6.8 flash hider

[olemiss]

I recently built my first 6.8, with a Kotonics barrel I got from Owenslee, and hope to sight it in tomorrow. I found a RRA 6.8 A2 flash hider from PK Firearms and put that on the barrel. I also have a barrel coming from WOA I ordered last November and am looking for another 6.8 flash hider but cannot find one. What are you guys using?

[trevorjb22]

I believe AR15perf is giving you an option on their barrels:
An YHM Phantom Flash
An Armalite 2 Port Muzzle Break

And I have seen a PWS FSC30, but I dont believe they are offering the last one on their new builds.

The Smith Vortex gets very good reviews. Its threads are 5/8 X 24 X .730”.

+1 on the Vortex from Brownells.

the PWS FSC30 is an excellent compensator, I have not seen any muzzle flash from mine and everyone is amazed how much it dampens the recoil its like shooting a 22

The Vortex has the annoying (to me) trait of having a high pitched tuning fork ring when you touch something with it. I like the Pheonix flash hider and Vltor is suppose to release (past due) several models threaded in 5/8" X 24. Really any of them work, it's a personal preference (looks cool) type of issue. The FSC30 creates significant side by side blast which will annoy your neighbors on the firing line (looks cool too).

I call that the anti Fudd effect

Has anyone tried the QC comp on a 6.8. I was looking for a new flash hider or comp as well.

I am trying to understand the depth of answer you are looking for and comparing that to everyone's response so far. I am fairly new to this stuff too, but I think the generic answer is a .308 flash hider. There may be 6.8 specific flash hiders out there (and likely compensators since that is where the exit diameter is most important, but at least one of the alternate muzzle devices being offered for the Extreme are 30 caliber devices. As an example, the alternate comp/flash device is the YHM-3080-5C2.

Hope that helps and is not overly simplistic. I'm sure if I am in error, others with chime in with corrections.

Bullseye,
Are you sure it is not the YHM # 3080-5C1 Phantom comp/ flash
thats what Constructor put on his thread. I haven't looked to see if there is even any difference between the 5C1 and 5C2.

[bubbahcpd]

The PWS FSC30? I would like to see it, any information on where?

[trevorjb22]

Heres a link.

[bubbahcpd]

Thank You. Man that looks like a fire breather. Not what I want for a duty type break. Will have to keep that in mind though for purposeful use.

One has a smooth rim(exit) the other has tacticool teeth

http://www.rainierarms.com/img/shop/product/68db79d77e385a18784c693993daa33c.jpgThe popular Phantom Flash Suppressor has been redesigned to work as a muzzle compensator while maintaining the excellent flash hiding capabilities of its predecessor. This 5 port design has no downward facing port which helps eliminate dust problems when shooting in the prone position. The 5C2 keeps the aggressive front end used in hand to hand situations. For threaded barrels only. Includes crush washer.

I run a Phantom 5C2 and am forever sold on them... not so much as a recoil or flash reducer but as an all around "muzzle device"... it has a striker tip for non lethal or entry applications... the 5C2 is different from the 5C1

these cost about 30.00 or 10.00 extra on your xtreme order :wink:





Primary Weapons FSC30 AR10, 6.8SPC Flash Suppressing Compensator
This FSC30 Tactical Compensator has all of the compensation of the standard DNTC308 compensator combined with enough flash suppression to keep the flash out of your optics and line of sight.

This unit is 2.75" in length, .960" in diameter and is threaded 5/8x24

Costs 100.00 though

Tim's site has the 5C2. In either case, the "3080" in the part number indicates it is a 30 caliber flash hider/compensator, not a 6.8 specific unit.

I assume those are from 5.56 mil spec ammo testing that has a flash suppressant, most commercial powder and ammo does not. Nice comparison though

[BLACK LION]

CORRECT bullseye... its a .308 unit with the applicable 6.8 thread pattern.. or .30 cal

I've use the PRI/MSTN QC Brake on my 6.8SPC in the past and although it was very effective as a brake, it had a ton of side blast and it was loud. I currently use the FSC30 and it is much better. Less sideblast and not as loud. The FSC30 is the only muzzle brake that I would use on a duty AR. The Troy Medieval Brake is also another option for a muzzle brake and I like it because it almost looks like a normal muzzle device.

If given a choice, I would use the Smith Vortex if I did a lot of night shooting and the regular A2 flash hider for anything else. For the 6.8SPC, I wouldn't use the YHM Phantom because it is HUGE.

[diving dave]

I'm kinda leaning towards that Primary weapons system comp for my recon build...I've read a few reviews and it looks good to go.

[trevorjb22]

Can someone give the measurements lengthwise between an A2 flash hider and the Phantom 308 FC1 or FC2.

[trevorjb22]

I also forgot, Can we get a measurment on the Vortex Flash. And is it made by YHM or Smith?

[Tim_W]

The issue with 6.8 muzzle devices is all the manf went the cheapest not the best perf route possible other than PRi. They all simply have you using the much bigger than need 308 s stuff which has 40% great powder flash than a 6.8 which has about the same as the 5.56. what should have been done is 5.56 devices should have been reamed and threaded for the 6.8 with them reaming it big enough so if it was accidentally put on a 308 it would not cause a hit but be not as effective. Personally for ordering I believe the A2 is the best general choice of the option we offer. After that I would decide brake or comp and then get the 5.56 model you want and have a smith or yourself ream and tap it to 6.8. That will get you a much better sized device and the proper function.

This is a good idea, but if you go this route, make sure the flash suppressor/comp has enough material so it doesn't get too weak after reaming and retapping. It is a good route to go if it's a viable option for the flash suppressor/comp you choose. I have a Vortex on my rifle (.308 model). It's a whole ounce heavier than the 5.56 Vortex, and a whole ounce has a big effect on the balance of the rifle when it's 18" from the reciever (the old fulcrum and weights explaination of torque, I can actually feel the difference in the balance of the rifle with the flash suppressor off and on it).

Here is a Brownells video comparing several different flashhiders. After watching it, you'll see why I only use Vortex FHs on my rifles.

I've been using the DPMS flash hider. I like it because it is smaller in diameter than the YHM, though of about the same length, yet gives a similar look. Looks very nice in my opinion.

[coppahed]

Mark 21,
Cool video. I didn't notice much difference Between the Phantom and the Vortex. Did you?
The vortex sure looked like 0% flash though. Thanks for posting that video. :)
