Whats the general consensus on Surefire Cans? I am looking into getting the FA556AR. For the guy's who have them, any problems?

Thanks
 
Re: Surefire Cans

I don't own a SF, but have heard from those in the know that they are very good but expensive and kind of hard to get.

If you've got the budget and can find one, I don't think you'll be sorry.
 
Re: Surefire Cans

Not the quietest suppressor that I own, but it works great on my 12.5" SBR and 18" LMT MRP. Very little POI change and the mount works very good. I have not had any problems with mine.

Way cool! How do you like it, and what brand barrel?
 
Re: Surefire Cans

I have the FA556AR and have been pleased with it. I've shot it along side a few other cans and no one can really tell if one is louder than the other. POI change is minimal, I'm very satisfied with mine. Got it from ADCO.

I like it, it does what I need it to. I prefer my Ops Inc. 12th model and my AAC SPR/M4, but overall it is a very good suppressor.

The barrel is whatever barrel LMT uses for the MRP, which I believe is from Mike Rock, but I could be wrong.
 
Re: Surefire Cans

Good luck finding one. I've been looking for a 7.62SS for almost 2 months now, without success.

Because they sound better. When deciding on a suppressor, sound reduction is one of the most important qualities I look for.

I want one of those for my AR10, it seems to be the lightest fast attach .30 caliber can out there. When I got my 5.56 can from ADCO, they said even though they stock the 5.56 cans they could order me a 7.62 no problem. It sucks having to wait on a Form 3 and a Form 4, but both of my local dealers deal mainly in Gemtech crap.

Here is a video from a while back where I shoot my Surefire can alongside an SPR/M4 and a can made by a local Class 7.

I found one in stock. I am hageling on the price with them.

 
Re: Surefire Cans

The key to the POI shift on those is to have the compensator properly installed. The comp. to barrel clearance needs to be null. Factory barrels might not give the best results. It is best to have a smith turn the barrel to spec on a lathe and fit the compensator.

What if there is no comp?
 
Re: Surefire Cans

I have used the SF 5.56 and the best thing about them is the lack of POI shift with it or with out it.
With SS109 ammo and a stock rifle it did its job.
SF can sell to the Public now as long as your in a State that you can. The easy of putting it on and off is good too.
If on correctly you get no POI change.

Just what I have found.
I will pick one up in NV when I retire.

The can attaches to the supplied Surefire compensators. It is a fast attach/detach can, not a thread on.

Thanks, but I was hoping that you may have figured out that I have two SF's! Mine was just a general question for all suppressors.

Then it wouldn't be a SF QD can and since you own two, you already know that.
Apples to Apples, SF to SF, even then there are variances between performance of the same model, much less muddying the waters with an ambigious question related to other makers products.

As I stated before what causes a poi shift w/ threaded on barrels? Clear enough? I sincerely hope that wasn't too ambigious!
 
Re: Surefire Cans

[/quote]As I stated before what causes a poi shift w/ threaded on barrels? Clear enough? I sincerely hope that wasn't too ambigious! [/quote]

If you mean "ehat causes a poi shift with a thread on can/suppressor/silencer?

My understanding is that there are a few things:
1. the harmonics of the barrel are different with the can
2. the extra weight actually creates a shift due to "bending" or "pull" on the barrel
3. the mechanics change (ie. recoil management) which changes most people's shooting

Anyone, feel free to expand or correct as I am only a user. This comes simply from field use only. No test, just theory.
 
Re: Surefire Cans

Ok, for those that have the SF's how much barrel do I need past the gas block? On my 12.5", I have 2.75" from the gas block to the start of the threads. Is this going to be enough? I have seen various dimensions on the web, so its nice to have actual numbers.

Thanks,

Kind of my question too .. except I have the FA556-212 can and it is going to be used on 10" (yes 10 not 10.5) barrel with a standard front sight post base. Enough clearance once the lug is chopped and the comp/FH installed?

I'm waiting on my F4 for the can now.
 
Re: Surefire Cans

Why not throw in a 556FA to make it fair??? And does any of that add up to the difference of being heard or not heard?

<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: Turk</div><div class="ubbcode-body">And does any of that add up to the difference of being heard or not heard? </div></div>

Sound intensity is a logarithmic function.A 3db increase is produced by doubling the input power. An increase of 10db is perceived as 2x as loud.

