Suggestions on suppressors on the market?  Was looking at the Gemtech G5 and M402.   Digging on youtube seems the G5 is more silent.  Looking to get one for a 16 inch middy I just picked up.  After I get my paperwork back.  Thanks in advance for suggestions/opinions!

IMO the best can is the AAC SPR/M4.  Best flash hider in the can mount, adjustable POI shift at different mount indexes, super fast 1 turn mount, 1 of the top 2 mass produced cans for suppression (the other ebing the Ops 12th model... all other cans are louder than these two), one of, if not the most, durable cans made, relatively light for a reflex can, low back pressure and the only negative is that it wont fit on super short barrels with a fsb close behind the muzle or a rail close behind the muzzle.  I have mine on an 11.75" barrel with a 9" rail.  A 11.5" barrel requires a carbine rail and short gas block.  It can fit a 9.75" barrel with a pistol gas system and carbine rail.  What it wont fit is a 11.5" barrel or shorter barrel with a standard FSB in the carbine position.  I did have a baffle strike due to a bad round and AAC took care of me so customer service is excellent too.

Try the Suppressor Fourm IMHO, YHM, but that's me

More silent...that's pretty funny.

You may or may not know that an AR-15 with the best suppressor money can buy will still be very loud and you will still damage your hearing if you shoot without hearing protection. Video cameras can't really capture the actual full sound of a suppressed rifle.

Now that that's been said, are you looking for a direct thread on suppressor or a QD suppressor? If you have more than one AR, you might want the latter. YHM cans are supposed to be nice for the money. Pretty much every brand of suppressor has a lot to be said about it, but all of them work just about the same. I've heard stories of Gemtech HALO cans loosening during long strings of fire.

For me, the main concern is weight, build construction, and cost. I wish a company would make a short, fat, thread on reflex suppressor for under $600, but I doubt anyone will any time soon.

I got a G-5...  no complaints here really, but do your homework on the G-5 before you buy.   Gemtech customer service is great and it's a repairable can if something bad happens - baffle strikes etc...  Not that I have ever had one in ...thousands of rounds.  

Check out Ops Inc. cans.   Also look at surefire, but be prepared to pay more.  

+1.

I recently shot... then immediately purchased two
Surefire cans (556AR and 212).

I had the AAC M4 2008, SPR/M4 and Omni. They all were very good (especially the SPR).
However aside from their good suppression, the M4 2K and SPR had a lot of blowback.

The reason I went with the Surefire instead was they had about half the blowback...and other reasons.

The thing that stuck out was if I fired a few rounds and took the mag out and ejected the chambered round,
the mag, rounds in the mag and the ejected round all looked extremely dirty. I didn't pay much attention to that
until I shot the Surefire cans. The mags and loaded ammunition (including the fired brass) all looked pretty clean
for being shot suppressed.  I decided that must also be an indication of how much gas is being blown back
into the receiver.

Also with the Surefire cans the attachment seemed to have less issues with the teeth locking/timing to the
flash hider than the M42K.

I think the AAC cans may have suppressed a little better but the Surefire can had the best balance
between suppression, weight, attachment and blowback.

Can you describe the issues with the lock/timing of AAC cans?

Just my opinion from my experience with my M42K...

I found that about 1 in 4 flash hiders I came across would allow the suppressor to tighten up fully and have the
rathcet latch fully engage the teeth on the flash hider, With the other 3 out of 4 the suppressor would tighten
up but the ratchet latch would not be locked down. By rotating it counter clockwise you could could get the
latch to lock down but it left a little wiggle in the can.

This has been discussed before and AAC has said the can
would still be within tolerances and it would not be an issue. I do not dispute that there would be no concern with
baffles strikes. I found I had minimal POI shift with the can tight and locked, but if I backed it off one I had some POI
shift...for me appx 3-4" low right at 100yds.

As with the SPR/M4...I found with most all flash hiders 2 of the 5 positions would lock down tight.
It varied from hider to hider but all I tried 2 of 5 locked good. In the locked tight settings I had
minimal POI...I tried this out to 200yd

With both suppressors, tight or not, the suppression was very good (aside form the blowback)

I just found the finer teeth on the Surfire 212 flash hider allowed a better lock up. For me a can that locks down tight
seems to have the least POI shift...if any. I'm sure there are other factors to POI shift.

SPR/M4 is the way to go.

With my m42k '08 it tightens to almost latching over on the last notch but doesn't quite make it, so it backs off the maximum that it can before latching.  This allows it to wobble around which I do not like at all.  I know that it is within spec to avoid a baffle strike but holy shit I can't imagine a pound of weight wobbling around the muzzle can be very good for accuracy or repeatability.  I will probably order 4-5 mounts from somewhere to find one that latches tight without the wobble then sell the rest.

Huh.  Thats the first I ever heard of the mounts having problems locking tight.  
I guess I'll have to see how mine secure when they get here.

For the price, YHM w/ Quick Detach (QD).  IMO.

So how do you cut the sound from a rifle without lowering the muzzle velocity below the speed of sound??

sdodd

You contain the blast that takes place outside the muzzle from the sudden expansion of gases.  And of course, you'll still have a supersonic crack, but that is a small percentage of the overall noise.

WI57,
        Talk your wife(soon to be) in to coming down to the Dells for the weekend and we can take your cans out and see how they fit and shoot. Hopefully your forms will turn up down here soon.

I find it hard to believe an SPR/M4 had a lot of blow back.  I have shot several Surefire cans and not noticed less blowback than my SPR/M4.

Fatter means more volume, and thus the baffle can be spaced closer while maintaining the same volume, theoretically making it shorter. It's all a theory; I've still got a year before I start working on my ME degree.

May I ask, how your gun is setup?

I kinda look at this a little differant...

Isn't the silencers main job to be quiet?

If that was the only consideration we'd be seeing 2" diameter 10" long 45 cal cans, and bigger for .223/.308.  If bench guns were the only consideration, then size/weight/blowback wouldn't matter.  Personally after a day of shooting, I would take an additional 2-3 db to not have gas in my face and lots of cleaning in actions/magazines.  Quiet is good, the full package - at least to me is better.  If I wanted hush puppy super quiet, I would form 1 a 3" diameter 14" long .223 can and man would that be quiet.  Of course then I wouldn't want to go hunting/training/3 gunning with it on the end of my AR15.

Edit:  In answer to the OPs question, Ops Inc hands down.  Other offerings from Gemtech (I have the G-5 and am very happy with it), YHM, SWR, AAC and other manufacturers are nice also.

This question is best answered by silencerresearch.com.  $30 for a year subscription and it has in depth testing and comparison when it comes to reduction, weight, size, blow back, internal volume etc etc etc etc etc.

I agree.

 
































 

I used the same logic to settle on a Surefire FA556-212 yesterday.  Figured if I wanted Hollywood quiet, I'd find a different caliber to shoot.  I just wanted to dampen the report of the AR a little and keep the weight and overall length down on the front end of my 16" gun.  I handled a YHM suppressor next to the Surefire.  I swear that YHM must have weighed over 2lbs.
