AAC mount for scar 17s

Yep, no need to be confused in two different threads. :biggrin:

I'd like to correct some bad information. It was originally thought by the sales/customer service staff at AAC that the brakeout 2.0 had the same socket design as the flash hider, because it was designed not to use shims. We have recently discovered that it is not so simple. the brakeout 2.0 is designed with a deeper socket, and requires indexing off of a shoulder. Therefore, the flash hider is the only device that should be used. Will you get a strike because of the 2.0? I don't know. Maybe not. I'm sorry for the confusion though.

You should only use the flash hider on a scar 17. Also, no cyclones. I'm getting ready to make a blog post addressing the Scar 17 and the compatible silencers. I hope this helps some people out and avoids potential issues.

NickAAC - Yes! Please do it in a separate new post of its own. This will save you bunch of phone calls. For example, I have an AAC SCAR-H SD suppressor that I want to us on my SCAR 17. I would appreciate a posting of yours that might cover this application.

Was this information just found out? After calling AAC a while ago they assured me that the no timing feature of the brakeout 2.0 would work fine for a scar17. You seem like a great guy but all this misinformation is causing some people to go over to other suppressor manufactures

I believe we are going to try to make a video about it also. When I do make the blog post, I'll start a thread here about it so hopefully it helps a lot of people out.

Well that's just great.

I removed my Blackout off the 17s months ago and sold it. I put on a Brakeout 2.0 because AAC customer service told me it could be used on the 17s. (I still have the e-mail from AAC confirming it could go on the 17s with no timing/washers)

Will you guys take back my Brakeout 2.0 and send me a Blackout? Only 34 rounds through the Brakeout 2.0 and I think it's the least that AAC could do....ridiculous. Now I have to soak my barrel in warm water again to remove yet another brake. Let me tell you, something makes me uneasy about sticking my metal barrel in a small pail of water.

I finally made it out to the range two days before Thanksgiving to zero the rifle after installing the new Brakeout 2.0. On top of it all I'm going to have to go and re zero everything.

Now what about the Brakeout 2.0's on my 16s and AR with no shims? Good, not good what is the deal? Not happy here.......Cheez!

Is there a problem with the brakeout 2.0 on a scar 16 . I dont want to blow up my cans now

There is no problem at all with the 16. Only the 17. We just discovered this issue and I am trying to fix it by letting everyone know, when I saw this thread, I figured it would be a good place to start.

I am trying to stop misinformation caused by us from spreading, and make it right. I apologize for any trouble this has caused.

How is the recoil of the SCAR 17 without a brake?

If the Brakeout 2.0 is pin/welded, how does this affect things?

Soooo you don't know if it will strike...great. maybe you guys could do some official testing for the masses here eating popcorn. Better your cans than ours.

IMO this will not help the problem on the Brakeout 2.0 , sure you could acquire proper timing for the Brakeout this way but your torque spec. will not be correct and if running a can, the lack of a proper indexing off of a square shoulder will not allow the Brakeout 2.0 the ability to square itself up on a square shoulder. It would then be squaring itself off of the thread pitch, which we know would not be square to the muzzle crown, causing the possibility of a baffle strike if running suppressed. Not to mention reversing this process ( pinned and welded ) is not always a simple process resulting in, worst case scenario, having to cut and rethread your barrel. Now you are likely to be dealing with a SBR or buying a new barrel at 1K plus. I would try to avoid this ! Just my .02 .

Can anyone speak as to if the oem locking nut is used on the brakeout 2.0 ,could baffle strikes happen with that?

NO muzzle brake/suppressor QD mount on the SCAR 762 family of weapons is recommended by Stryker Enterprises due to the insufficient shoulder on the SCAR barrel profile.

Flash hiders are A-ok on the SCAR 762 family of weapons.

No OEM lock nut is to be used when mounting a flash hider/suppressor QD mount on the SCAR 762 family of weapons. Simply thread the FH QD mount after cleaning the threads and applying Rocksett. Then torque to recommended specifications.

Muzzle brakes are A-ok on the SCAR 762 family of weapons long as they are not used as mounts for suppressors due to the risk of baffle strikes being above 50% and longer suppressors are more at risk that "K" suppressors.

Jim, why would flash hiders be ok and not muzzle breaks? It is baffling me HA! as to how all these guys mount cans to their scars...

First off, calm down. Second, the rep from AAC just told you to not use the Brakeout 2.0. and specifically why not to, "the brakeout 2.0 is designed with a deeper socket, and requires indexing off of a shoulder".

This has been ::0::. If you want to know, search for scar 17 and suppressor. Jim has answered this question many times as to why and even damaged an expensive Surefire can to prove the point.

calm down? I have a substantial investment in an aac can/mount for this weapon and naturally I'm trying to figure out if it's noncompatible. I'm not trying to stir the pot.this is the first I've heard of it. there is no sticky for do not use this on scar 17, and aac is just now coming around to fessing up. I came aboard this forum during the heat of all the ban talk and didnt get read into all the in's and outs. So please excuse my descent.

Wow. I have a brakeout 2.0 on my 17 and have been shooting it with my sdn-6. Did this after speaking with the rep at AAC. What do I do now? What is the trick for getting the muzzle device off after using rocksett? I guess I the only option is to change to the Blackout?

People have different methods for this. As much as I hated to I went with the advice of soaking my brake & barrel in a shallow pail of hot water for about 20-30 minutes. After that it broke loose in the vice with a fair amount of torque.

I read the original post here where it said it was OK to use the 2.0 on the SCAR17. When I installed mine I thought it seemed very odd that the face of the muzzle did not bottom out on the inside of the 2.0 but instead the back hit the thin shoulder on the barrel. What a PITA.
