M4carbiner's,
I need some serious purchasing assistance. I've decided to get a can and I'm totally lost... :confused: I own a DD M4V7 and I'm looking for the following features in priority order:
Maximum sounds suppression
Minimum loss of zero at 100 meters
Quick Detach
I'm leaning towards a Surefire or AAC model but I can be persuaded towards other brands.
Any comments or help here would be totally appreciated.
You can't really go wrong with either of those brands. They make great stuff. Personally I would go on Silencer talk and just start reading as much as you can.
Any reason why you want your first can to be for 5.56? I don't currently own a suppressor and am not in any way trying to tell you what you should and should not be buying, but I too was looking to buy a 5.56 can for my first NFA item. After doing some research and looking at the DB numbers, you see that 5.56 doesn't suppress well, at least compared to calibers like 9mm and .22 LR.
I fully intend to buy a suppressor for my AR at some point, especially once I SBR it, but my first can will be 9mm or .22 LR.
Agreed .22LR and 9mm cans give you a lot more Shhh for the buck. :)Quote:

A 5.56 AAC CAN will treat you well.
Noob here as well, but from what I have been looking into, I am considering the 7.62 can and using adapter on the 556 to work with it. That way it works for many more platforms and you only lose 1 decibel or so. Anyone please chime in if I am wrong on this.
I believe there is a decibel difference, but it was hard to hear the difference for me. I shot a sdn6 on my AR next to a m42k a couple weeks ago and I couldn't tell a difference.
Surefire has more options for total length of the suppressor. I think there are five or six options ranging from 4" short to like 10" long
AAC basically only has the mini and m4-2k.
But still, another vote for the m4-2k for the overall cost/performance of it.
that work well. You get a versatile-use can.Quote:

I was able to hear a distinct difference in silencers for the first time a few weeks back. We shot Pappabears AAC Mini 4 and M42000 side by side on ARs and Swapped them both out on a Rem 700 bolt gun.Quote:

I think he was referring to the difference in going with a 7.62 vs 556 can. If you own a 308 or something the ability to use the can on several guns be a big factor. They will be slightly louder but not by much. I also agree with picking up a 22lr can as your first. You will probably get a lot more use out of it.Quote:

I would also check out Silencero. They've got some great stuff as well!
Very informal test I was involved in proved to me I made a great decision by getting an AAC 7.62.
Versatility is awesome. The can shares time on an AR, 300blk, and a 308 bolt. It is truly awesome.
Suppression is about the same. A few decibels better for the 5.56 can but still leaves you with .22/5.56 options only.
So if money is kindling for you, get every caliber. For me it is an issue and best value is the 7.62(whatever flavor).
There is not a 556 can extant that will make it truly hearing safe. Tolerable, certainly, especially shooting in open snowy fields or some such. A 7.62 can is going to be very long and feel very heavy. A mini can will be as quiet for the shooter (but not many observers) as something bigger.

I gotta say, 5.56 is still really freaking loud suppressed. If you're looking for recreational use, the pistol calibers and 300BLK are much more fun.
My apologies, I worded that poorly. I was shooting the SDN-6 off my DDM4v1 next to a N4 ,with SB, and a M42k. I'm sure if we had something to measure it, it would have shown a difference in the decibels, but I couldn't audibly tell the difference, not scientific, but just my experience. It might be because I was behind my gun and lateral to the M42k, but others said they couldn't hear a difference either.
Here's the rifle.

Well this thread went off in a strange direction. Guess I need to get a 300BO upper instead of a suppressor?
I have a lot more research to do.
You don't have to get a 300 upper. Those were just some suggestions to consider a 7.62 can for use on 5.56, as it will give you that capability in the future without having to buy another can. For all intents and purposes, it would be just as effective at suppressing 5.56 as a 5.56 can, but with more versatility.Quote:

I would have brought a .30 caliber can that was QD and used that on my AR15's. The suppression is near identical to your ears and the versatility is way more. Instead I did as you are thinking and went with the AAC SPR M4 a QD maximum rated suppression silencer with 5 positions to minimize the zero change... Great suppressor, but costly.
Thanks for the feedback. So do i have to have any special mounts for a 762 can that I plan to place on a 556 barrel?
I would imagine so considering most of the .308 barrels are threaded differently.
With AAC cans you match the mount to the caliber. So a 51 tooth mount for a 5.56 gun will hold the 7.62 SND can for example.Quote:

Mine happens to be the 51t design and you have to make sure the AAC adapter it is going to attach to is either 223/5.56 or 30cal depending on what rifle it is going on.
For instance, you don't use a 223/5.56 qd brakeout on a 300 blackout rifle.
Read some and search around here. You will find most everything you are looking for.
ETA:mark. Beat me to it and was more concise.
Not for the AAC SDN6. The 51T mounts are available in the common diameters/pitches.Quote:

For me, the AAC m4-2000 was the best balance of sound vs weight/length. I intend to get a suppressor for 7.62 in the future, but it will be a .338 Lapua can. I witnessed one on a .308 bolt rifle in a match once and it was too quiet for the shot timer to pick up. Very impressive to say the least. Given that my .308 can will be a .338 and thus much larger than a standard .308, I am not willing to hand that off my AR.
Getting the most out of your can is important. I use mine on several AR's and also on my SBR FN PS-90, but I knew I would eventually buy more.
Full auto 9mm using subsonic ammo is not to be missed in your lifetime. It puts a new perspective on how quiet, quiet can be.

The three most important priorities are:

All leading brands will be within a few dB of each other and you will not be able to tell this with the human ear.
So much to learn.
Spoke to pat at silencer shop. Very informative and over all nice to chat with. Anyone have any direct experience with them? Seemed like a nice shop.
I'd have to agree with this assessment, with the possible exception of POI shift if you plan to leave the can on it full time.Quote:

Very jealous! I'm starting my paperwork soon!
This is what I am learning. Hopefully making the purchase in the coming weeks.Quote:
