For a while, the CAT BBK has been my reigning champion for extremely quiet .300 Blackout subsonic performance. It has been an absolutely ridiculous suppressor and has become one of the standards I use when something new comes through the Silencer Analytics collection. Today, we're putting several .30-caliber suppressors against it—and the returning AAC 762-SDN-6 just did something I wasn't expecting. It beat the BBK. We're testing these suppressors on both approximately 9-inch .300 Blackout gas guns AND a sealed bolt-action system, shooting subsonic ammunition throughout the test. That distinction matters. A suppressor can behave very differently on a semi-automatic rifle than it does on a sealed bolt gun. On the gas gun, the complete shooting experience includes the behavior of the operating system, gas and ejection-port noise. Move to a sealed bolt gun and we get to hear what these suppressors can really do without the action opening during the firing cycle. The CAT BBK starts every comparison as our king-of-the-hill baseline. First up is the T&K VORIX MAX 30. On the gas guns, I still gave the advantage to the BBK. But when we moved to the sealed bolt guns, the VORIX MAX and BBK became incredibly difficult for me to distinguish. I called them essentially a tie. That's an impressive showing for the VORIX MAX and puts another serious contender into my .300 Blackout testing. Then came the AAC 762-SDN-6. This thing shocked me. On the gas gun, the SDN-6 didn't just sound good. To my ear, it beat the CAT BBK by a significant margin and had an incredibly deep tone. Then we moved to the bolt gun. Same result. The SDN-6 sounded better to me than the BBK—quieter with a deeper tone. In today's testing, the AAC 762-SDN-6 officially takes my .300 Blackout subsonic king-of-the-hill position. That's particularly interesting because I've already been impressed with the SDN-6 on 5.56 and with its relatively low back-pressure behavior in my previous testing. Usually there are compromises. A suppressor that does extremely well managing gas on a semi-automatic system doesn't necessarily become the quietest option on a sealed bolt gun. The SDN-6 is making that relationship very interesting. We also tested the Backwoods Suppressors Timberwolf Ti. The Timberwolf didn't dethrone the leaders for absolute sound performance in this particular test, but that's not necessarily what the suppressor is trying to accomplish. It's an extremely lightweight titanium .30-caliber hunting suppressor, and it produced a good tone while offering a very different weight and application proposition. We also put initial rounds through the Iron Eagle. I saw significant flash during the early testing, so rather than draw a conclusion from a brand-new suppressor, I'm going to put more rounds through it and bring it back for a fair evaluation. That's an important part of how I approach testing. If I don't believe I've given a suppressor a fair opportunity to demonstrate what it can do, I'm not going to force a conclusion just because the cameras are rolling. Today's major takeaways: The CAT BBK remains an incredible suppressor. The VORIX MAX 30 is becoming a legitimate contender and essentially tied the BBK to my ear on the sealed .300 Blackout bolt gun. But the biggest story is the AAC 762-SDN-6. On both the gas gun and sealed bolt gun in today's test, the SDN-6 took the crown from the CAT BBK for my preferred .300 Blackout subsonic sound. Now I want to push it further. 6.5 Creedmoor. .308. More 5.56. More hosts. And I really want to see what AAC has done with the return of the M4-2000 if the SDN-6 is any indication of what they're doing with these modern versions of their classic suppressors.
