Good afternoon everyone and thanks for coming back to TFB’s Silencer Saturday. This week we continue our dive into the Advanced Armament Corp (AAC) TI-RAID 30 and a bit of subsonic 300 blackout decibel metering. That’s 300 AAC Blackout to you. We’ve got both the direct thread and QD TI-RAID 30’s in house and they got to play on both the shortest 300BLK host I have in the armory (Sig Sauer MCX Rattler) as well as they longest (16” Remington Model Seven KUIU). If you are a suppressor owner and haven’t had the chance to dabble in some subsonic 300 blackout, I suggest you drop what you are doing and head out to the range or local gun shop to start making that happen.
In case you missed it, the unboxing, specifications and all the other basics on the AAC TI-RAID 30 were laid out two weeks ago in episode #59. In short, this suppressor is built to be disassembled by the end user, a rarity in the centerfire rifle silencer market.
This week we finally get to down to some science: decibel metering some subsonic 300 blackout. But first, my caveats:
I am not a scientist, but I do play one on the internet. Decibel meter data alone, even if done correctly, is a poor way to evaluate silencers. Your personal use case, requirements and applications are more important than any list of numbers. Decide how you are going to use your suppressor and what is important to you, then use all the factors combined to make a purchase decision. When in doubt, ask. My email can be found below.
The AAC TI-RAID 30 is a well designed and well made silencer that has a tool-less removable baffle stack. After a long cycle of shooting subsonic ammunition, simply spin off the mounting unit and push out the baffles into your favorite ultrasonic cleaner or tumbler.
Let’s get down to shooting and metering.

Conclusions:
Based on the data, the AAC TI-RAID performs really well using subsonic 300 blackout ammunition in both semiautomatic and bolt action platforms. While the Rattler cycled using the (-) gas’s setting, ejection was week. Adjusting to the (+) gas setting showed stronger ejection with no failures to feed. The decibel meter numbers appeared to increase with the additional gas, but with a small sample size, I feel that the results are somewhat anecdotal.
Both the Rattler and Remington Model 7 proved to be very quiet at the muzzle as well as the ear, sporting muzzle numbers sometimes reserved for subsonic rimfire setups. The “control” of dropping the bolt or closing the action alone really highlighted the TI-RAID 30’s performance.
While the ability to disassemble and clean your silencer is a rare feature in the suppressor world, it does come with a slight weight penalty. Whereas most current models made by other manufacturers are at 16 ounces or less, the TI-RAID clears 20 ounces without a muzzle device. Again, that extra weight may or may not be a factor in your use cases.
Aside from the weight discussion, the AAC TI-RAID 30 is an excellent performer from a well established company. MSRP is $1,119
