First time failure with Thunder Beast Arms Ultra 9 DT GEN 2 and Silencer Co accessories.

So Scheels recommended an adapter that the suppressor manufacturer doesn't recommend, and then proceeds to tell you that for liability reasons they can't install the adapter they recommend? Sounds fishy right there. The TBAC CB adapters work perfectly fine, and a TBAC direct thread suppressor is simply the suppressor with a CB mount rocksetted in it.

Was the Cooper rifle muzzle thread 5/8x24?

Sounds like a real bummer. I am curious/ confused though: what is an "adapter ring"?

Tunderbeast are the ONLY suppressors I run. Four of them. There is a reason that TBAC is the most used and winningest can on the PRS circuit.

Ultra 7 Gen 1 6.5mm
Ultra 9 Gen 1 .308
Dominus .308
Ultra 7 Gen 2 6.5mm
All using the TBAC CB

Except for the Ultra 7 Gen 2, I have thousands of rounds down three of my cans. Not a single issue. Swap them around between several rifles all the time.

You should not have mixed and matched the SilercerCo brake with the TBAC can. Not even close to the mating surfaces of TBAC CB mount. Sounds like you were trying to build the Cadillac in the Johnny Cash song "One Piece at a Time". Was your barrel threaded 1/2"×28 like the Cooper Backcountry? There is a reason TBAC only makes a .223cal version in the 1/2"×28 threads. 5/8"×24 and bigger threads are bored for both the .308 or 6.5mm cans. If your "adapter" was a 1/2"×28 to 5/8"×24, that should have been a big red flag as to why TBAC didn't make the right CB for your application. If that is not it, don't know what to tell you. All TBAC cans come with one CB of your choice if they are not the DT model. So there should have been another red flag.

Sorry, but I can see why TBAC and SilencerCo wouldn't warranty their products, there were no defects in them. Just an installation issue.

Going back and re-reading your original post, there are so many red flags with the initial installation, the info you received from Scheels and your "gunsmith", it is staggering. This sounds like a total cluster.... of misinformation.

Sorry you had to go through this tough learning curve.

I agree with lance.
He put it into better words than I could.

Bottom Line: You shot your suppressor. A bad deal, and a rookie mistake. Not the manufacturer's fault or problem.

I have a TBAC Ultra 7 and an Ultra 9 all run with the TBAC CB 30 brake. They are fantastic.

Your suppressor was likely loosening from the mount that Scheels had you jury rig and thus sagged causing the baffle strike. None of this is TBAC's fault or Silencer Central's fault. Any fault to be had is Scheel's for selling you a hodgepodge and your's for not checking the tightness of the suppressor on a regular basis at the range. You also used way to much red loctite. 2 or 3 small drops is more than sufficient.

I would suggest you go to the Scheels where you bought all this stuff and sit down with the store manage and demand a refund.

I'm sorry, but caveat emptor comes to mind! As far as I know (at least in my local Scheels), firearms-related services are limited to installing and boresighting scopes. But I trust no one to boresight and install my scopes.

Yesterday, I bought a new Chrono at Scheels. I spoke to a salesperson who said they had it, and it was their last one. I asked him to set it aside for me to pick up. No sales pitch was involved because I already knew what I wanted, as I had researched. If I made the wrong decision on my purchase, it is on me.

It's unfortunate, but I agree.

One of the main issues with using QD suppressors is that a lot of the time, there isn't a foolproof way to ensure that the suppressor is fully seated on the muzzle device. A lot of time it may look and feel like it is, but it isn't. That is why the taper mounts have become more popular.

I have used and recommended "aftermarket" parts for suppressors on multiple occasions and have yet to have that cause an issue, as long as everything is mounted correctly. You may want to have someone verify that the threads on your barrel are concentric to the bore. A lot of time, if it done by the factory, they are not. When putting on a 2" long muzzle brake that is .2" overbore, there isn't much danger if the threads are off a bit. Hang a 9" long suppressor on the end, and that changes significantly.

As for the muzzle devices and Rocksett. You have to SOAK, them in hot water to loosen them, not just dip. The fact that your gunsmith didn't know that and used heat to get them off says a lot about him.

