Can't make up my mind I have a suppressed 223 with adjustable gas block looking to take away as much recoil as possible to see the flying acrobatics of the gopher hits. I have a little spring noise now but it's not bad & at times it does fail to strip a few rounds if I'm on good varmint ground. I have read allot of reviews but few talk about the Hydraulic. Thanks
 
I have not used the Hydraulic much but do have a couple on hand from past use. I have the JP SCBS in all my AR's that I shoot. I do really like them. Really quiet the rifle down and smooth it up.
 
Try greasing your recoil spring....( not a ton, but you'll know if you try it ) and hone your buffer tube's interior. A lot of them are "rough" inside.

And I am very content with all my Tubbs Flatwire recoil springs.
 
Hydraulics are for machine guns with carrier bounce issues.

I'm not sure it would do anything positive for you.

The JP SCS does run nice and smooth, perhaps a light weight carrier to mimic the JP LMOS system would yield good results.
 
Try greasing your recoil spring.

This is as good as the expensive SCS for eliminating spring noise. I have both and side by side you can't tell the difference. I'm amazed that more people have not figured this out. A dab of bearing grease on the spring and an adjustable gas block is money well spent.
 
I've noticed recently a couple other captured spring systems on the market besides JP. Armaspec makes two different types, have any of you guys tried them?

Here is one: https://armaspec.com/product/stealth-recoil-spring/
I've run the Stealth version back-to-back with the JP in a blowback 9mm. The Stealth is slightly softer recoiling with its double recoil springs giving it 2-stage dampening. Their Sound Mitigation model is closer to the JP in operation.
As for hydraulic buffers, had one in a 5.56 SBR way back when. Very soft shooting but also a lot harder to lock back the bolt with the charging handle (because you had to cycle the hydraulic piston at the very end of the rearward stroke). There's also the possibilty that the piston will start to leak as the seals wear.
