-AAC 762-SD
-AAC 762-SDN-6
-AAC Cyclone
-AAC Cyclone-K
-Gemtech HVT (thread-on)

-YHM Phantom 7.62 SS/QD
-YHM Phantom 7.62 Ti/QD
-SWR Trident-9, 9mm suppressor

ABOUT THIS TESTING SESSION:

All of the suppressors cycled our Noveske perfectly, with the exception of the Gemtech HVT. For some reason the Noveske and the HVT didn't get along - we had feeding issues three times during the 10 round test.

We included one 9mm suppressor in this test. Most manufacturers rate their 9mm cans for 300 Blackout / 300 Whisper subsonic ammo. We'll do a full "9mm suppressors on 300 Blackout host" test in the future - we included this one 9mm can in the test for comparison purposes only.

That the SDN6 is over 5dB LOUDER than the 7.62-SD pretty much contradicts everything that has been said about which to put on a short BBL.

I also see it is only 92 degrees, must feel like winter compared to previous tests.

ETA:

So the Sandstorm performed based on 300 BLK 8 inch. Doubt many would have bet on that.

LOL - I almost went inside to get a jacket to put on.

I was hoping the N6 would OWN on the SBR 300 BLK.

But keep in mind, it has had very respectable results on 5.56mm & 7.62mm.

Wow the SDN6 is pretty disappointing.

Thanks for the test. I'm disappointed in the SDN6 too.

Could you do a 300 Blackout test with 9mm cans?

[MAJ MALFUNCTION]

Could you do a 300 Blackout test with 9mm cans?

Yes sir!

Already planning on it!

I'm waiting for our Liberty Mystic & Infinity to arrive, before we do the same test w/9mm cans.

I'm glad I held off on the N6 for now. Compared to the standard SD it makes no sense for me I feel, same weight, louder, and only an inch shorter? Nah. Maybe it's a lot tougher being inconel but I'm not ever going to wear any of my supressors out.

No kidding, I had high hopes for this one!

[Nighthawk]

Same here. Too bad it didn't live up to the hype on shorter barrels.

Add me to the list of people who are scratching their heads at the SDN-6. I expected mid 120's to be honest. When compared to the SWR Trident it makes me wonder if one already owns a 9mm can would it be a worthwile investment to buy the N6 for subsonic only use.

Bryon, when you shot these did you hear any noticable diffence between the Trident and the N6 tone wise? Do you feel that the Octane HD (which you metered at 4db lower than the Trident in a seperate 9mm test) would equal it or is it just to soon to tell with only one test run?
