Suppressor shopping for my AR's. Opinions needed.

[DanWalker]

Looking for advice on a suppressor to be used on multiple hosts. Wanting to run it on AR's chambered in 7.62x39 and 45 acp. Also want to be able to use it on a .308 bolt action rifle. Any suggestions as to models I should be looking at?

[USAFrox]

Guess I'm showing my ignorance, but I thought suppressors were caliber specific. The hole for the bullet to go through has to be very close to the diameter of the bullet, or it won't block much of the sound and gases. Again, I have no experience with suppressors, but that was my impression.

Subsonic (?) is rep'ing them.

Don't have one, but thinking and these seem to break down for cleaning lube and lead from the suppressor it self....

Your not gonna find one can that works GREAT to cover all of those.

with the 7.62x39 and the 308 you can use the same can no problem and it will be efficient.
But with the 45 acp, that whole is a lot bigger then the 7.62 (lets say .310 vs .452). That .142 in difference doesn't sound like much but it does matter.
Also its going to be a big can in order to catch all the gases from the 308 vs the 45acp.

I don't mind if it is a big can. The 45 acp is a SBR AR upper from RMW extreme. I don't plan on using the can on a handgun. Just looking for one to use on these three rifles. Not sure if there is anyone who makes such a beast.

you will need to get 2 cans on for 308/7.62 and one for 45 you can shoot smaller calibers through suppressors with out much issue though you will loose a little efficiency like say using a 7.62 can on a 5.56 just about a 2 mm difference and and 556 is so loud anyway you wont notice much difference. in theory you could shoot 308 through the 45 can but you have a pretty big gap 3.84mm which will really start to eat away at your efficiency that and the 45 caliber can will be designed for 45 acp and will not hold up well to full pressure 308 loads. also 45 cans are pretty loud with 45 unless the are ran wet or are huge so the are less than ideal for your application. i would recommend a 308 can with quick detach capability (surefire, aac, yhm, thunder beast)so that you can easily move it from gun to gun and the QD adapter (usually a muzzle brake or flash hidder) will serve to protect your threads and crown as for the 45 cal ar your best bet would be a large sub gun suppressor or you could get a smaller pistol suppressor with the booster disabled so you could also use it on pistols with the booster in place though the sub gun can will be quieter and hold up better to rapid fire

Yankee hill machine is probably the most bang for your buck or rather the least bang in this case

Most pistol caliber supressors are not built to handle the pressures of rifle rounds. The only real option for a do-all would be a custom job most likely, it's gonna be BIG and HEAVY. You need 2 supressors to be effective with this range of calibers. If you want quiet, the 45auto is the way to go.

[Lonegun1894]

Having dealt with a lot of cans, and now owning a couple, with another two on order, I agree that you will need 2 cans. As has been said, most of the pistol caliber cans won't hold up to full power .308 for long, and due to the legal situation with these items, they can be a pain to service or have serviced. Now if you were planning on using subsonic (think pistol pressure) rifle rounds through your rifles only, then the pressure wouldn't be an issue and durability wouldn't either, but you would still lose some efficiency due to the caliber difference. Lets put it this way, the two cans I have coming are .223/5.56 and .308/7.62, due to the difference in efficiency--and I'm not rich or even anywhere close. I did however save up the cash to buy both due to my past experience and knowing that even slight differences on paper and company claims can make a huge difference in actual use. The ones I have coming are HTA cans due to them being one of the few that are made to be disassembled by you and me instead of having to be sent back, and the vast majority of my ammo is cast, so cleaning is important to me.

I know this isn't the cheap answer, and therefore not the answer you wanted, but I would buy the can for whichever gun you use more now first, and save up for the other and buy it second if buying both at once isn't an option. If costs more up front, but you will be happier with the results, and once you have both in hand and can try both the .30 and the .45 on the .30 cal guns, you will see exactly what everyone has been saying. We're not saying that the .45 can won't work on the .308, just that it won't work as well and it will basically wear the can out and that costs you more in the long run than just doing it right from the start. We're trying to save you a few hundred (or more) bucks.

Thanks!

Yep, I'd say you need one 45 caliber can for your 45 acp low pressure
and one high pressure can in .308 for 308 and 7.62x39 and smaller like 223.

Different pressures require different construction, using a high pressure round with a low pressure can is a problem in a BIG WAY. Remember that what you are buy a can for is sound reduction - I have heard people complain about the actual cost of the can when purchased but if it's a good quiet can they don't complain after using it and seeing it against a cheaper can that is noisier. Spend once and cry or cry whenever you use it.

Actually I'd look at the SWR Octane for your 45 caliber can. ! It's user cleanable

And if your shooting lead in your rifles I'd take a good look for one you can clean

SWR Specwar 7.62 - multicaliber test -
so you can see the difference using 308 can with different cartridges

I use my 308 AAC cyclone (not user serviceable so you have to soak it to clean it)
on 7.62x51 FAL, 7.62x54 Mosin Scout, .243 WCF Remmy bolt gun, AR15 .223
to do this with my thread on can you have adaptors made for smaller threads
like the AR's 1/2x28 to make it up to the 5/8x24 that the suppressor is threaded for.
If your buying a Quick Detach mount be aware what the mounts cost.

Lighter weight can made of titanium are available so look at the balance of the rifle with the can mounted, it makes a difference.

[Copper75]

+1 for two different cans.

I'm in the same boat as you. I bought an AAC 7.62 SDN and am saving up for .45. (Probably Osprey)

You can get rifle grade .45 caliber cans but it would cost about the same as the two others and you will not be as happy with it.

My 2 cents ...

I could build one that's not too big or heavy that would work efficiently with both calibers but importing such a beast from NZ would be a problem. Also, I'm not ready yet. It may not be the most efficient with 308 but would sure work well with 7.62 Russian and 44 mag. What's the demand over in the states? Maybe I should get a move on and get up and running.

[Lonegun1894]

As to demand, lets put it this way, I have two cans, and am waiting on stamps to pick up two more I bought recently. But I also have several friends who think I am NUTS for being willing to spend the money and do the paperwork and such to even get a single can, so who knows. I do know they are getting more popular here in Texas since they were recently legalized for hunting use, it that helps any. I have no idea about other States, or what would be involved in importing one from NZ.

Coastal Guns suppressors had good write ups in Small Arms Review magazine. Good quality, low decibels and reasonable cost.
