For months I have been thinking of a way to make a front sling point for my ASR and finally thought up this so I can use a RIS mounted sling point. After about 3 hours of work I was able to accomplish this! The extended rail sits at almost the same height as the main rail (+ 1/2mm?). Despite this small difference, optics attach between both rails without any problems.
Materials and tools used:
Rail from the Matrix m870 pump action shotgun from evike
Hacksaw
Epoxy putty
Syringe type epoxy
Sand paper
Needle nose pliers
