I bought the Uncle Mike's swivel studs to mount a sling on my Remington 870 shotgun. I as going to modify my magizine cap to accept the stud but I lost my instructions that tell me the tap size.
Does anyone know the tap size I need to accept the screw?

If You've got a hardware store close just take it there and size it up. Could be a 8-32 or10-24 threads who knows, hopefully not a funky metric size. Once you find out what the thread size is then you can figure out what tap you need.

If you feel that you must drill a hole in the cap then you drill it slightly larger than the unthreaded part of the shaft and use the supplied nut on the inside of the cap with some loc-tite and a center punch to keep the nut from unscrewing from theswivel stud.

So no one has made this modification before? I know it was in the instructions that came with the swivel, but I lost the dang thing.
Yes, I've done a number of these. LIke I said you have to determine the correct thread size of your stud, use the right drill bit to drill your hole, then use the tap to cut the threads. I've found it easy if I have a unknown size of bolt/thread size to go to the hardware store and match it up. There is so much stuff coning out in metric sizes it's hard to tell sometimes. Then I know for sure of the size of the drill and tap I need. It's not rocket science......Good Luck

If this is the set you have. Which is the generic for "most pump and auto" according to uncle mikes website. It IS a #3 drill bit and it IS a 1/4-28 thread tap!!!
