    I have been reading a lot about suppressors lately. I'm wanting to buy a Multi-caliber rifle can. Something for 5.56, 300BLK, 6.8, 6.5 Grendel and/or .308.

    I've been reading a lot about AAC 7.62 SDN-6. Seen a lot of people having issues with the 51-T mounting system.

    Anyways. Any suppressors that you'd recommend?

    Just recently had a NFA trust drawn up, now I need to add something to it.

    You can use the largest caliber rated suppressor for the smaller calibers, it just won't be as effective. The smaller the bullet, the more sonic energy will escape around it. You will also need adapters for different thread pitch.

    I get that part. I was looking for recommendations on makes and models of suppressors. I just want something that is Multi-caliber.

    Sorry Squawk, I don't know if such thing exists. Perhaps someone else does.

    Basically it's a .308 caliber suppressor that works with all the other caliber mentioned. Doesn't suppress other calibers (5.56) as well as a dedicated suppressor but will decrease decibel level noticeably.

    That certainly is possible. A 7.62 suppressor will work to its full potential on a bolt action rifle. It will make the rifle muzzle heavy, so you will likely be shooting from a bench or prone. I deal mostly with handguns and carbines, so it isn't very useful to me. As far as the brands, I am happy with the AAC 5.56 and the Gemtech II.

    The SDN-6 would work well with all the calibers you listed. There's nothing wrong with the 51-T mounts, I have 2 for my M4-2000 & 1 on my 300 BLK SBR. AAC has gone with a 92 tooth, taper mount for their new equivalent, the SR-7, which is suppossed to wobble less. There's also a mod for the 51-T mount to make it lock-up tighter if it bothers you. I'm not sure when the new stuff will actually exist, but it should help drive the cost of the SDN-6 down.

    Hearing 220 gr. 300 BLK subsonics thru the SDN-6 smack something down range will bring a smile to your face.

    It will be more effective on the smaller calibers than cans designed for them. The bigger 30cal has more volume which means better sound damping as there is more room to displace hot gasses and slow them down.

    My pref is for surefire cans they are pricey but damn quiet. I've got a qd surefire 762 and it returns to zero with only a little repeatable poi shift. This means you don't have to rezero each time just dial in your shift from non-suppressed.

    I've used the aac cans and seen them used and I went surefire after experiencing them. The issue I have with aac qd cans is the adapters aren't the best for running unsuppressed and they have an annoying twang. They also don't always return to zero meaning poi shift isn't always the same.

    If your doing a qd can I highly recommend saving the sheckles and going surefire.

    I don't have such information. It is true, however, that the size of a can partially compensates for the sound escape through its larger bore.

    The net difference is reported to be a few dB for the caliber-correct suppressor. It is unlikely a big deal if hearing protection is used. I have not fired a 223 through a 308 can, and cannot confirm or deny it.

    I have and do it a lot. Caliber correct 223 are muuuuuch louder than a 223 through a 308 suppressor. Its very noticable. The bullet is going slower than the gas. if the volume was the same the 223 can would be a minute bit quieter everything else can-wise being equal. You would need special equipment to detect it. The hole size diff tween 24 and 32 isn't much

    Semi auto gas operated rifles aren't terribly quiet to begin with when suppressed. I was very surprised in how loud my scar17 is compared to my wife's bolt action in 308 using the exact same can and ammo.

    It just boils down to volume and baffle design. The more the gas is slowed and allowed to expand slowly the quieter it gets.

    On a semi-auto like AR, other variables exist. The AR is a crappy host, in my opinion. A bolt action rifle would show the true grade of suppression. But for practical purposes, noted, thank you.

    I have a YHM waiting for a stamp. I like their QD and light weight option but they don't perform as well as others.

    The Specwar and likely the new Saker 308 perform very well and have great QD options as well as stellar customer service.

    308 cans work very well on smaller calibers. The higher volumes help a lot.

    I've never seen the appeal of the Surefire cans. They are twice the price of most quality cans and are no better. Just look at independent metering tests.

    i didnt buy it because of its sound abilities but repeatable return to zero and predictable poi shift on continous mount dismount cycles. long as a can has baffles and internal volume the ammount of suppression is going to be good enough for what i want.

    mine is also the more durable version which is machine gun rated for sustained fire. nother reason i went with what i did.

    surefire muzzle devices are also better than any other out there which is a huge plus for running unsupressed.

    if i was buying a can to leave on one gun and didnt mind rezeroing each time i removed it i would have gone with a cheaper model.

    chose it for a lot of reasons none of which had anything to do with suppression noise reduction levels. just depends on what you perceive as important to you which is why forums are so fun. you get lots of opinions on things you might not have thought of.

    when i bought mine the saker wasnt known about. i dont know of any repeatable poi shift testing with the saker 308 atm.

    indeed it is. ak47 are even worse for suppression. saw a guy violently dissasemble a can once with a ak47. very loud shots then the last one was REALLLLLLLY loud with shrapnel. heh. ak barrels, the bores are usually are not concentric to the line of the barrel so making concentric threads doesnt really help much.

    the scar isnt bad. its loud but its hearing safe. i was really surprised at just how loud a ar15 is when supressed. im not sure they are hearing safe when under cover.

    Well I obviously have some reading/research to do. I just want to get one before the King tries to make them illegal again. That or SBR. Or a precision build. I can't for the life of me decide WTF to do next. Something is gonna get added to the collection. What that will be only time will tell.

    Yes you do.

    Picking a suppressor isn't something to take likely since they have zero resale value. Get what works for your expected need.

    The reason they don't resale isn't because its illegal but the folks willing to pay the tax and wait plus transfer fees if your selling cross state lines through a ffl will want a new one vs a used with an unknown ammount of wear.

    I went with the YHM 762 titanium QD. I went with it because it had a mount for my M1a.

    I use it on my AR and my SCAR 16s. It is 15 oz and that is one main reason I got it. I have not noticed any point of shift on those. My M1a scope mount would not stop moving on me so I had to get a new one. Have not zeroed it back to test point of shift.

    So far I have been happy with it.

    Decided to build a Mk12 instead. Douglas Barrel is on the way. Saving now for a AEM 5 Suppressor. Apparently the same company that Manufactured the Ops Inc model 12
