Can you fit this to anything else?

To mount this on legacy MOE slots, the easy and reversible way is to use the M-LOK to MOE adapter kit.

If you have a clean slate (a reasonably flat section that matches the length of the grip), chances are you can make this work.

You'll need four 7 x 12 mm rectangular holes for the recoil mitigation lugs and M-LOK T-nuts, or just two if you make them 7 x 32 mm. The material thickness must be at least 2 mm for the nuts to grab before bottoming out.

The center-spacing of the holes is 20 mm if you make four of them.

If these measurements boggle your mind, it might be easier to just buy a metric caliper instead of converting these. For example, 7 mm is more than 1/4" but less than 9/32". It's a headache.

This should help you get started. If you're confused, choose something else to do while you drink beer. These aren't jobs for amateurs.
