We’re pleased to announce the availability of the MyTBAC Warranty Registration Portal. This is a special area of our website where you can make an account and register each of your TBAC suppressors with us. This will ensure you get the best warranty service and are kept up to date with any notices about your suppressors. In the future, this will also be the way to activate the warranty on your TBAC suppressor.
In this introductory period, we will pick the owner of one suppressor registered between now and December 31st, 2015 to receive a free TBAC suppressor of his or her choice! We’ll also be sending some TBAC stickers to each person who registers between now and Dec 31. After that, we will repeat the drawing every three months for suppressor owners who registered within that quarter.
To create an account and enter your TBAC suppressors, please go to

Since we’ve come out with the 6.5mm Ultra 7 and 9, several people have asked us if we offer a 6.5mm-specific CB Brake to match. The answer is no. Here’s why.
A few months ago, I had the opportunity to help Cal Zant with his comprehensive Comprehensive scientific review of precision rifle muzzle brakes. One of the specific results he found was that the difference in recoil reduction on 6.5 mm from a .30 cal to 6.5 mm cal aperture was about 1-3%:
I ran tests to see how much it mattered if a muzzle brake was caliber-specific, and those results were also surprising. I tested the effectiveness of having a caliber-specific brake on 4 very different muzzle brake designs that I had in all calibers: the APA Little B*, Holland 1.25” Radial QD Brake, Impact Precision Brake, and West Texas Ordnance Brake. I only found an improvement of 1-3% if a brake was 6mm rather than 30 caliber (7.62mm).
To be clear, I tried the 6mm, 6.5mm, and 30 caliber brakes all on the 6XC, and in all 4 muzzle brake designs, there was only a difference of 1-3% in recoil reduction in terms of both overall momentum and peak force. That surprised me. I expected the caliber size of the bullet hole in the brake to make more of a difference. But, that’s why I actually run the tests and don’t just talk about this stuff!
In our application, that 1-3% of difference in recoil reduction would only be applicable when the suppressor was not mounted. Here is a tech note that that effect.
With the suppressor mounted over the brake, the 6.5mm-specific suppressor baffle apertures capture as much gas as possible to give the additional suppression. That’s the part that makes a 6.5mm Ultra 7 about the same dB as a .30 cal Ultra 9 when shot on a .260 Rem or 6.5 Creedmoor.
Based on this, we do not offer a separate “6.5mm” CB brake at this time.
If you have any questions, please do not hesitate to give us a call or shoot us an email.
Again, you asked for it and we built it. We are happy to introduce two new additions to the ULTRA family: The 6.5 mm ULTRA 7 & 9. These are identical to their .30 cal siblings in appearance, weight, and length. The difference is that when shooting 6.5 mm cartridges (or smaller), the 6.5 mm ULTRAs will provide an additional level of sound suppression.
For example, shooting .260 Rem mag loads, the 6.5 mm ULTRA 7 has the same or more sound reduction as the normal .30 cal ULTRA 9. With the 6.5 mm ULTRA 9 on a .260, the level of suppression is approx 2-3 dB better than the .30 cal ULTRA 9. The prices will match the .30 cal ULTRA 7 and 9 prices.
Ultra production has been scaled up significantly over the last seven months to match the high level of demand. Right now we are about eight weeks out on production. We are taking 6.5 mm ULTRA orders immediately.
For those of you with .30 cal ULTRAs already on order, if we have not yet built your suppressor, it can be switched to the 6.5 mm version.
The TBAC office will be closed Wednesday July 15th from 1030 – 1430. We will return calls and emails when we get back to the office.
