View Full Version : oversized suppressors

November 4, 2008, 12:16 PM
I asked a question about 22 caliber suppressors and several of the knowledgeable members indicated it was better to get a 30 cal and it would work fine for a 22. I would like to get a broader sample of opinions. Please chime in if you have any experience.

Hm, no it won't work quite as well, but... if you can buy only one, for heaven's sake go with a 30 cal silencer. :)

That being the case, neither of the poll options really apply - asking if it will work as well is misleading - it'll be within a few dB, though.

I know the SEI/FEI DC .30 caliber can will work quite well on a .22 / .223 as long as you have the correct DC Vortex installed.

OP - sorry I can't help, as I'm learning about suppressors as well. I am interested to know if this idea holds true throughout all calibers. (ie, could you use a 45 suppressor for a 40? What about 9mm? A 223 suppressor for 22LR? etc)

Again, they WILL reduce the noise but not work as well. The poll choices aren't the best...

A 223 suppressor for 22LR

Those rounds are the same size (.22), so you would not give up anything using one for the other.

The others, I dunno. Never tried it.

Of course an oversized bore reduces the sound reduction of a silecer, but then the length and added volume of the 308 silencer compensates for that.

Some people use the .223 TAC-16 as an oversized 22 rimfire suppressor. It works, but is very heavy as a 22 RF can.

You want to be able to take it apart for cleaning because the lead buildup would hurt performance and make firing a .223 unsafe because of the risk of lead breaking off and hitting the bullet as it pases through the suppressor, sending it who knows where.

I have 22lr, 45ACP, 308 suppressors.

Your choise of suppressors very dependent on how you will be using it. For the most part the best suppressor for a caliber is the one it was designed for.

But for the sake of argument, lets say you can only get a 308 and you want to use it for 22lr. (Or you have a 308 suppressor mounted on a 5.56x45 AR-15 and want to use a 22lr kit on it.)

The first thing you will notice, is that the gun is barrel heavy. It does effect ballance. It does effect where the bullet hits down range.

The secand thing you will notice is that the 308 has more of a first round pop than a 22lr. This is really no big deal, but should be mentioned.

I didn't find the overall DB difference to be that significant. I think the 308 was louder than the 22lr but to be honest it didn't matter. I now use my 308 on my AR, because it is easier to Quick detach than to switch to the 22lr suppressor.

The third item is that you shouldn't shoot lead in a silencer you can't clean. When you shoot the 22lr it produces a little lead vapor. Over time this will coat the inside of your 308 suppressor. I don't shoot that many 22lr rounds out of my gun. At some point in the future, I will spend the money to clean the suppressor.

I reccomend if you can, buy suppressors specifically for each caliber.

If you can't go with a 9mm suppressor that you can take apart. It will be larger. It will probably be a little louder than the best 22lr suppressors.

Works pretty good -- can be used as a club in an emergency.

The cans for center fire rifle calibers are generally welded and shooting a bunch of .22lr would fill them with crap. The “buy big and use on anything” idea would also be a bad idea if you bought a can for 45acp the wound up shooting 300mag through it. The first scenario would just degrade the performance of the can the second could cost a lot more.

I might shoot:
.308 win
7.62 nagant

I don't believe I would run into any problems with a suppressor designed for .308, maybe that isn't true though.
