Materials and specs
Molded of the same high-quality material as other Magpul polymer accessories,
All hardware necessary for attachment directly to M-LOK slots on compatible aluminum or polymer hand guards and forends in included: Two screws and two T-nuts. You will need a 1/8" hex key to tighten the screws.
Overall length: 100 mm / 3.95".
Weight: 34 g / 1.2 oz
Can you fit this to anything else?
To mount this on legacy MOE slots, the easy and reversible way is to usethe 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.
