Need some schooling on supressors


May 11, 2011, 02:56 PM
Ok, this is probably not possible but I wanted to run two questions by the group...

1) Can the same suppressor be used on a 7.62x39 AND 7.62x51? There is pressure difference but it does not look like a lot on paper... 52k vs 60k. In theory it should work but as we all know practice is typically very different.

2) This one is a little tricky... I have an M1A and an AK. Lets say that in theory I want to use the same suppressor on both. Is this possible? True to bore threading could get interesting but in theory should be possible. Does this even make any sense at all? I would LOVE to be able to have one suppressor that I can use on both of my rifles. Also what are my options for mounts?

As always, the advice and info is really appreciated!

Absolutely you can use one can for multiple firearms, especially if they are both rifles and thus operating at roughtly similar pressures.

You can even use a larger-bore suppressor on a smaller-bore gun (like a .30 cal can on a .22 cal rifle), with reasonably good results.

You will probably need an adaptor or two to switch between the different thread patterns. Contact almost any silencer manufacturer and ask how they'd recommend you handle it.

What you want is absolutely do-able. A lot of people do exactly that all the time. I use my 30 cal suppressor on a Remington 700P, an AK and also on a FN FS2000. I haven't gotten around to getting the mount for my M1A yet.

Look at Yankee Hill. They make suppressor mounts for both guns you listed. Look down the page at the 7.62 Phantom flash Hider/mount.

Plan your suppressor around you most powerful caliber, and you'll have a very effective one for the lesser caliber. I'd have your weapons all threaded the same - that's what I've done and it makes things easy. Just be aware that suppressors increase back pressure, and can really bang the bolt and op-rod on an M14 copy so check those parts. I eventually went to a grooved NM piston for my M1A.

I use my suppressor on my AKs, My 308 bolt gun, my AR15s and my .22s. Works fine with all. I also plan on using it on my Romainian PSL and M1A whenever I can get a thread adapter made. My local gunsmith will make nice stainless adapters in any thread configuration for about $85.

The 7.62 Phantom from YHM is rated to handle a 300 Win Mag down to your 22 centerfires or really anything you're comfortable with hanging a 2 pound suppressor off of. The smallest caliber I've used mine on is a model 700SPS in 223. I own the same rifle in a .308 and I've found the .223 with a 7.62 suppressor is every bit as quiet (if not quieter) as the 308. The performance on my Rock River LAR-8 wasn't quite as spectacular as I had hoped mostly due to the extra noise exiting the action. You may find the same with your semi-autos, but I haven't heard a suppressed M1A or AK. I'm sure your affinity for bolt-action rifles will go up once you hear the difference first hand. At 15 ounces, YHM's new titanium 30 cal unit would make a fine choice if the combination of versatility/lightness were your demands.

Below I have a Phantom on one of my 10/22s and a Walther P22 strictly to demonstrate the extreme versatility of a 30 cal suppressor. I haven't fired any rimfire cartridges through it yet although I'm sure it would do a fine job:D Over the 10/22 is a Model 700SPS in 308 and above that is the same rifle with an 18'' barrel chambered in 223.