<div class="ubbcode-block"><div class="ubbcode-header">Quote:</div><div class="ubbcode-body">M4-2000, 130.7 dB, +4.5 FRP, -35.3dB NSR, 16.9 oz, $895

As you can see it's about 7.6db diff..........this is closing in on being almost 2X as loud for 50% addition $.........and it's not even fully welded core,it's spot welded

Re: Surefire Cans

That some old pic has been discredited many times on here! Brand new AAC compared to ..... what a joke! How convenient to leave the bottom of the pic out! Stop drinking the Koolaid; but I really don't blame you since you gotta live w/ that tattoo Like I said compare apples to apples.Throw a SF 556FA in the mix! And next time you want to gloat about your own stuff; start your own thread!
 
Re: Surefire Cans

Surefires have been tested against AAC.....They didnt measure up to the less expensive AAC

Besides'...This subject has been discused...seems like you can never convince people with facts...More like Drama.

Surefire would be cool...If they gave me one for free.

Why the aggressive tone? Is this your thread only? Can anyone who doesn't agree with you not post as well?

The man asked for opinions and feedback. I provided numbers from DB testing, what's my AAC tat have to do with this?

I didn't attack you and call you a "kool aid drinker".

I didn't make this about you instead of the product in question.

Now if you have anything contrustive to add except personnal attacks the OP might want to hear it.



Again:

Other cans have and do perfrom better than a Surefire ( Surefire being almost 2X times as loud on a 10.5"), are better built( fully welded Vs. Spot wleded) and for cheaper( 50% cheaper ).

This is not an attack on Surefire or Surefire owners, it's simply what it is.



 
Re: Surefire Cans

To answer your real question, you will need at least 3" clear barrel in front of the gas block to mount a SF QD can.
 
Re: Surefire Cans

Actually let's talk about aggresive a little! Who's bashing who w/ BS comparisons. comparing a K model to the rest, showing pictures of a brand new AAC compared to a well used SF. God only knows what was done to it??? Show the bottom of the pic; where it is clear that they copied SF's design! Yeah I know SF didn't design it either, but so much for AAC being in the forefront! The fact remains we are humans and I can hear equally well the sound from SF and AAC! If AAC is so much better why did they get canned

from the FN SCAR rifle; after all they are less expensive?

look at their welds, they use spot welds..........that's not AAC fault.

As to what cans were metered, I didn't pick which ones would be metered. <span style="font-weight: bold">Regardles, the SF is almost 2X as loud as a AAC on a 10.5 barrel.</span>

If SF is right, then why did they just get thier lawsuit against AAC tossed?

Better yet wait to see what is on the end of that barrel! I'll have another pic for you a little latter! In the mean time perhaps you can explain why there is no comparison to the FA model?

Yeah.

Both the bases look like an OPS & the SF looks JUST like and OPS can...At least AAC had enough sense to fully wled their can......


10.5" is a pretty standard barrel..........it's not all Ar barrel makers had a grand conspiracy against SF....


I'm still waiting for a CITE on the FN dropping AAC?????????????????????????????????FN's catalog seems to say otherwise.........



A can that is almost 2X as loud, 50% more expense and not even fully welded is not "bashing".............it's simply stating the facts.

Are you saying that the Surfire suppresses better, is better built and cost less than the cans in it's market?

I don't take lightly to STFU! Now again if you want to post #'s that include comparable suppressor's; great! Why not test a SF FA to M4 2000? Let me guess they couldn't find a 14.5 barrel lying around? How much smaller is the K vs the M4 2000? How about those #'s? Showing a brand new AAC next to a used SF prooves nothing.

Sadly, the U.S. military issues a can that can't come remotely close to such performance. The average service life of the current issue <span style="font-weight: bold">SOPMOD can is barely 5,000 rounds</span>, according to a highly placed operator in a Special Forces unit who spoke to Combat Tactics on condition of anonymity. <span style="font-style: italic">"It's a piece of crap, but the manufacturer has political connections, so that's why we're stuck with it," </span>the source said.

The SOPMOD specification is for 10,000 to 15,000 rounds of service life. SureFire guarantees a service life of 30,000 rounds with its M4FA suppressor. <span style="font-weight: bold">"Honestly, we haven't been able to make one fail yet," said Dueck. "But we're being conservative and rating it for 30,000 rounds."</span>

The difference is in the high-temp aerospace alloys that SureFire uses in the suppressor, Dueck explained. "Durability is a huge consideration," the director of the Suppressor Division added. "I don't know of anyone out there who can compete with us on durability. We've put 1,500 rounds through a suppressor in 30 round bursts, just speed reload after speed reload. We broke the first M4 we tested like this on the fifteenth consecutive magazine, so we took the suppressor off, stuck it on another M4 and kept on with the test. <span style="font-weight: bold">Basically, we wrecked two guns and the suppressor had absolutely nothing wrong with it."</span> </div></div>
