I will post a link as soon as I can find some one who sells them.
I got this free from a guy that told me it was the best he had ever used on a bolt action .223
this with a standard CAR spring, H2 buffer, and M16 full auto BCG, the rifle has no muzzle rise at all, I mean none. As for recoil it just like a .22lr or less.
I know it sounds like a bunch of BS but u have to try it, so it doesn't look tacticool and there aren't enough threads in the break to use a crush washer.
As for noise, I fired one round with out muffs and ouch my ears are still ringing, I only hope that ringing will go away.
This brake works so well that it makes the rifle feel fake when I fire it.
