I've got plenty of them in several different cartridges. I guess you've never heard of an adjustable gas block. I run Superlative Arms gas blocks on all of mine, and shoot suppressed 100% of the time. No over gassed issues here!

Colt made and supplied a hydraulic buffer with their LMG upper kit … I bought one of the Colt LMG conversation kit years ago as a collector piece (it’s still NIB) when I saw it advertised in SGN for $699 (iirc) and was very impressed with the buffer concept.
The other hydraulic buffers I see on the market seem to have tiny pistons and never bothered with them but a few years ago I came across the Colt hydraulic buffers on GunBroker I bought 3 and put one in my M16, one in my 308 AR10 and one in my 6.5 Creedmoor and to didn’t make much of a difference in any of them … I was hoping for a dramatic recoil reduction like I got in my HK91 when I put a HK21(308 machine gun) buffer in the 91.
I haven’t invested much in recoil reduction for the AR15 or AR10 because there just isn’t much recoil to begin with.
I did put a JP captured recoil buffer and adjustable gas block in my AR Service Rifle that I used to compete with and it made a bigger difference in controlling muzzle rise than the hydraulic buffers.
Below is the Colt LMG system.

The problem with the other hydraulic buffers is you get what you get, can't fine tune the system.
Also the hydraulic shock mod is about 1/10 the price of a nice, adjustable gas block.
Add tungsten weighs to your hydraulic shock, still less than half the price of a nice adjustable gas block.
Ideally with an adjustable gas block I would run a standard or H carbine buffer, the hydraulic shock and that be it.
I was looking for a specific gas block and they just came back in stock. I wasn't going to pay 2x or 3x the price on gunbroker just to get one a little sooner.

I’m still convinced this “solution” is much like wearing a helmet because beating your head against a wall gives you a headache.

Silent buffer with out the silent buffer price.
Most people don't think that the slamming screen door sound the buffer makes is a problem.

Just by looking at it I can already tell it sucks.
The further deviation from stoners design, usually guarantees the worse it's going to be.

Rifle buffer speed.
It says 16 inch barrel vs a 20 inch.
I'm assuming that means a disapator vs an A2.

I can see a small problem with your set-up.
You have a small diameter rod hitting the plastic buffer bumper. That's not going to last that long.

Then why can I observe that happening thousands of times per day in an industrial setting for months at a time and they don't break?
Assume it was a problem, then simply use a buffer that doesn't have a plastic tip.....
(As shown on the 12mm shock in post #2)

Does your industrial application have that small diameter rod in the hydraulic thing hitting a (relatively) soft plastic bumper at approximately 10 to 15 fps? You'll probably get better life with an increase in contact area

I don't get it, this isn't something new I know Kynshot has been around for some time now. The Kynshot looks refined with a impact area that will preserve the buffer weight rubber/polymer and comes with manufacturer backing.
https://www.kynshot.com/products/our-products/kynshot-rb5000-9/
Is this to just satisfy doing it oneself? Or to save a bit of money?
The Kynshot linked above sells for $100, I guess they have different options:
1. Standard 5.56
2. Subsonic 300BLK
3. Heavy thumpers 450bm, 458Socom, and 50Beowulf
4. PCC's

It probably works great. It's $130 doesn't appear to be adjustable or tunable. So if you buy it and you don't like it, your gun doesn't like it or it doesn't live up to expectations you're out $130, plus sales tax plus shipping.
It sounds exactly like what my setup does, "significantly reducing felt recoil".
Except my setup is $20 plus you will need a longer tube or shorter buffer. It works with the existing flexibility of the nearly infinite combinations of all the buffers and buffer accessories already out there.
If you want to run an 11oz solid steel rifle buffer you can do that. If you are trying to go for ultra light weight and are running a sub-3oz buffer that will work too.

Already checked the specs did the math.
Velocity is irrelevant.
Industrial shocks like this are rated in KE.
For example the smaller ones like I use are rated for around 100ft.lb of impact force.
If I had a 11oz BCG plus an 11oz solid steel rifle buffer hitting the shock at 20fps that's only like 9 foot pounds....
Same 11oz BCG plus a normal 5oz buffer traveling at the normal operating speed of 11fps less than 2ft.lb.
So ya I think it will handle it.

Sorry posted the wrong link, most of the time I see it for $100, but there are cases where one can find it quite a bit cheaper.
$65

I've never tried one but have thought about it when one sees a price like above, but I've never thought the recoil warranted it, and an adjustable gas block, and a gas busting charging handle, solves much of the suppression issues.

I never used a special charging handle.
But I also don't use over baffled silencers extra quiet silencers that should probably only be used on bolt action guns on my semi auto.
If I was poor and was only going to spend $70 to $100 on a buffer upgrade and I could choice between a heavy buffer and the kyn buffer. I would go with a heavy buffer.

OP, sorry if I missed it, but did you ever post a price for the 10 mm shock absorber and a source link?
And kudos to anyone who tries something different, I've had many failures & sucesses with playing around with parts lying around.
I usually just use some tungsten weights and a few Sprinco springs in different weights to dial my builds in. That's fine for me.
What a boring world it would be if we all just stuck to off the shelf solutions.

While the AR is the lightest recoiling center fire long gun I have … what have you done lately?
Personally I’d like to see something other than a muzzle device to control muzzle rise, so far the only thing I’ve found is adding weight or a suppressor. The SiG 55X rifle has almost zero muzzle rise without extra weight or a suppressor.

New shooters, women, faster on target follow up shots with heavy ammo and maybe someday if I'm lucky or rich use it to tame full auto. As I found dot gov M4 carbines rather unpleasant and less controllable than I thought they would be on burst.
I have an elderly friend who can't shoot his 308s any more because his shoulder is all eaten up by arthritis from winning rifle matches in the 80s and 90s, I say every little bit of recoil mitigation helps.

I would change them out at work on industrial automation stuff at work. Sometimes an extra one followed me home so I got plenty. If I had to buy them I would probably try ebay and search business industrial for "10mm SMC shock absorber" or "strut" in place of "shock absorber". Last time I checked a new SMC 10mm shock was around $25.

I find the haters have spent a lot of money on something else that doesn't work at all or doesn't work nearly as well as advertised.

Maybe so. I have used an M-16 on full auto. I did not have a problem with it. I was trained to use it in short bursts. My comment wasn't meant to be serious. Bad joke I guess.
