I run my Aug M2 16" suppressed. I finally got the KNS adjuster, and here is a short discussion.

Polonium K- setting 2 on low locks back the bolt with 69gr PPU match. Setting 1 on low for IMI m193.
B&T Print 5.56-Setting 5 on low with 69gr PPU Match, same with IMI m193.
I still have a form 1 can to test, but it flows better that the polonium K on other guns. Polonium K is much more quiet though.

All said, it does what it says. Harshness is way less, and gas seems reduced. First match is Apr 4th, so we will see.

Anyone else have feedback?

I have a KNS on my 14" P&W and 20". With 5.56 spec stuff, and a Huxwrx 556k. Floats along the bottom end of high flow setting and on the top of the low flow setting. There is some overlap judging by ejection patterns. Opted for the high setting So I can bump it up if I run lower powered 223 stuff, and for 5.56 position 0 works but opted for 1, and is very smooth.

You think the adjustment tool they sell is necessary or is it fairly easy to adjust by hand?

I have no issue adjusting it by hand
