PM sent to you
 

I'd like one.

Incredible work man, are these still available? I actually found this forum due to an arfcom search looking to do something like this..... this is perfect.

Yes I make them.PM me for details.

by any chance is the 3 position one adjustable for "low" gas?

The ports on this are: wide open 1/8", restriction about .082" and closed.regards.

Is there anyway to make a changeable to experiment with tuning?
(open, closed and adjustable)

You are welcomed to post details here. I would prefer that you post in the classifieds and if one sells there is a link to list an identical. There is no cost to buy or sell in the classifieds!

I am interested in these. Do you make them in .625 as well as .750?
Also what is the availability at this time?
Thanks, FH

Yes it can be made with a .625" bore.PM me.

Will your 3 position work with 223 AR like a Noveske switchblock ?
I have a Noveke with the switchblock and it works well for taming
down the strong blowback through the action when using a can
and was hoping your block would work the same way on another
AR.
