i know its a very open question but i would like to get some opinions.

what is the best performing flash hider? by that i mean ,which ones have the smallest flash signature?

if the flash hiders perform different on shorter barrels then what is the best flash hider for a 10.5" sbr?

these 2 ......... AAC Blackout , Smith Vortex some say one is beter than the other but they are both great products.....

As for a 10.5 sbr.... dont have any data on that

Both of the ones listed above wrok very well. The Smith Vortex has been the standard in flash suppressors for years.

Of course, on a 16" or 20" AR, the A2 FH is quite sufficient for most purposes. On an SBR, I don't think any flash hider is going to be truly effective, and you also have the increased blast to contend with. A suppresor is your best bet here.

As stated above. I used a Phantom II on my 10.5" before I went to the Levang. You won't kill the flash on a 10.5" without a suppressor.

my plan is to build a sbr and then get a silencer for it. but i cant afford to buy both at the same time. so in he mean time i would like to run a very effective flash hider until i get the money for the sound suppressor.

i will probably actually buy the flash hider now and put it on my 16" upper until i get the sbr stamp and then build it.

how long is the aac blackout compared to the a2?

The AAC Blackout on my 10.5" cuts the flash down to just a faint blue signature. Indoor range, lights off (some ambient light). The flash was almost unnoticeable while shooting, barely noticeable when looking at it from the side about 15 feet away. It was there, just not a bright, annoying fireball. Very happy with it, I think it's the best you can do short of a suppressor. I'm sure a Vortex would be very similar.

Do any of the new combination Flash hider/ brakes or flash hider/ comps work as well for flash hiding as the Vortex, or is there a trade off?

i fixed the link. has anyone tried it? ^

my research seems to show that its a terrible flash hider because thats not what its designed for.

Drew, that PA comp is probably not gonna do much for flash suppression––anything sold as a "compensator" is usually going to do different things than a flash hider.

If it were me, I'd go with a Vortex, Phantom, or just leave the A2 FH in place until I could afford the can.

Can, Blackout, and Vortex in that order. Have all three, and have tried several others, including with NV; anything else doesn't come close at flash suppression.

thatsgood to know!

one last question. has anyone tried the aac breakout? its supposed to be a combination muzzle break and flash hider.

Haven't personally tried a Brakeout yet, but the fairly consistent word on the Suppressors Forum is that they are neither particiularly good at flash suppression nor muzzle braking.

It seems that most folks who are using them are trying to protect blast baffles on cans used with very short barrels [10.5" or less].

i lied, i have another question.

how long are these flash hiders your mentioning (standers and suppressor mount versions)? which ones can be welded on to add enough barrel length to a 14.5" barrel to make it the legal 16" and not need a tax stamp?
murderman  [Team Member]
10/2/2010 6:08:35 PM
Vortex adds 1 5/8", and Blackout MITER adds just under 1 3/4". Cannot comment on Blackout non-suppressor mount, as I don't have one in front of me to measure.

I remember watching the BE Myers video of their flash hiders and I was really impressed by it.

The AAC Blackout is the way to go. It is the most effective flash surpressor I have even seen tested, and I have seen many. At best the Vortex is equal in certain comparisons.

This is what I have used on 11.5" barreled rifles in the past.

Agreed. Aside from complete suppression, the Blackout is a more robust design than the Vortex IMO. The AAC does not ring like a tuning fork after each shot.

I am inclined to respectfully disagree with your last statement; open prong FH's all seem to exhibit the "tuninig fork" effect to varying degrees, since that is what they all fundamantally are from a harmonics prespective. My several Blackouts all "ring" with or without their respective cans, if one chooses to listen for something that is otherwise insignificant to overall performance, i.e. flash suppression.

Brownells has a video on youtube testing several flash supressors. The Vortex was by far the most effective of those tested.

I am guessing that the Blackout must not have been included in that test?

Crazy talk as I have used tons of brakes and F/Hs and this new brakeout is easily the most impressive muzzle device Ive tried to date. It blows the fsc556 clearly away imho as well. One who is a fan of a BO should see the inherit ability for these flash suppress and while they will put out a bit of flash over say a vortex or normal BO, this thing is really a high efficiency brake and the large and even 12, 3, and 9 oclock port keeps the gun in line and down on point and unlike the fsc556, it very nicely patterns the exhaust and creates no where near the disturbance in the surrounding environment like the fsc556 and some others.

Another plus is for it being a high efficient brake it effects accuracy zero, whereas something like the new battlecomps are expressly written to not use on accuracy geared guns. The TTs would also prob. affect it too.

I'd sure like to try out the Brakeout firsthand whenever AAC decides to manufacture one for my SPR/M4 or SCAR-H SD.

How do you like the spr/m4? What is the major advantage if it? I'm intreagued by the design. At first I thought it would allow a shorter overall length with the silencer attached, but the silencer is longer than the other aac silencers so it's really only a half inch shorter oal when on the gun. I believe it may have more decible reduction though.

I like the 5.56 SPR/M4 just fine. It apparently meters as good as most. Since I prefer the substantial relative velocity improvement of a 12.5 versus a 10.5, a reflex can seems to make alot of sense FOR ME. YMMV It is the same OAL as an un-suppessed 16" w/FH.

The MITER mount allows tuning of POI shift, but that is a double-edged sword, in that indexing in one of five positions versus a single position takes some practice in the dark, with or without NV; it is all about muscle memory.

I don't know that there are necessarily any "major advantages" versus other options, but the combination of features seems highly desirable FOR ME.

The SCAR-H SD is scary quite on the .308 bolt gun, but there is more-than-average gas blowby at the mount. It also has the same MITER pros/cons. On the 6.8 SBR, it isn't all that impressive. My dealer has a 6.8 SPR/M4 "with my name on it"; I guess that I should give him some $$$, and get the paperwork rolling.

Back on topic, the Blackouts are superb at flash suppression, even on the SBR's without the cans and using NV.

Gratuitous porn:

I'm leaning towards a 14.5" mid length with a permanently attached flash suppressor. If that's the rout I go then I need to decide what silencer i want so i cam buy the proper flash suppressor/silencer mount. I'll build the upper and buy the silencer later.

The m4 1000 mounted on the gun adds 7.575".

The spr/m4 mounted on the gun adds 6.65".

On a 14.5 middy, an SPR/M4 would be pretty sweat; it would be just about the length and weight of an un-suppressed 18" SPR.

If you plan on getting a suppressor anyway, than why not simultaneously do the SBR paperwork / stamp for only a few more $$$ than perm attach?

I thought about doing that. But to build a sbr I believe I will have to start with an unassembled lower receiver that has never been built into a rifle. So I'll have to invest $200 more for the stamp, then about $350 to build the lower, plus I'm not sure how much for the engraving.

14.5" is a pretty well balanced barrel length anyway, and I really like the mid length gas system and little longer rail that goes with it.

I haven't completly decided what I'm going to do for sure yet. This thread has made me decide that I want an aac blackout flash hider and eventually an aac can. Now I need to decide what barrel length and silencer I want to do.

My thinking is I can do a perm flash hider/can mount on a 14.5" with a suppressor soon after. Then I can build a sbr later and buy another flash hider/can mount for it. I'll always want a 14.5" anyway, it's not a big deal that the flash hider will be perm attached.

Incorrect, you can SBR any receiver, rifle, or pistol. The restriction you reference is only applicable to building a Title I pistol.
