I'm not having much luck finding stocks for the target action, especially a stock with no inlet and (ideally) one that accommodates that third action screw. HSPrecision has one, but it doesn't use the middle screw. What else is out there for this action? (not benchrest)

I'm looking at the Bobby Hart LRT stocks on Stockys, but I'm confused whether it's inlet or not.

If I have to go with a blind magazine style stock, is it worthwhile to try to adapt it / pillar bed it so that there is a strong mount on that center screw?

Suggestions?
