I'd rather read the posts than write them, but I saw some posts regarding the Folding Stock for the Vepr and how it installs and thought I'd add my two cents as to how Robinson said it works.
1. The package includes a Folding Mechanism, Tubular Stock, Pistol Grip, & mounting Hardware
2. The tail on the back of the receiver needs to be cut off and filed smooth
3. There is a screw hole located inside of the top cover under the back end of the op-spring
4. The pistol grip screw will be used to hold the botom of the folding mechanism.
I hope the info helps those that were curious.
