Anyne have experience with JP Capture Spring?

[OKCShooter]

I have a suppressed AR and thought this might help knock down that annoying spring sound and shoot "Smoother"?

Is it worth owning or just another answer to an unnecessary question? I currently run an H2 buffer...

it will quiet the "spriong"; its a nice piece of equipment. A little heavier component wise than stock, but I dont mean that the cycling buffer part is, necessarily.
Not heard about use with suppressed rifles, Ill ask a buddy in the know tomorrow if he doesnt post here before then.
Theyre pretty popular, Ill bet you could sell it in a heartbeat if you dont like it.
