The way I got around this issue of only using the crappy swivels on the Vepr Super 223 that I own is to mount Uncle Mike's Quick Detachable Bases #2520-0 with the 1/2" and 3/4" long wood screw studs and leave the forestock with the 5mm 60 thd/in screw as is. It is needed to secure the end of the barrel to the stock. No, I chose not to retap it even though a 10/32 UNF screw might just work. The metal is very thin on the sides and I didn't want to risk fracturing this stub in the process. On the back end of the stock I went to www.woodcraft.com and purchased some 3/8" dia Walnut wood plugs, (part no. 17P11) and epoxied it in place using System Three T-88 Epoxy also purchased at Woodcraft.com. Be sure to tamp the epoxy down into the existing screw hole and then cover the sides of the plug and upper sides of the hole with epoxy also where it will bond to. It takes overnight for this epoxy to cure but I gave it 2 days so there would be no problems when I redrilled it with Uncle Mike's Swivel Installation Step Drill Set #2552-0. Be sure to use the smaller diameter step drill for drilling the root diameter of the 1/2" dia swivel stud which I used on the foregrip . Measure with a vernier calipers (buy at Lowe's Home Improvement) to be sure. The 1/2" long swivel stud
will work on the forestock without any modifications to the stud ie. shortening it as it will not come in contact with the barrel when installed in the stock. The only problem I really encountered in this is that I could not reinstall my trigger safety after I removed it inorder to remove the entire receiver/barrel assembly from the stock. So I just put some black plastic plugs for 1/4" dia holes in them. Who needs a safety anyway, if the gun is always loaded and handled accordingly. A safety is a false sense of security. One last thing, be sure to put some liquid dish washing soap on the stud threads when you install them. It lubricates the threads and makes the swivel much easier to twist into the stock. The distance I used was 2" from the opening in the stock for the factory front swivel to the new location of the new swivel. The most critical time
in installing swivel studs is at the very beginning. Concentrate on keeping the center axis of the stud inline with the centerline axis of the hole and turn it very slowly
while applying medium downward pressure. Use a pin punch or small screwdriver thru the stud swivel hole to help apply the torque needed to get it to begin to thread in. Ex-
ercise patience and don't get in a hurry. In the end, you will have swivels studs that will like like they were put in at the factory.
