Which AAC Brake on SRS .308 barrel for SDN-6?

Which brake to use on my new SRS Covert rifle?
22" 7.62 NATO Barrel.
AAC SDN-6 Can.

Not sure what you're asking. the 51T 762 brake is the only one from AAC that will work with your can. If you're wanting to know the thread pitch, the manufacturer should list it on their page or you can ask Desert Tech directly through email or phone. My 2 cents, I'd get a 51T flash hider since it's 308. The gun should be heavy enough that recoil should be manageable when you shoot it without the can. In my opinion, the brake on the 308 would be more unpleasant due to blast than the added benefit of recoil reduction.

It's 3/4 x 24 but the 7.62 brake w/ 51T only threads on 2 turns. The short answer is AAC doesn't make the brake for my can. I called AAC today & they said "rethread barrel to 5/8 x 24.
No thanks!
Just make the right brake.
The only reason for the brake is to attach the can.

SRS is trying to lock people into their can. 3/4x24 is a "bastard" thread for 7.62 suppressors, and muzzle devices. AAC is using the industry wide thread pattern. Re-thread, and enjoy your rifle.

Thanks for the suggestion but, I dont wanna rethread.
All SRS barrels are 3/4-24. SRS is a leader in precision rifles & AAC should support the barrels. Why don't they?
AAC Makes a 51T adapter in 7.62 but the threads are super deep.
If they could only bring the threads out all the way, I would be set.

The industry standard is 5/8x24. SRS should support the industry standard. Why don't they?

I certainly understand how you can think that, however; these barrels have been out for a while and they are what they are - just like many other manufacturers use unconvential threads (Accuracy Internationals are threaded M18x1.5). This line of thinking is irrelevant when we consider the facts - AAC wants to sell suppressors.
To sell suppressors AAC must have compatibilty as they're website indicates. The page showing my 51T brake in 7.62 has a listed thread pitch of 3/4-24 & only says it won't work on the SCAR 17. There is no hint anywhere on AAc's website that it won't work with the SRS.
I have the can & the brake but, no way to interface the barrel to can.
Barrel = expensive & brake is cheap.
If AAC wants to sell suppressors that fit my barrel, they need to design the proper brake, afterall; the people that buy this rifle are the same people who will buy 1 or more suppressors ( I have 6 AAC cans).
We won't re-thread our barrels, instead, we will find a suppressor manufacturer who caters to our needs and doesn't try to trick us with mis-information or lack of info.

What's happening at AAC? Did Freedom Group fire everybody?
Does Abiqua work for Freedom Group? It's just that your response is something you hear from a corporate clown with no vision.

Wow, jump to conclusions much? I just took exactly what you said and reversed the manufacturers. Based on recent history, I'd look somplace other than AAC for your silencer needs. Does that sound like a Freedom Group employee?

I wish you luck with your search for the parts you need.

To be honest, I can't understand why you are so hard-up on not rethreading your bbl.
It is neither uncommon nor frowned upon.
It is performed on precision rifles every-day w/o so much as an eyelash batting.
It will not lessen the value or prestige of your rifle.

With that said, it is your rifle and you can do as you wish.

The questions I have, for you, are:
1. Did you check to see what thread patterns were to be employed before piecing this kit together?
2. Were you or are you aware there are multiple 3/4x24 thread patterns used in muzzle device attachment?
a. 3/4-24-UNS-2A
b. 3/4-24-UNEF-2B
c. 3/4-24-UNEF-3B
3. You honestly expect AAC to supply all of their muzzle devices in every thread pattern available, and still turn profits and lead times?

I'm not trying to come down hard on you, but you are giving excuses to everyone for their opinions, that you asked for.
When, in fact, the blame rests firmly on the shoulders of the one responsible for procuring this: rifle, muzzle device, suppressor, combination.
It should have been brought to the attention of the DesertTech sales rep your intentions for muzzle device fitment.
If it was, and the AAC brake still does not fit, it should be the sole responsibility of DesertTech to rectify the situation. I'm sure you paid enough for Mfr-CS.

