I just redid the pin and weld on my SCAR 16S NRCH 14” to run the extended length HUXWRX flash hider. I put on the Flow 556k, and the recoil was harder than usual. I put the gas block switch to the suppressed setting, and I had no issues 200 rounds of shooting. I got 4 o’clock ejection, brass flew maybe 5 feet or so.

I maybe have 1000 rounds or so on the can. Maybe I need to go ahead and clean it. I thought I could go 2500 rounds but maybe not. Thoughts?

I am also going to try the Flow 762 Ti the next time I go out. People tell me it works better on 5.56 guns than even the Flow 556k due to the larger volume.

I've had the OSS BRP SRM6 one on my 17 since late 2014.
It's great.

I run the KNS discarder and a 5.56K.  The recoil is noticeably sharper without that can.  Not that it's bad, but its' so stupid mild with that can on.  Same story with an XCR.  The Scar does run a little dirty even with the low pressure can, but it's not terrible.  Ejection is around 4:00, IIRC.

I clean it with the Breakthrough solution once every so often....no problems yet.

See, mine recoils more with the can. I guess I need to clean it even though it has less than 1000 rounds through it. Again, this is a Flow 556k.

Won't hurt to clean it and find out.  Report back for a nice datapoint.

I always felt like mine reduced the recoil impulse.
Maybe it was just me? But when it was clean and newish it did a much better job.
Just got it back from a full clean and detail. I put it away very dirty 5 years ago and couldn't even get the two halves to attach.
Highly recommend more frequent cleanings and removing the mount as well.

Softest shooting 5.56 I own.

Hux Ti, 11.25" barrel chop by PMM years ago, have no idea what jet they installed but its epic.

I cleaned the Flow 556k can with HUXWRX's suppressor sauce cleaning kit. Now, little back pressure on the non-suppressed gas setting. It just barely cycles on the suppressed gas setting.

I typically use good quality factory 5.56 ammo. It's not like I was feeding it steel cased. What upsets me is I probably had < 1000 rounds through it over a year. I guess that was enough, given the long time frame, to gunk things up. It sucks though knowing I'll have to buy a HUXWRC suppressor sauce cleaning kit every 1000-2000 rounds for this Flow 556k can. I have more rounds through the other pictures 762 Flow Ti can, and it still looks good as new. I guess I'll clean it this winter for good measure, but I have not noticed any performance issues. Maybe due to the higher volume of the suppressor?

The suppressor sauce by HUXWRX works as advertised. I dunked the suppressor for 1 hour in the "Part A" solution, then 2 hours in "Part B". Voila, clean as a whistle. There is enough powder stuff and Activator "A" left over to use on a second suppressor. Only downside is you are still using chemicals. I wore purple nitrile gloves and did this in my garage.
