Our new Brake Attach (BA) line of silencers is ready. These were developed to meet the needs of customers who require a muzzle device when shooting without the suppressor. We haven't found a "quick mount" on the market that meets our accuracy and repeatability requirements, so we developed the BA series to mount over our brake and provide the same repeatability as our direct thread attach suppressors, like the 30P-1. The 30BA features a conical shoulder for rock solid POI repeatability and to make sure it never comes loose. These use the same baffle stack as their direct thread-attach counterparts (30P-1 and 338P-1) and are just as quiet.

The 338BA suppressor can be mounted on the 30BA brake, but the opposite does not fit for safety reasons. The 30BA brake is a single chamber design, while the 338BA brake is a double chamber design.

I saw this Friday

Sweet ... I like how the large calibers get the two chambers which won't fit the other way around so you can't accidentally use a 30 cal can on a 338, only a 338 on a smaller caliber.

This has been in the works for a while. Here are two prototypes that were fielded at last year's Steel Safari. The guy with the DTA gun placed high .308, 5th overall. That's the .338 suppressor on his gun. Everyone got to shoot the Barrett as it was the dedicated side-match rifle.

Re: Thunder Beast Arms - New Brake-Attach Suppressors

Zak, I have a 338BA pending right now and I just received the mount for my AIAX .338LM, After removing the factory break, it looks like there's not enough thread on the barrel ( aprox. .375) to properly support the mount/suppressor. how much of the barrel needs to be threaded in your opinion to make this work?

Re: Thunder Beast Arms - New Brake-Attach Suppressors

Hi,

I just measured my AI .338LM barrel (2005 date stamp) and it's 0.479" from shoulder to muzzle, and the threads are approx 0.36" long (or 6 threads). That's basically identical to the other factory or GAP AI barrels I have in the safe, although some of them try to squeeze another thread in the root cut area. So it sounds like yours is the same as all mine. The threads are large and have a lot of holding power.

Just curious, does your AX 338 have the UK barrel, or a US barrel fitted by AINA? If the latter, what are the muzzle threads?

Re: Thunder Beast Arms - New Brake-Attach Suppressors

UK barrel, I bought it from Randy @ MHSA. the coarse, short metric threads dont instill much confidence. your dimensions are like mine btw. On another note, are you going to offer a thread protector for the break? Any suggestions on refinishing the barrel where AI machined it for the factory break clamp?

Re: Thunder Beast Arms - New Brake-Attach Suppressors

We don't have any ready right now. The way the shoulder is set up it's very hard to hit the threads. I'll see if we can make a batch.

For refinishing, it kind of depends how serious you want to do it. Cerakote would be best, but it's pretty inconvenient to apply.

Re: Thunder Beast Arms - New Brake-Attach Suppressors

at this time, they do not come with thread pro. as Zak mentioned, the threads for the suppressor are rearward of the muzzle and are out of the way so to speak.

Re: Thunder Beast Arms - New Brake-Attach Suppressors

I found out from my IT guy, that it is a product of the Barracuda here at work. I will check everything out when I get home.

Question: About the muzzle device, what are the recoil properties like without the can?? Is there any reduction??

This question may be easily understood when I can get to the website. Again, I will check everything when I get home.

Thanks!!

Naturally. They're good muzzle brakes.

Re: Thunder Beast Arms - New Brake-Attach Suppressors

Good to hear. So do you handle the gunsmithing of the barrel and application of the attachment??

What kind of warranty does the can carry??

What kind of turnaround time on the barrel with brake??

Sorry to be asking so many questions... but I am definately in the market!!

Re: Thunder Beast Arms - New Brake-Attach Suppressors

I am mostly concerned about the recoil and my wife's shooting. My 10PC being 20" kinda beats her up, and I am going to try and get her out hunting with it as well. So to just have the muzzle brake only, I was hoping the reduction was significant.

Thanks in advance for any and all information!!

Re: Thunder Beast Arms - New Brake-Attach Suppressors

The web site has most of the info you ask about, specifically warranty.

The brake includes installation instructions. A gunsmith is not required. You do need to check suppressor bore alignment once initially installed on the rifle - just like any suppressor - and we include instructions for that with the suppressor.