One more question that I have for you. Were your muzzle devices just a radial brake or flash hider, or were they muzzle brakes that required timing? If they were the latter, what did you use to make sure they were timed correctly? Crush washers or peel washers? If it was the former, there is a less than zero percent chance that the crush washer applied unequal force to the back of the muzzle device, inducing cant. Again, for a standard muzzle device, not an issue. Hang a long suppressor off of it and the chance of a baffle strike becomes much more significant.

After browsing through SilencerCo. adapters I was left wondering WTH did they give him to use?

Not being familiar with SilencerCo's line up I could have missed it but I didn't see anything that would give him both the correct thread pitch and a taper to lock up on. I'd like to see a picture of what they gave you?

I went with Area 419's TBAC mount for my CB and then the hellfire adapter which has been problem free on three different rifles.

Hard lesson learned. In my opinion you need to do your own research and not rely on sales people etc. Before you buy you should know what threads you have on your rifle, how you're going to mount it, etc. I pretty much had to get new rifles when I converted to shooting suppressed and haven't looked back. Sometimes it's just more practical to get a new gun (or a new barrel) vs gunsmithing and stacking tolerances with adapters etc.

You need to verify that your suppressor is concentric with your bore before shooting to prevent a baffle strike.

Silencerco suppressors have worked flawlessly for me over the past 6-7 years.

Just learned about the Area 419 parts, curious why you wouldn't use CB style muzzle devices on your rifles instead of using the hellfire adapter + the Area419 TBAC mount? (Correct me if I'm wrong) I believe CB brake also would eliminate the need to screw a hellfire brake back onto the adapter when you're wanting to shoot braked. I know availability for CB brakes was rough but that's loosened up since SRS started making theirs.

I think TBAC missed the boat on a good way to remove a stuck CB brake from the can. SRS also solved that, just wish they'd nitride the titanium brakes

You're buying a product from a retailer and they should have employees that know this info and are very familiar with their products. They make a profit off the sale and should be giving some expertise in return for their profit.

I think the main problem is that gun stores typically cannot afford to pay for good help. Meaning truly knowledgeable workers in their products. Firearm profit margins are much lower than most people imagine. Class 3 things like cans do have higher profit margins, but without having a high volume, smaller gun store a struggle to survive and normally have to offer lower wages to workers.

A larger store like Scheels should not be selling products they are not familiar with. They also should have had enough knowledge to give the OP enough info so this would not have happened.

Sure, the OP could have researched it all himself, but he trusted that he was getting a service in exchange for what he paid. And Scheels failed him. I do not think it is 100% their fault, but they do have some culpability for not properly educating the customer on what they sold him.

Most other businesses do not require the customer to know everything about the product they are buying before they purchase. Most people who buy automobiles cannot even change their own oil. Most people who buy computers cannot even figure out how to run a virus scan. When I bought a mountain bike, I did some research but trusted the sales guy to give me good info (I went to a higher end bike shop, not a box store). I do not see this situation any different.

You had something going on when you were shooting.

I run TBAC Ultra 7 on several different rifles, all fitted with their brake attachment.

I also have a few different Silencer Central cans, 2 mounted the same way, 1 direct thread.

I can only imagine that shooting 12 shots, with everything being normal, that the can was not tight and had started to back off for that 13th shot.

Just as an FYI, a 9" suppressor, while certainly doable, is not (IMHO) the best option for a thinner barreled hunting rifle. That's a lot of heft way out inn front of the rifle, let alone the fact that its not going to be a lot fun carrying through the woods.

Scheels is not a gun store. It is a sporting goods store that happens to sell guns. Big difference.

I consider myself fairly experienced and knowledgeable when it comes to firearms. But there are certain specialty areas I don't feel comfortable expressing advice with my limited gained information.

If I worked at Scheels, and someone asked me "what is the best yoga ball" or "what are the best tennis racket strings" or "what is the best 18 speed bike for road touring"...yeah, no clue. Let's point something out to make my sales goals.

If you go into Walmart and tell their tire department you need a set of 17" rims and 33" Mud Terrains for a 2020 Tacoma, and they sell you a set of 16.5" rims for a 1980 Ford F250, "but with these wheel adapters, and multi-thread capable lug nuts, they will work just fine. Just use JB Weld to hold the lug nuts on. And these tires will need to run tubes because they are for 17" rims, but they should stay on if you only air them up to 20psi.", are you going to buy them?

The sage advice of Ronald Reagan rings true. "TRUST BUT VERIFY."
