I bought a new moss 500 woodstock shotgun and it didn't have swivel studs already in it. I called them and they sent me the magazine tube swivel stud and a wood screw buttstock swivel stud. My problem is with installing the wood screw swivel stud into my buttstock. Do I need to pre-drill a hole or something, I don't know! If so, how deep a hole? Like I said, they sent me a wood screw swivel stud but I don't know how to install it into my moss 500 wood buttstock. This is my first gun.
Measure the length of the screw and its diameter. Select a drill bit a few hundredths or even a tenth narrower than the screw. Use something sharp - I suggest a centering punch - to make an indent to take the point of the drill bit and drill a pilot hole the depth of the screw into the stock. Then carefully screw the swivel stud into the hole. It's not difficult.
it should be pre drilled, and a countersink made in the hole for the head of the swivel (they actually sell a special tool for this). take it to a gunsmith, its way too easy to f up, even though it appears to be a simple job.

You're right, it's so easy a job that you can screw it up. BUT, if you do plan on doing it yourself, also remember that the hole must be drilled 90 degrees to the buttstock wood.If it's off to either side, you're gonna see it and feel it. Take it to a gunsmith; he'll have a jig to put that hole in it's right spot.
If you decide to do it youself here is a chart that will help you determine the correct drill size for the pilot hole. I don't know off hand what the screw/thread size is for your Mossberg but if you took it with you to Lowes or Home Depot they will be able to determine the size for you and then supply the correct drill size. After you have the correct bit you can mark the correct depth on the bit with a sharpie or tape so you will not drill to deeply. Center punch your location and keep your drill perpendicular to the stock. Regular bar soap like Ivory ( or what every you have ) rubbed on the threads of the screw makes a great lubricant when screwing any kind of screw into wood.
Because of the slope of the buttstock surface at the sling swivel spot with respect to the grain of the wood, a surface chip is very likely upon drilling and/or when screwing in the swing swivel stud. So; select your spot and put a 3" long piece of heavy 2" wide masking tape over that spot. Then do the center punch firmly into the wood and thru the masking tape. If you have a Vernier Caliper it is easy to get the minor diameter reading on that sling swivel stud. I always selected a twist drill .010 to .015" smaller that that reading. Drill down a little deeper than the length of the stud. I too used just a little (very little) bar soap on the stud to ease its path down into the drilled hole. Particular attention needs to be paid to keeping the stud aligned with its drilled hole while screwing it in to prevent that ugly stock chip. Just before the stud head is seated on the stock tear the masking tape off and wipe away any sticky residue. Finish seating the sling swivel stud and you are done. ..... Big Cholla
I bought a kit like that for my 870 about a year ago. It gave me instructions on what size bit to use. I just "eyeball measured" the stud threads beside the bit and did the old masking tape trick. Everything went smooth from there. I see no need to take it to a smith, but if yours didn't come with a drill bit size to drill the pilot hole(which it should have), then just start off smaller rather than larger. Dont wanna make it too big and have the stud fall out because there's not enough wood for it to get ahold of.
Thanks to everyone for getting back. this forum kicks ass. I thought about doing it myself but since this is my first and only gun, I really didn't want to f it up on something little. This is my 1st gun and I already spoil the lil guy so I took it to my local gun shop and they did the job for about 15 bucks flat. They also answered some questions I had about cleaning my gun. I'm already planning on buying a used 20.g pump for my old man so I'll try my luck at installing those studs myself. Now I know what to do. Thanks.
