could mix some AL parts in to keep the weight down. Ti is the best, but you'll get bent on cost and having it machined. If you don't have access to machines it may be cheaper just to buy on a Form 4.

Could you maybe break down the cost involved in fab-ing up a .30 cal can in your choice of materials...? Provided a person had access to equipment of course.


BTW--- what about a manufacturing liscence? Need one to do it? Or not if for personal use and not for retail sale?

if you have an approved form 1 and then it's for you, not retail. no license with the stamp

[Mousehouse]

Just need an approved form 1 to build a suppressor as long as your state allows them.

I have built several. Like stated above check out silencertalk.com they have a lot of useful information on there. Do a lot of research before you decide on your design. Remember once you have built your suppressor it is done. You can't go back and change it if you don't like how it works.

I used k baffles in all of the ones I build. If you want a suppressor for your 300 whisper you can build it out of aluminum or stainless. I would build the blast baffle out of stainless and the rest of your baffles out of aluminum and use aluminum for the tube.

Another thought is to buy a 308 or 9mm suppressor for your 300 whisper. It all depends on how handy you are with tools and what you have access to.

At silencertalk.com look under the silencersmithing heading. They have some great designs with flow and great 3d drawings .. Paco's solidworks stuff is top notch ..

Good luck .. K

Just keep in mind that paco is a guy who is like 17 now and lives in komiefornia and probably has never seen a silencer in person. He does do nice cad work though!

The designs they have with flow are just pretty pictures as my FEA professor calls them. I don't think they quite match up what would actually happen.

I built one that is still the quietest that I have ever heard. We shot it against some high dollar,well known manufacturer names on sniper rifles and it beat them all.

Have a look...

I too have a pretty strong itch to build one of my own. I'm using the same nick over at silencertalk and hang mostly in the smithing section to get inspiration and education.

It would probably be cheaper for me to just buy one on a Form 4. But for some odd reason, I've already got a Form 1 or two filled out (but not so far as to take them to the CLEO for sign off).

I posted my first rendered design yesterday. I have no idea if it would work according to my theory and it would be a real PITA to build by traditional methods. It was easy to create the model in POV-Ray's Scene Description Language though :-)

The software producing the image is not CAD though. One would have to manually take the dimensions used in the POV file.

my 3 form 1's showed up today...WOOHOO!!!