The recoil reduction of the 30BA brake (alone, without suppressor) for .308 will be about the same as the other good brakes on the market that are roughly the same size. A big Badger brake might be more effective but that wouldn't fit inside the suppressor. On the other hand, the .308 doesn't really have enough gas to make a big brake work much better than a small brake.

Wow... that is interesting. I will definately be checking out the website tonight!!

I do appreciate your patience with the questions. Looks like I may be a customer after going over the website... Thanks again!!

Excellent. My SOT is placing an order for a few cans and I had him make an order for me for a 30BA.

Re: Thunder Beast Arms - New Brake-Attach Suppressors

Sorry, yes. No gunsmith required if you already have a threaded muzzle with in-spec class 3 threads. We include a peel washer with instructions how to "time" the brake.

If you need your barrel threaded, we can do it, but it's usually more convenient and cheaper to find someone locally who can put class 3 threads on your muzzle.

Re: Thunder Beast Arms - New Brake-Attach Suppressors

Zak, can you tell me what the coating is on the break? Im going to time my break on a lathe and I'll need to refinish it

Re: Thunder Beast Arms - New Brake-Attach Suppressors

It's an ANSI/ASME specification for thread fit

http://en.wikipedia.org/wiki/Unified_Thread_Standard

<div class="ubbcode-block"><div class="ubbcode-header">Quote:</div><div class="ubbcode-body">
Tolerance classes

A classification system exists for ease of manufacture and interchangeability of fabricated threaded items. Most (but certainly not all) threaded items are made to a classification standard called the Unified Screw Thread Standard Series. This system is analogous to the fits used with assembled parts.

Classes 1A, 2A, 3A apply to external threads; Classes 1B, 2B, 3B apply to internal threads.

Class 1 threads are loosely fitting threads intended for ease of assembly or use in a dirty environment.

Class 2 threads are the most common. They are designed to maximize strength considering typical machine shop capability and machine practice.

Class 3 threads are used for closer tolerances.

Thread class refers to the acceptable range of pitch diameter for any given thread. The pitch diameter is indicated as Dp in the figure shown above. There are several methods that are used to measure the pitch diameter. The most common method used in production is by way of a Go/no go gauge.</div></div>

Your machinist will have a full set of thread specifications.

Excellent job on the BA concept that does not need a smith for installation. I have several 338s currently threaded at 3/4 x 28. AM I reading correctly that your BA will thread onto my exiting threads?

Obviously the can threads onto the BA, so that part is a no brainer.

I placed my order for the 30BA yesterday thru my local SOT. He ordered other models as well I believe. Will be my 4th TBAC can.

Yes, the brake should screw right on. With threads, there is always the caveat that the threads need to be cut to spec, the shoulder square, and everything true to the bore. In that regard, it's no different than mounting a direct thread attach suppressor. We make brakes in 6 of the most common thread patterns for .338's, 3/4-28 included.

Re: Thunder Beast Arms - New Brake-Attach Suppressors

A nice clean job, well done! No need for ratchets at all, never was!

Same concept from AWC/DTA (Desert Tactical Arms)for the PSR trials a number of years ago. This design was originally done by Chris Short from AWC and worked perfectly. Easy to clean, easy on and off. They ended up with a different thread pitch, but yours looks pretty identical to me. If the concept is accuracy, its the way to go.

Please don't perpetuate the misleading industry practice of not including the weight of the brake with the suppressor. That design was a nice straightforward design, keeps the weight low and should be added into any sales materials.

Re: Thunder Beast Arms - New Brake-Attach Suppressors

Zak,

Question on the BA option. I haven't had my Thruster brake off yet, but know for sure it's at 5/8x24. Now, I notice on your site there needs to be .600 of frome outside thread to shoulder. Doing a little research, and help from Willie, BO specs for the thruster is .500 (http://badgerordnance.com/wp-content/plugins/downloads-manager/upload/306-30B%20Thruster.pdf).

Is this enough for the brake on the 308BA?

Re: Thunder Beast Arms - New Brake-Attach Suppressors

The "suppressor over brake" idea has been around for a long time; the details in the different incarnations are often what make the whole system work well or poorly. The 338BA has the same performance that everyone loves on the 338P-1.
