I was given a couple of 5/20 HK91 mags recently. They have a wooden block epoxied to the floor plate as a filler. Probably not the best method I could think of.
Can anyone tell me the proper distance down to drill and place a rivet? Should a rivet be placed on the spine like an AR mag, or is there a better method for HK mags?
Please help!
