22LR Silencer on Air Rifle?

berettaprofessor · Jan 15, 2021

This may seem like a strange question, but I have an adapter that allows a standard thread 22lr silencer (kind of like THIS) to be used on an unthreaded Ruger 10/22 barrel (fits around the sights). I believe the adapter would also fit my Umarex Ruger 10/22 .177pellet rifle. Does anyone know if it's safe to place the adapter and a 22lr silencer on the air rifle and fire it? I'm worried that the pellet might not be as stable as a 22lr passing through the silencer and that it might hit the baffles.

Do you have a check rod to make sure it won't strike the inside of the can? If it was aligned I think it will be fine.

Why not get one with a built-in suppressor? Non removable.

I think that's not a very good adapter for the purpose of maintaining a suppressor's Z axis concentric to your bore. I suspect that adapter is better for short components such as a flash hider or compensator.
If that was me I would get the air rifle threaded and change to a red dot or scope.

For some background: even an adapter which converts threads from one dimension to another has to be very well made and snugged up correctly in order to maintain the right fit. I can't see the adapter pictured being able to do it, and even if it can, I can't see it staying put with such a small contact area with those grub screws.

Don't want the paperwork or cost. Besides, I have a perfectly good suppressor...if it'll work.

It works just fine on a 10/22 22LR. I also have one made for a Henry AR7 and a S&W MP 15-22. Helps to spread that 22LR suppressor around. I'm just worried that the pellets will tumble as they exit the barrel and enter the suppressor.

And it stays put just fine.

Not sure of you're state bug here in GA can buy them with built in suppressors no paper work. Just want to get one that isnt removable. Feds could claim you intend to out it on a 22lr or something similar.

Right. If you get an airgun that is integrally suppressed (suppressor is built into the airgun and can't be removed without destroying it) then it shouldn't be a legal issue. If it can't be removed from an airgun then it doesn't fit the legal definition of a suppressor.

Does no one get that I have an air gun right now that I’d like to use? A Umarex 10/22 lookalike? The question is a yes or no..will a 22lr suppressor and adaptor work or not? If no one knows, then I’ll accept that. But let’s not suggest buying other guns altogether, please?

Please, do not use a powder burner can, on an airgun. Get an airgun specific can. US vs Michael Crooker is the controlling case as to airgun suppressors.

TL;DR A suppressor made for an airgun, threaded such that it will not fit a powder burner, is not a NFA item.

I was responding specifically to your comment that you didn't want to mess with "the paperwork and cost" of getting an integrally suppressed airgun--agreeing that there is no "paperwork" associated with buying an integrally silenced airgun. I should have quoted what I was responding to so it was clear.

The question is a yes or no..will a 22lr suppressor and adaptor work or not?

What is the muzzle made of? I can't find good enough photos to be able to tell. It's not uncommon for airguns to have a steel barrel with a plastic sleeve and maybe a steel sleeve over that for cosmetics. If that's how the Umarex is set up, how well the adapter works on guns with solid steel barrels probably won't have much bearing on how well it works on the Umarex in terms of stability/maintaining concentricity.

That said, I would think a baffle strike from a CO2 powered pellet wouldn't be a horribly destructive event. Just a pain.

I'm just worried that the pellets will tumble as they exit the barrel and enter the suppressor.

Pellets from a rifled barrel will act just like bullets. They won't tumble unless they aren't stabilized properly for some reason and you would know if that is happening by the horrendous accuracy and weird shaped holes on the targets.

If you're asking if the adapter/silencer would cause the pellets to tumble, the answer is no--not unless it were to somehow deform the rifling at the muzzle. If you're worried about that, put the adapter on without the suppressor and shoot it to see the results on paper. If it's working ok, and if the adapter is concentric to the bore and is staying in place, you're probably ok.

I get it.
You already have the suppressor, so you have the NFA/stamp side of it covered already. It is a technical question, not a legal one.
What suppressor is it?

Tactical Innovations TAC65. And thank you everyone, I wasn't aware that an internal suppressor on an air gun wasn't an NFA item. Something else to buy if the current drought in ammo continues....although in my area, pellets are just as scarce. I was in a Cabelas and two Academy Sports yesterday. Not a single pistol or rifle cartridge or pellet in any of them. Of any caliber...including the weird ones. Wait, I take that back; one Academy had three boxes of 450 Bushmaster subsonic...which I don't buy because it doesn't cycle my 450 AR.

Good point. I'll check.

If you're worried about that, put the adapter on without the suppressor and shoot it to see the results on paper. If it's working ok, and if the adapter is concentric to the bore and is staying in place, you're probably ok.

Great recommendation. Will do. And I'll report back.
