Supressor suggestions

[CarlosDJackal]

I am seriously considering purchasing a suppressor for my SBR (it has a 10.5" LMT upper). I have gone through a few searches both here and in other forums about this but am not any closer to a decision.

So I was wondering what you guys would suggest for a suppressor based on the following criteria:

- For .223/5.56mm (AR-15).
- Quick Detatch (whether using an A2 FH or a proprietery FH.
- Final cost (including NFA tax) is under $1,000 (I just received a performance bonus :) ).
- None or minimal POI shift.
- Easy to maintain (clean).
- Comes from a reliable and proven manufacturer.
- A short as can be feasible (based on the previous criteria).

I know it's a tight one, but I was actually leaning towards a YHM Stainless Phantom 5.56 suppressor. Any suggestions or inputs would be greatly appreciated!!

The shorter suppressors will be louder. Here's a list of some QD cans to look at that will hold up well to a 10.5 and will fit on the muzzle and not reflex over the barrel:

AAC 416-SD
AAC M4-2000 '07
KAC NT4
Surefire 556K

I've shot them all with the exception of the newest iteration of the KAC can. They all have specific features, and one will be the right one for you.

I had much the same criteria with durability and light weight being paramount and went with the AAC 416-SD. It has a MSRP of $1,000 but can be had for less. It weighs about 15oz. and it's the lightest 5.56 can that I've ever held. You don't want to hang a lot of weight of of that little SBR as it will kill the handling of the package. The Surefire 556K would be another great lightweight choice that has good durability. All choices will be more than adequate and will be great buys with great warranties.

All the suggestions are within $200 of your range, but it will be a lifetime purchase, so pony up the extra dough.

[R1pper]

YHm makes great suppressors at a lower cost than most other companies and still have a lifetime warranty provided hou have your flash hider installed by a licensed gunsmith (keep the reciept incase there is a problem. They have the stainless one and chome moly one as far as sound reduction goes tehy are the same.

[davemcdonald]

A short can on a 10.5 LMT is still going to be loud. You will be able to skip the muffs when shooting but there will still be a very notable report. The set up does look cool though.

The SF 556K gets my vote.

We are now a class III dealer so let us know if we can give you prices on anything.

According to the Surefire website, I'll need at least a barrel that is at least 11.5-inches long for this to work. And what's up with the 1-year warranty when the other manufacturers are offering lifetime warrantees?

The M4FA556BK is the model you are thinking. The 556K is a model that doesn't reflex over the barrel, which is why i mentioned it.

You can actually use a barrel that is 10.5-20.

I never put much faith in those life time warranties. They always seem to find a way to screw you out of it.

When a rifle barrel is less than 11.5" some boat tail bullets do not properly stabilize in the few short inches as they exit the muzzle, thereby damaging the baffles and internal architecture of the can. Due to marketing and the popularity of 10.5" barrels, some manufacturers have stated their can will work down to 10.5" or smaller. In the 10.5" range, in 5.56mm caliber, the shooter should ensure they're using the proper weight bullet for the rifling twist of that particular barrel. If using 1/9 twist in a 10.5" barrel, it'd be a good idea to stick to 55 grain bullets thru the can. If using 1/7 twist, stick to the heavier bullets thru the can.

There's a lot of BS floating around - just be sure you get your data from someone that really knows, rather than from someone that heard about someone that saw a video of someone shooting a. . . well, you get the idea. There are so many variables that effect acoustics and sound that the simplest and most cost effective measure is running identical cans on the same day, in the same location, side-by-side for comparison. And, that only works in that situation. Electronic measurements have their own set of variables that I won't even go into here. Rain, snow, moisture on surfaces, hard surfaces, angles of reflected sound, distance from muzzle and on and on change the sound from hour to hour, day to day, position to position. Different people perceive sound variations differently when standing together at any given moment. Do your own research and come to your own conclusions based on real data. I'm not promoting or condemning anyone, any product or any method of comparison. Just be sure of your data. I have my cans and know from where of I speak - I'll stick to my choices and leave recommendations to others.

Shorter barrels are louder than longer barrels.

[rob_s]

I have a YHM 9mm can on order and I'm impressed with what I saw from them at SHOT. I'll be interested to see how long my order takes as they are really bragging about short production schedules.

I think that the AAC M4-1000 may be the best budget 5.56 can on the market but you may run into availability issues with them.

[CarlosDJackal]

Ah. For some reason they did not have that model listed on their website.

Grant, do you have information on it on your inline store? TIA.

Rob how long ago did your order the can? What one did you order? I know that they have been able to pump pistol can out fast, the longest parts was waiting for approval.

My dealer cashed the check yesterday so presumably it was ordered yesterday or today. I'll double check.

[R1pper]

No more than two to three weeks. Unless they are low on parts which I highly doubt. They get thier BATF approvals very fast. Ive heard of six months or more for KAC and others.

