very cool,i how that could be better then a spring setiup!

This is cool but what’s inside of the barrel? I’m not getting it. I’d love to try and make one…
All I can say is wow. And I seen the tattoo u did with it smooth

thanks!

the damper is similar to this one but the spring is not inside the piston

THAT STealth dampener is neat-o
