I have convinced my self that I need a silencer. I understand that they are not movie quiet but I want as close as I can get.

My criteria is as follows.

Type of weapons: AR-15 16" carbine gas system. AR-15 10.25" pistol (I may turn upper into SBR later), and AR-15 20" rifle. All are in 5.56.

I want to be able to move the silencer from weapon to weapon. So I will need an adapter on each firearm.

I am a function over form type of guy. The firearm must maintain its reliability. What type of changes will I need to make? Will I need to change buffers?

I have heard that the back pressure will blow gas into your eyes. Any truth to this? Will I need a gas buster charging handle?

Any input is greatly appreciated.
 
Sound suppressors are very nice :evil:

I like the Fisher/SEI can and the DC Vortex from SEI.
Mine is a .30 caliber can that works just fine with 5.56 as long as you install a DC Vortex.
You will definitely want to install a Gas Buster on all of your ARs.

Yes sir :cool:

"Here you see our Std. weight .30 cal. suppressor on a M4 with our Vortex being shot at 500 meters.
They found that there were no change of bullet impact at that distance suppressed or not, we were very happy as were they."

I have an AAC M4-1000 that I just shot for the first time. It used a QD mount so it is swappable. Yes it is nice, I was pretty amazed.

I would say it was about as loud an a heavy duty nail gun.
Yes, it blows even more crap into the receiver of the rifle.
 
Mot45acp SEI's web site says its only available to the govt, law enforcement or FMS

SEI's web site also says...

" The Smith Enterprise, Incorporated-marked line of suppressors are only available to the US Government, Law Enforcement entities and through Foreign Military sales (FMS) programs. SEI-marked suppressors are not available on the civilian Class III market.
However, civilians living in jurisdictions where possession of sound suppressors are legal can obtain DC suppressors marked Fisher Enterprises, Inc. Civilians interested in acquiring DC suppressors should contact Mr. David Fisher directly at 602 615-7777 or via email at [email protected]. "

OK, most reflexing suppressors (one that have an expansion chamber extending back over the barrel) are out if you plan to use it on both a 10.25" pistol and a 16" carbine. Second issue is that a 16" carbine already has a longish dwell time, a suppressor is going to magnify that effect. You will definitely want at least an H-buffer and possibly an H2. You'll need to play with buffer weight to see what works; but it will cycle a lot harder with the suppressor.

Adapters add up fast and can be pricey in their own right. I'd take a look at the cost of the individual adapters when pricing the suppressor.

A Gas Buster helps (and is just a good charging handle regardless); but most of the gas is coming back through the chamber and ejection port area, so the Gas Buster won't solve the problem. It will just mitigate it slightly. If you shoot suppressed, you are going to get a little gas in the eyes - gas piston, roller-delayed blowback, direct impingement, doesn't matter. Wear protective eyewear and get used to it.
 
i have a number of suppressors, including a smith/fisher enterprises suppressor. it's ok, but it's heavier than any of my other cans and the "quick attach" over the vortex FS totally sucks. I thought the QD was cool at first... until I used it. ugh. Also, mine does exhibit a reasonably significant POI shift.

I will say it's solid though. I shot mine off the end of an ar15 last summer and other than getting a little mud in the end, it survived the flight apparently none-the-worse.

YHM is good value, especially for just hobby/range use. not as good as other cans, but not as expensive, and it doesn't come with any unnecessary drama. (I have 1)

Knights makes an awesome can. (I have 2)

i was itching to get a surefire brake/suppressor combo, and also a FSC556 brake/gemtech combo... but to be honest, i kinda lost interest in suppressors lately
 
taliv, yours is the very first complaint of a POI shift that I've heard about... it sounds like your AR is sick because the interface of the DC Vortex and the SEI can is rock solid. How in the world did you shoot the suppressor off of your AR? I have never experienced a single problem with my DC Vortex set-up on an AR, M14 or AK and you will note that the M21A5 Crazy Horse equipped with an SEI can recently out shot the KAC rifle with their can.
 
heh

yeah. some perspective: recessed target crowns exist because slight imperfections in the end of the crown will change POI and group size. Barrel tuners exist because simply adding or removing weights at the end of a barrel will change the POI and group size.

yes, the interface is rock solid, but that isn't the technical problem they have to overcome.

and mine isn't a 'complaint' per se, as I expect ALL cans to cause a change in POI.


as far as m21 stuff outshooting KAC rifles... I've posted pictures of groups shot from my KAC rifles. Feel free to post some of yours.


btw, i shot it off by simply not screwing it on. i slid it over the FS with the little wings disengaged and collar off. no big deal

Considering this, would a mid length gas system be more reliable? Or a little less rough on my gun?
 
Yes.

I have a YHM stainless phantom 556 fast attach in stock as a demo. I'm very pleased with it. Their fast attach system is rock solid. I've done several full auto bursts and mag dumps through mine and it never loosened a bit. If I were able to own a suppressor as an individual in MI, I'd transfer the phantom to myself. I like it a lot.

A semi auto has to be tweaked to run optimized, as was stated above. Most guys that are on a budget buy a .30 caliber suppressor and just attach it to their smaller caliber guns. Makes sense. Theirs only a 1-2db difference than using a dedicated .223 suppressor on a .223 gun. Your ear probably won't notice the difference. For a tight budget, get a .30 caliber suppressor and use it for .30 and under centerfire.
 
In research I have seen the terms "wet" and "dry". What does this mean? Dunked in water? Oil?

I like the midlength better for suppressors and 16" barrels; but even in a midlength you are going to notice the difference in cycling with an increased dwell time.

As for POI shift, I've seen the same brand of suppressor have different POI depending on what barrel it was attached to. If you get zero POI, then good deal for you; but I wouldn't expect it as a matter of course with any suppressor.

Liquid makes a suppressor more effective. You can use water, CLP, and various other liquids although you have to remember that whatever you put in there will be combining with all the powder residue in the suppressor and sitting for a long time afterwards. A few drops of CLP will make my OPS Inc. 16th model noticeably quieter for several shots; but it also increases the "gas in the eyes" thing for the next hundred or so shots.
 
The M4-2000 is the best silencer mentioned in this thread. If you are about to drop $800+ on a silencer you would be well-advised to visit www.silencerresearch.com and pay the $30 for a premium membership. He has reviews and sound meter data for most popular 5.56 silencers currently on the market. It could save you from making a very costly mistake.
 
I agree. $30 is money well spent to help fund the research. It's well worth it to simply learn more about suppressors.
 
As noted, adaptors can e expensive and hard to get sometimes. I'm waiting for give AAC a c-note for an adaptor. Yeah $100 for a freaking flash hider with threads on it.

I had no clue the sound difference from shooting 556 out of a .30 can was only a few bd. Any technical data to back this?

Yeah, that puts everything into perspective.


Mot45acp, contact Mark at Polite Society Inc. and discuss your wants and needs.
He has a ton of hands on experience with many different makes and models of suppressors for all sorts of weapons.

I happen to like the SEI/Fisher can, but you may find something that better meets your needs.

I'm starting to lean towards the YHM .308 stainless can. The only thing I've heard negative about them is the weight.

That they are actually quieter on 5.56 than the 5.56 can. The mounts are compatible with 1/2x28 and have an adapter for the M1A. That they are built like a tank.

I think its gonna be the 6 mounts that are gonna eat my lunch or the oddball threads on my FN PBR.

Thoughts?
 
The standard thread for .308 cans is 5/8-24 tpi. What's on the PBR?

A .30 can on a .223 is a bit louder than a .223 can on a .223.
