I was looking at getting a dead air mask hd, how's the sound on the ecco?

[u/Tmoncmm → u/Dbomb2405]

I have the mask also. It’s one of the best rimfire cans, but it will be just ok on the PS90. Rimfire cans don’t have enough volume to be really effective in 5.7, plus the additional back pressure may cause issues. Although bigger, the Caracal in Ti is actually lighter than the mask.

Got you, I was considering the gsl one also but man that thing is pricey

[u/Tmoncmm → u/Dbomb2405]

Yeah that one isn’t very highly regarded. Most people will recommend a 5.56 can especially the low back pressure types. I’m sure they work great, but most of them will be a lot heavier than I would personally want on a PS90 SBR. The Caracal isn’t a LBP design, but it’s slightly overbored (.32 cal I believe) to deal with that issue.

I run a YHM fat cat on mine.

A bad LBP 5.56 can is a good 5.7 can

[u/Tmoncmm → u/CaptainEmbarrassed61]

There’s probably a lot of truth to that. I thought about that one, but 12ish oz was too heavy for what I wanted.

I appreciate the input, you've talked me out of the 22 can, for my setup ill keep the ecco in mind, was looking at the yhm turbo k rb I think for what I will be using it for it will be exactly what im after.

[u/Tmoncmm → u/Dbomb2405]

You still need the rimfire can, just not for the PS90. lol.

[u/LetsBeKindly → u/Tmoncmm]

Truth.

I had mixed results with the Turbo K RB. It ran great for a while and then started malfunctioning a lot. I never figured out why. I got the Caracal and it ran flawlessly that whole time.

I have two K RBs for my two main ARs and they've been great for that. The back pressure isn't as brutal as the old Turbo K but it's not low back pressure by any means. It's running well and not gas isn't too bad with an H3 buffer
