Gas block with an off setting?

[McSnipsy291]

Are there any companies making adjustable gas blocks with an on/off toggle of some sort. It would be nice to be able to shut off the gas without losing my standard setting and messing with set screws... maybe something with the standard setup plus an extra hole drilled straight down through the top with a detented screw in there that has a hole bored through for the gas to pass through when aligned but be completely blocked when turned 90 degrees. It would be nice to just shut my ar10 off entirely to keep quiet sometimes since it wont cycle subs anyway.

Noveski Switch block. Has 3 settings. Off/suppressed/unsuppressed. Otherwise not adjustable. I am working on plugging and re boring to off/hot weather suppressed /cold suppressed.

Awesome that looks worth a try for sure! Thanks

Noveske switchblock. Most adjustable gas blocks don't have a true "off" per say but you can close them up to the point where the carrier doesn't even move hardly.

SLR Sentry series gas blocks have a front mounted adjusting screw that has positive detent "clicks". So, it's easy to fully close it off, then return to your standard/preferred setting simply by counting "clicks".

Only bitch about the SLR and turning gas off all way, is that after playing for extended periods closed, it will Carbon and make hard to turn up the gas again with that little hex key . I have had that happen .
it a great gasblock and I love them . But after shooting closed , You need to click up again (for peace of mind) to make sure it stay's free moving ,
