Suppressors 7.62 can for 300BLK and 5.56

[hydro556]

I am starting the process on my first SBR. Likely a 10.5" 5.56

Leaning toward AAC, but wanting to hear thoughts on the following scenario, and possibly any new cans on the horizon.

I want to try to get one can in 7.62 for a 10.5" 5.56 upper, a 16" RECCE upper also 5.56 and ultimately a 300BLK.

I would rather make do with one suppressor for the obvious reasons, but if there is not a 7.62 can that can make 5.56 pretty quiet, I will just have to take more time and get one in each caliber.

Can anyone point me to hard numbers and comparisons of folks testing out exactly what I need to know? I know somewhere on the web the info is there, but my weak search skills havent led me to exactly what I want to read. Thanks.

Call Mile High and talk to them about the new Ti "Reaper" from SAS. I am waiting for my form 4 to clear on one and can't wait. I have shot it on a 300BLK as well as several other platforms and it is stupid quiet for a 7" can. VERY minimal POI if any and repeatable. I intend to use it as a hunting can from 300WM on down to my AR's (556 and 6.8).

In my modest experience, the 30 cal cans work great on 5.56 stuff. I run my .308 phantom on everything, and I love how it works on my two .223's.

That is what I was hoping to hear. Thinking hard about the AAC 762 can, but a trusted buddy is pushing me toward the Surefire 762. Price is absurd, but I do intend to only buy one can for mulitple uses, so I dont know.

The AAC seems a good compromise.

Im running a AAC Clyclone on a 300 blackout and my 556. Havn't had time to test in on my grendel yet, but Hope to soon. It is very quiet on the blackout!

I also have the YHM Phantom in Ti so it is light and works great. It can handle my 300wm down to my 5.56. I have the QD hiders on all my barrels so I can change it out at random. YHM also does not void your warranty if you shoot sub-calibers out of their suppressor. I also use my Gemtech multimount for my 9mm, 22lr, and 300blk. Both make the 300 blackout very quite.

AAC 762-SDN-6

This is one I am leaning toward currently, and there may be one in my dealers safe soon, so I could get the paperwork rolling at least.

Maybe have it by Christmas, LOL.

Kind of infuriating what the gov makes us do to simply have a less obnoxious tool for the range.

Re: 7.62 can for 300BLK and 5.56

I havent heard all the suppressors, but I can tell you that both the Surefire and AAC 7.62 cans are very loud when used on a 5.56. Whe I say loud, I mean that you would still need hearing protection. I really like the AAC stuff, but when it comes to rifle cans there isnt really a "do all" can for different calibers shooting full power ammo. You will end up buying both. Buy a decent 7.62 can first and try it for yourself. Surefire is overated. We shot the 212 against the AAC m4-2000 on 10.5 inch SBR's and the AAC sounds much better hands down. The short surefire suppressors are worthless for a civilian shooter. All they do is hide the flash. I dont understan whey people are buying these.

The M4-2000 is an excellent 5.56 can and I can comfortably fire my 10.5 inch DI Rock River without earplugs using a brake.

If you only plan on shooting subsonic 300 blackout, any suppressor will be quiet including pistol suppressors. Ive been using a thread on AAC cyclone on .308 and 300 blackout and it does an excellent job of suppressing full power ammo, but is pretty big and heavy to be using on an AR platform.

Whatever you get, spring for the Ti, you wont regret it.

Re: 7.62 can for 300BLK and 5.56

I am really leaning toward the AAC for various reasons. I am trying to determine what a good price will be. I intend to buy it from my local dealer, because I use him for lots of transfers and have only bought like 2 pistols from him. Trying to support a good local guy. I am going to post some prices, which is where we started. Just to see if they are reasonable. Not looking for the smoking, nobody can touch internet type price.

Trying to help keep a brick and mortar going, while still getting fair prices for me. The following is what I would need(I think) to get the AAC 762 sdn can, and muzzle devices to get it running on my current RECCE and coming 10.5" SBR with QD attaching. I will add the muzzle device for the 300BLK if/when I get one. Please tell me if these are in line.

AAC 762-SDN-6 suppressor-$975
AAC 5.56MM 51T Muzzle Brake(for sbr)-$137
AAC 5.56MM Blackout™ 51T Flash Hider(for recce)-$83

Obviously, there will be no shipping, but there will be tax. Also, he expects to have an extra suppressor pretty soon, which would allow me to get the paperwork started much sooner. So that is a factor as well. Are these fair prices or should I work on them? Thanks.

Still considering others as well, this is just where I am starting. Not sure if AAC offers Ti, I will look.

317mill- Not doubting you, but "loud" may be a relative term. In my reading today you are the first review that said the 762 AAC can sucks on 556. Most reviews indicated it was a great multi cal can. You may be right but most opinions seemed positive using it on 556.

