I'm going to go with the Griffin Armament tapered hub because I already have their short, tapered flash suppressor and hub adapters. This is for the Kel-Tec KP50. It ran fine with the Recce 5K, but I'm wondering the HRT 5K AM is overkill for 5.7mm? I want a slightly shorter suppressor and while I was originally looking at the conventional or AM Explorr 224, weights are all pretty similar but the HRT is the shortest. Thought @Green0?

I'm in the process of acquiring the YMH Fat Cat, but I'm strongly considering shifting to the HRT 5K AM...it will be about the same weight and slightly shorter than the Recce 5K...

KP50 with GA Recce 5K (pulled from my another AR SBR so it can't stay on the KP50):

Tag. Literally looked this up yesterday.   5.56 cans seemed to get the nod.

I settled on my non-AM Explorr for my PS90.  I tried a couple of other 5.56 cans, but they sound about the same when using supersonic ammo, so I went more for size and weight.  I haven’t found that suppressed 5.7 sounds that great unless you use subsonic ammo.

I'm using the GSL P90 for my P90, it uses their bi-lock muzzle device. Works well and sounded better than a YHM Turbo K that I was using on it before.

This has been my experience when using 5.7 rated rimfire suppressors so I’m just now switching to a 5.56 one to see how it sounds.
If it ends up being not much difference I’m just giving up on suppressing this round.

Yeah, I'm not expecting great performance, just enough to take the edge off, which is why I kind of want to focus more on size and possibly weight (the AM cans look a little heavier). Best aspect of the diminutive 5.7mm is the needed velocity which the longer 9+ inch barrels provide; no intent to really try a go subsonics.

I'm considering putting a Huxwrx Flow 9Ti on mine with the direct thread plan-b barrel adapter. Mostly because its so short and light and I just want to cut down on the blast without making it much longer or heavier.

I went with an Echo Machine Caracal can.
Specifically designed for the 5.7 round.
Like it alot.

I have a Flow 9k Ti, I may give that a shot. I have the right sized tapered hub, so it's another option.

That's one of the few cans specifically for the 5.7. Hmmm...

I'm curious about the Gemtech Nebula as well.

interesting, but that's a loooong bitch at almost 8 inches

I'm willing to sacrifice performance a more compact can for this use...
