Bravo Co upper problems

I bought an 11.5" Bravo Co upper last month, attached my brand new Thunderbeast 223A, and the first shot was a baffle strike. I ended up returning the can and upper to Thunderbeast, whe sent me pics of the problem, which was the lack of an undercut directly behind the threads, which did not allow my can to line up correctly. Bravo Co is now telling me that the barrel is fine, I just didn't have a gunsmith install "shims" on my barrel that should have been provided with my suppressor, and didn't have my suppressor "timed"... How do you "time" a suppressor?

The email chain is below. Can someone please tell me what the hell they're talking about?


So what you're saying, is that the makers of all the cans I own are all unaware of the need for shims to "time" my suppressors, all failed to supply me with these shims, which all work just fine on all my other barrels, and you know more about fitting a suppressor than the guys who make a living manufacturing them. They forbid using any type of washer! The can uses the shoulder to line up! Any washer or shim screws the alignment up! *** is going on over there? How do you "time" <snip> suppressor?

There IS something wrong with the barrel, and this customer service is absolutely insulting. There's no way to actually talk to anyone there, and I have to email you morons 8 times just to get replies from someone who has no goddamn idea what they're talking about.

This email chain is going on every forum I can find.

The shims must be used and come with silencers to time the silencer. The shims in- turn also fill the gap where threads end and the shoulder of the barrel starts. Only a qualified gunsmith should install these. There is absolutely nothing wrong with the barrel.

I don't understand where the issue of shims comes in here. I never mentioned shims, and the use of washers or shims probably voids the warranty on the suppressor, they're not supposed to be used, and there should be absolutely no need for a "shim". The whole issue here is that the barrel you used on the upper I bought is not machined correctly, it doesn't allow the base of the can to contact the shoulder of the muzzle, therefore the can cannot properly align with the bore, therefore I have baffle strikes. I even sent you pictures of this.

Thank you for the info Dan, very helpful. How many shims were used to attach the suppressor? What was the width of each shim used? Please let us know.

1. It was a complete upper, new, the 11.5" with a LaRue rail, from Tilly's Armory in Burnet, Tx on 12/22/12.
2. It was not a build.
3. The exact malfunction was that I attached a brand new Thunderbeast suppressor, and the first shot ricocheted of the ground in front of me, and there was obviously a baffle strike. I returned the suppressor still attached to the place I had bought it, and they sent the suppressor and upper back to Thunderbeast. They sent me the pictures and email I am attaching.
4. It was a Bravo Co BCG and charging handle
5. Ammo was 55gr Hornady Steel Match HP
6. Pmag 30rd
7. There is a Timney trigger installed

Here is the email from Thunderbeast:

Hi Dan,
We received your upper and suppressor today. The barrel shoulder is the problem.

Specifically, the radius at the junction of the shoulder and the lack of undercut behind the threads as shown in the picture below.

With the suppressor screwed on hand tight, the rear of the suppressor does not contact the barrel shoulder as seen below.

Here is another view.

The damage to the suppressor is only cosmetic and the barrel shoulder can be trued up.

Please call me at your convenience and let me how you want to proceed.

Couple questions for you Dan.

1. You purchased a stripped barrel or an upper receiver group? From where?
2. Is this a build put together by you?
3. When you shoot, what is the exact malfunction?
4. Bolt carrier group you are using?
5. Ammo used?
6. Mags used?
7. Any accessories added to the weapon system? I.E. BAD lever, competition buffer, competition trigger?

Please let us know so that we can assist you.

I did email you, that's what you replied to. I want to speak with someone there about how the shoulder of the end of your barrel is so out of whack that it caused my suppressor to have baffle strikes. I want to know if you are going to compensate me for the cost of having your barrel trued so that attachments can be used without ruining them. I want to know how I can go buy a $1200 upper and it be such a piece of <snip>.

I purchased one of your uppers, an 11.5" model to run a Thunderbeast
223A can, and the shoulder was so out of shack I had a baffle strike.
I can't believe the lack of precision you guys send out barrels with,
and you have no phone number on your site for people to call you directly?
