I really don't think there is one universal tool for securing an AK ...the old mag works great for some light duty jobs if you remember the gun was designed to hold the mag not the other way around. I have seen gun vices at LGS and they seem to work,some jobs i secure the front and rear of a gun with 2 vices [one vice is bench mounted] . Other jobs wood chocks to level it sitting on machinist blocks so i can drive a pin, i have spent 20 minutes or so securing/supporting a gun to drive a pin out in 30 seconds.