[Beemer]

I'm a new guy here, but I do shoot quite a bit of nfa stuff. I have an 11.5" upper for my ar.(with rll)-have used both the srt hurricane screw on can in .223 and the yhm .308qd phantom. I also use the phantom gd on v53(9.5"bbl) and a v51 with custom 10" bbl. The yhm .308 is very quiet on the 11.5 .223-very comparable to the dedicated .223 srt can with the enhanced ability to have less chance of baffle strikes on short bbls. because of the larger bore. Folks standing beside me have a difficult time telling the difference between the 2 cans. My srt .308 can is 5/8x24-very uiet on my rem. 700 hvy bbl(16.5") and minimal poi change, I also can mount that on the v51 just using the thread adapter-works very well with no baffle strikes using mil. ball ammo(semi and f/a), just as good as yhm qd 308 phantom. If you live nearby, would be glad to demo( I am not a dealer, just an addict!!) or come to the nc subgun match/shoot on Oct.27/28.-Beemer

[Nimslow]

I won't be able to shoot it untill thursday, but here is my Surefire FA556K, and some pictures of it mounted on my LWRC 10.5" piston SBR.

I'll let you all know how well it works out soon.

The Form 4 only took 34 days mailbox to mailbox.

If the 416-SD had been out when I purchased, I would have bought that....

Since the 5.56 is still pretty loud, even with the can, I would have preferred the shorter can, and smaller overall size.

15oz....:

[NightFighter]

What sort of criteria are used to decide what suppressor is good for an application? Is there some sort of comparison chart that a person can use to decide what suppressor is right for that person? How can a person tell which suppressors are the best of the rest suppressors?:rolleyes:

[SHIVAN]

"Lists" only scratch the surface of suppressor data.

The final, and only real worthwhile test for F4 transferables, is a live fire demo.

Once you know the cans that fit the size and mount types you want, there is no subsitute for live fire demos.

[RHR]

I went with the M4-2007 for my 10.5" LMT...

There are some charts out there. I think as long as you stick with a can made by OPS, Gemtech, AAC, SF or SWR, you will be GTG..

As Shivan said, each can will sound different to you and will also depend to a certain point on which ammo you use.

I agree completely and think on an 10.5" SBR the most important features in order are:
1. Weight savings to maintain the handling characteristics.
2. Length to again maintain handling in tight quarters.
3. Durability, as the 10.5 really beats on a blast baffle
4. Mount POI repeatablity and sturdiness.
5. Sound, most people will use these SBRs for home defense, and any can will be loud in your house no matter what.

This is what people mean when they say "buy the features that you want". I would only use a SF556K or 416-SD for a 10.5" AR based on MY requirements.

I barely notice the can is even on, 15oz. is LIGHTWEIGHT.

Check Ops Inc for their line of LE and military suppressors. They are one of the best out there, though probably expensive. Their cans push the freq's higher, above normal hearing range. They're made of stainless steel and you can easily add/remove water to increase noise reduction. I think they're guaranteed past 50,000 rounds.

[rsilvers]

Gun shot noise is broadband. I have seen it many times on a spectrogram and have published many 3D spectrograms of gunshot sounds. There are none I have found which mostly have ultrasonic energy and none which seem to shift frequency upward. There are some which attenuate lower frequencies more than higher frequencies, but this is not the same as frequency shifting.

[Chickenlittle]

My comments about Ops Inc. Frequency shifting came from what I read about their product. I will gladly yield to the experts on this forum, but I would like to know what experience anyone here has had with the Ops Inc product, pro or con.

I have had a 15th model for about a year now. Its been mounted on a 12.5 barrel, and its been through the paces.

First thing people say when they shoot the rifle is that they are surprised by the recoil reduction, and how smooth it operates. The muzzle is very easy to keep on target for follow up shots. It is *comfortable* to shoot indoors and out doors with no hearing protection (if you value your hearing, do not do this for sustained amount of time). It really tames the 12.5 barrel, while still balancing and not causing the rifle to be uncanny to handle

The mount is rock solid when everything is tightended, it is a very simple design yet really ensures everything is very concentric to the bore. Im not big into the "quick detach" mounting systems, I personally have no need for them, so I like having dedicated suppressors for each rifle, different purpose, different "mission", different needs/wants we all have..whatever floats the boat

It puts my 12.5 barrel just around 17.25 inches OAL, weighs somewhere around 17ounces I believe.

I have an OPS .308 3rd model sitting at the SOT right now waiting for the form 4 to get back...im a repeat customer :)

Good job on asking questions and researching what you want, and I agree with Shivan, try to hear what you want to buy before you buy it. I am a "total company" type of customer, I choose to support companies based on the entire product line and their company stance. There are companies out there that will never see my $$$, and there are companies that will see my continued $$$ because they make a great product and support their customer bases.