If after the above you still feel someone should make a QD brake to fit you rifle/can combo, then I suggest you go to a machine shop and commission the design and fabrication of one.
I'm sure the cost will be <5% of your total investment, thus far.

If you could, please, post a pic of your rifle, I love to see guns

I was looking for solutions not some unproductive baby babble.
Out of the many firearms I own, there has never been an issue attaching a muzzle device. The thread pattern was pretty straight forward. Unfortunately, I wasnt aware there are 3 different 3/4-24 patterns -

Even though, AAC should still state that it won't work on the SRS as it clearly does for the SCAR 17. Am I the only 1 who's had this problem?

I'm not having problems with the QD mount. Did you read about my issue with the 51T 7.62 brake? The QD brake works fine on the 338 barrel, in fact, the QD brake fits fine on the 308 barrel also but, the hole is a slightly larger diameter & I wont get the full potential of the correctly sized brake plus - I want to use the much shorter SDN-6 suppressor. You should also know that the suppressor threads on fine but stops after a couple turn as the base of the brake hits the base of the barrel stop. Did you see how deep the threads are in the pic I posted?

The reason for me not wanting to re-thread my barrel is obvious. SRS has been out for some time now & AAC makes a specific device just for the 338 why not for the 308? Why not at least say it wont work on the 308? Is that good customer service? Most every other manufacturer makes a device to work with my barrel - why no love from AAC? Brakes are relatively cheap to make & are required for the company to sell their higher priced suppressor offerings.

The simple plan to sell rifle suppressors is to research the rifle & calibers that would likely be complemented by a suppressor & after that little bit of math, my rifle / barrel combo comes in close to the top of the list.

Your entire rant has little in the way of solutions but, is more focused on putting blame on me or DT or whoever. This is the type of close minded thinking that prevents innovation & should be suppressed, unfortunately; AAC doesn't have a device for that either.
I still don't know which pattern I have (A,B,C) - do you?

The semi-permanent solution will be to use the adapter from DeltaP & a 5/8-24 brake then wait to see if AAC will make the correct brake for this barrel. It will look a little funny - I'll post a pic for your enjoyment soon as its all together.

[T-Rex]

Relax Francis
Honestly, I couldn't really make out the definitive evidence in your picture.
It doesn't fit, they don't make the right one, get over it.

Your say this yet announced your intentions to spend $ on an adapter?
Just go to a shop and have a custom SS or Ti mount made.

That escalated quickly. The website clearly states that our 3/4-24 brake is only for the M110. We do not make a 3/4-24 for anything else, because those are used primarily on precision rifles, and the 51T cans are not precision cans, so we do not offer anything for it. Also, most 3/4-24 rifles are going to be above a .308 from what I've seen. Our Titan Brake and Mk13-SD brake both work on the Desert Tech barrels.

[NickAAC]

To add to that, the Titan brake will work great on .308, with or without the can. No reason not to use it. Also, the weight of the Titan is the same as the N6, yet it is bigger and has more volume, and also is a precision silencer. I would much rather use a precision silencer on a precision rifle.

Thanks Nick,

I appreciate you chiming in as it really clears things up. Glad I didn't take t.rex advise to rethread. Didn't know the 51t's weren't precision devices.
No problem using the 338 brake on 308? Thought that because the hole was larger, it wouldn't divert the gasses out the sides of the brake efficiently but, that thought was not based on any real testing.
I'd like to speak with you - when is a good time for me to call in?

[Signature]

another shot with her panties off.
Titan-QD hooks up fine on the 338 barrel & based on Nick's advice, I'll take steps to use it on the the 308 as well.

[NickAAC]

That's a good looking rifle.

The difference between a dedicated .308 brake and the .338 brake is in my opinion so little that it's not a concern.

You can call in anytime and just ask for me, I'd be happy to talk with you. I will say though that Mondays are crazy and specifically tomorrow, the middle hours of the day I probably won't be available. Morning or late afternoon would be good though.
