Do you know the width between the rails on the scorpion stock? I'm thinking that they may fit perfectly on my M11/9 subgun after I machine up an adapter.
Width of my M11/9 is 1.30".

Thanks!

Wdith between the inside of the rails is 2.00" as I recall.

Be aware, however, that the left strut sits further out than the right arm (if looking down the centerline of the buttplate) to let it clear the sling point molded on the rear left side of the Scorpion EVO receiver.

To be honest, I wouldn't be opposed to developing and running a batch of slider stocks specifically for the M11/9 and other similar guns if there would be a market for the slider stock.  I would just need some info and dimensions on how stocks are typically attached to the M11/9.