Re: 7.62 can for 300BLK and 5.56

Just another option to look at....
Gem Tech Quicksand. It is a qd, ti, 7.62 can that uses a quarter turn bilock system instead of the ratchet teeth like AAC.
I have one on order, should be in next week. I am going to be running it on my 308 bolt gun, a 11.5" 556 sbr and my 16" 556 patrol rifle. I also have plans for a future 300 blackout sbr, the Quicksand will cover the entire range.
Gem Tech states a 32dB reduction on 7.62 nato and they have told me to expect "about 29-30" dB on my 5.56 rifles.

Re: 7.62 can for 300BLK and 5.56

If you're starting fresh, why not skip 5.56 and just go with 300 BLK?
Supersonic is harder hitting and comes close to 6.8 SPC, and subsonic is just stupid fun suppressed.

I would recommend Griffin Armament's stainless steel RSTA for anything more than the light use that a titanium suppressor would be appropriate for.
There is a group buy thread here where you can learn more about it.
Cost is a very reasonable $855 which includes the transfer tax and mount.
It has a solid two point taper and thread mount system that won't back off like a conventional thread mount, and looks to not take that much more time to attach and detach than a QD mount.
The reflex design that extends back over the barrel 2.55" provides more internal volume, which results in greater suppression compared to a non reflex suppressor of similar baffling that has the same length past the muzzle.

Funny that that was your reply.

Over the past day or two that is exactly what I have decided to do. As opposed to getting a 10.5" 5.56 first and then the 300BLK, I am going to start with an 8 or 10" 300BLK. Still with the AAC can.

I am just looking at options for the upper. And the length. Complete Noveske upper vs having Kevin at HCS build me one, with a Noveske barrel.

The cartridge seems amazing. I had never paid it any attention until I decided to bite the bullet and do a form 1.

Re: 7.62 can for 300BLK and 5.56

Hydro...I'm in the same boat.

If heavy on AAC...you may want to consider the new SR7 model that uses the updated 90T ratchet mount. It has a bearing surface similar to the Ops Inc (and others) that ensures concentricity and minimal POI shift.

From reading AAC's blurb on the SR7...it seems they are targeting you as an audience. Anything 7.62 down works reliably. QD to boot.

I believe the MK13 is Ti. $$ though...and a bit bigger. But wow, just barely 14 oz!!!

Good luck, and keep us updated on what you decide

Re: 7.62 can for 300BLK and 5.56

My second choice to the GA RSTA would be the AAC SR7, and as Ishikawa writes, it's 90T and taper mount is superior to the 762-SDN-6's 51T non taper mount.
However, GA rates their RSTA at 30db suppression for 7.62 x 51, compared to AAC rating their SR7 at 25db.
Assuming the tests were comparable, the AAC is almost twice as loud as the GA.

Re: 7.62 can for 300BLK and 5.56

Don't waste your money on the AAC 51 tooth brakes, especially on a 5.56 or 300BLK, just get the 51 tooth flash hiders.

 

[317millhand]

Re: 7.62 can for 300BLK and 5.56

AAC also makes a really nice 300 blk upper. The SR7 and SR5 suppressors sound nice, but I;ve not been able to find one yet.

 

[hydro556]

Re: 7.62 can for 300BLK and 5.56

Will check into the SR7.

Dont want to get crazy on the costs, but want to get the most current suppressor. Especially if it is more effective for multi-caliber use.

Thanks for the heads up guys.

From what I've read...the SR7 is basically the SDN-6 with the updated attach system (and new external design).

For example...if you look at the site. They don't list the Cyclone-K anymore. They rebranded it as the "Hunter" model. Someone at Remington is paying attention to the market.

Re: 7.62 can for 300BLK and 5.56

I have a 762SD & 762SDN6 and I run both on 9" 300blk & 10" 223 & 18" 308 & 22" 308. On supersonic loads its almost the same hearing wise from 223 & 308 in my opinion. I've also run a buddies m4-2000 on my 10" 223 right after running my 762SDN6 and I noticed the SDN6 actually being quieter. I just thought it was due to the added volume.
One thing that I did to make sure I had positive engagement was I tried out several mounts prior to choosing to ensure they worked for my cans. I wanted to make sure they had no wiggle and would engage the last tooth possible. Some brakes locked up awesome but some didn't work to well for my cans but worked great for my buddies can

With that being said my next can is gonna be a dedicated precision can. I want to guy a 30BA

Re: 7.62 can for 300BLK and 5.56

Thanks guys.

I am pretty sure the 762 n-6 is the right move for me on this first one. Should be the one I can get in hand first to start paperwork.

Appreciate the advice.
