Building Fat Rimfire can, need Baffle suggestions

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.

Building Fat Rimfire can, need Baffle suggestions

Post by plumber576 »

I purchased a 5" QuellTech titanium D-cell tube and endcap. It has Omega threads for the mount. It has a spacer built in.

https://www.quelltech.shop/online-store ... p194701144

My plan is to build a short and fat rimfire can, like a Turbo-K for .22lr. It'll end up on a .22 AR that I plan on SBR'ing. I have a Plan-B and ASR mounts sitting around so it'll end up with one of those.

This is my first Form 1 can and I have no idea what to do for baffles and could use some guidance. I'll need cups that fit a D-cell tube. I'm guessing I'll need a jig to drill holes and probably to clip the baffles. Any recommendations on these?

Any help or guidance would be appreciated.

Nobody? Is there a better place to ask?

I'm looking at radial cups. Can I run all Ti or should I have steel for the first cup?

I would close fill the can with baffles and use a very short blast chamber. 17-4Ph900 or other hard Stainless Steel is a blast baffle option.
Almost any baffle can do well in .22RF if enough are used and design good.

You can use Ti for the blast baffle but I would use 17-4 Ph900 or other hard SS. Rimfire suppressor blast baffles suffer more from erosion from the priming compound so a hard material will help.

Thanks. I'm thinking this confirms Stainless blast and the rest Ti.

On less than a FA .22 the Ti will probably be just fine.You really should find a machinist to help with this project.Precision of machining will gain you db's in this Short Non-Fat suppressor.
