This is a standardized Keymod reference guide. This reference has all the dimensions necessary to machine standard Keymod adaptor. This reference only has 3 keymod holes but you can use the dimensions and add as many as you want. This diagram follow the actual standardized method used by Knights Armament, Noveske, LWRC, Magpul, Troy, ADCOR, Barrett, SIG, FNH, Seekins, PWS, AAC and Colt. This reference has the dimensions for the thickness of the material you wish to machine Keymod holes, along with the dimensions for the keymod itself for both sides including radius, chamfer and alignment/indexing grove. I left drawings highlighted to show that there are 2 sides that to a Keymod hole.
