I tried the tie wire method to secure the mag release spring and it works quite well. After looking at pics of the Soviet made tool, I decided to try and make one. I had an inexpensive 8" slip joint pliers lying around so I decided to use it. Slip joint pliers really aren't as useful as a good pair of vice grips any way. I made the prototype with a 4" grinder and a dremel. It is crude but it works like a champ. I hope the photo comes out ok.
