F1 30cal can on a 22LR

[Joel45acp]

I'm currently working on a Dsize direct thread 30cal can using SS FP(.75" highwall) that'll be used primarily on a Remmy 300blkout bolt gun using subs and an occasional super. My question is will it also work adequately on a 22LR rifle with the proper stepdown adapter? The Can will have a SS tube (7.6") with either SS or steel end caps and approximately 7 clipped baffles for a total length of 8.25". Bore on the can will be 0.360". Thanks for your time.

Unlikely to be as quiet as a properly designed dedicated .22lr can, but it should make the smaller round hearing safe. Don't recommend doing this unless the thing can be dismantled, frequently, for cleaning. Using some white lithium on the first couple of baffles and cleaning every hundred to two hundred shots will go a long way in preventing nasty rimfire residue build-up.

Thanks for the insight. I’m just torn between building a 30cal to use on my Remmy as well as on a Ruger 10/22 or simply build a dedicated 22can and purchase a commercial 30cal can. Got an email confirmation from the Feds this morning so it shouldn’t be long now. Thanks again

Build both. The can you already have at 7.6" long, and assuming sized appropriately for .30 cal at 1.5"-1.625" OD, is too big for rimfire unless you get creative in ways not really possible without a lathe. An inside diameter of about .9" and 5.5"-6" long with 10-12 baffles is ideal for .22 LR.

Thanks for the info ECCO. I’ll stick with the 30cal can and see how it goes. If all goes well then I’ll start on a dedicated 22can. Thanks again.

I had to try it one time after I finished my 22 build. On the same rifle with the same ammo my 30 cal YHM Phantom (which is admittedly a beast compared to some of the options out there now) is about as quiet as my F1 built 22lr suppressor...at roughly 4x the weight and 1.5x the diameter and length. That is why I decided on a dedicated 22lr for my first F1 build...

Out of curiosity, does anyone commercially make a .22lr suppressor in ~0.9” ID, 5.5”-6” length, with 10-12 cones? Seems there are a few that match two of the three but I didn’t see anything that was all of the above made from a major manufacturer.

Well, yeah



The TBAC takedown 22 is roughly the same size as my model, has 11 baffles.

I wasn’t familiar with that can. Everything else I saw was mostly 7-9 baffles.

I don’t want to sound doubtful on your suggestion, I’m just trying to figure out why only one company does it this way and the rest do it a bit different. I know cost is a huge factor, especially on production scale so I could see less baffles make more profit.

I'm not the only one. Like I said, TBAC TD22 uses 11. Griffin Checkmate I believe has 13. Rugged Occulus has 10.

You can't compare K baffle cans to cone cans, though, so forget the count in Dead Air Mask and AAC Aviator.

In the end, of course, it's what works for each of us in the real world. I played with a number of baffle profiles and counts before I settled on what you see above. Lots of designs with lower baffle counts or even monocores work well on rifles but not so hot on handguns, which is what I found with my first generation Ocelot after I bought a meter. Suppressing a .22 rifle is just easy, and really doesn't tell you squat about the can's performance. If you want to validate a rimfire design, you stick it on a pistol with a 3 or 4" barrel. Some of the popular ones like SilencerCo Sparrow and Surefire Ryder that do fine on rifles are loud as $^#& on a handgun.
