I was looking for ideas, or designs others have made on how to mount a silencer without threading the barrel. This would be for a .22lr, so the pressures would be low. I have the ability to get the barrel threaded, just wanted to see what some other options would be. Thanks!

Muzzle adapter coupling is your best bet.

But seriously, threading the barrel will be loads better.

With muzzle couplings you're trusting that the barrel's surface is concentric with the bore, and that the coupler itself is also made to tight tolerances. Not worth risking the investment into a suppressor if you ask me. Even if you do a Form 1, that's still the $200 tax stamp and 3 months of inconvenience waiting for approval.

There are threadless mounts, such as the tri-lug mount on HK MP5's. However, you generally have to thread the barrel first and mount a tri-lug adapter, so that makes avoiding threading moot.

What .22 lr host are we talking about? There are many hosts available with factory threaded barrels (or have aftermarket replacement barrels). That may be the best, safest, cheapest way to go.

Hi,

I have all my rifles but one with muzzle couplings. From .17HMR till 7 mm.

They work just fine. You have to take into account the extra tolerance when building the suppressor. That’s all.

Of course, threading the barrel is a lot better: Be sure the threading is perfect otherwyse you also have extra tolerance and it’s forever.

Best,

Paul

I am amazed there is a guy building these, and the price seems very reasonable.

He's creating a custom collet clamp, and IMO that is the only alternate way to do it, but to be done properly, it requires some good machine work with tight tolerances, and the issue I see is that bores are not always concentric with the outer diameter. On my own Ruger MK2, I turned the muzzle threads and found that the bore was out of concentricity by a full 0.015". So all I can think is "Watch out for baffle strikes" with any sort of clamp-on device.

Thanks for the replies, its going on a remington 597, they do sell threaded barrels for it, but ill just use my friends lathe and thread the factory barrel, not worth having the end of my can blown off potentially :).

Any kind of clamp style is best done with the TWO POINT method. When there is no shoulder for alignment, you need two points of contact.
With muzzle threads, there are still two points but they are so close together, they`re refered to as one.

Surprised to see D.A.Q.'s listing, he has been around for a long time; if memory serves correctly I first ran across him in the SN (Shot Gun News )
when the internet was two Dixie cups coupled between a tightly pulled string. :)

I still have his list from long ago if it is still the crusty but quality machinist.

Take a look at some of the old Maxim stuff.

What I have seen involves an "adapter" that is hammered onto the muzzle of the firearm. This adapter is a tight press fit onto the OD of the barrel and it has a threaded nipple off the end that the suppressor goes onto. I think some of them used an interrupted thread.

I assume the maxim stuff had enough tolerance built into it to account for alignment problems.

I've used DAQ's adopters and other products for years and the quality is as good as anyone's.

No way I'd put a can on that thing! Just have the barrel threaded and have it done right.

No problem here with Quackenbush's adaptors. I have two that work fine.
