Hi,i have a Ruger 10-22 that i want to put a sling on and need the best way to put sling a sling stud in the buttstock.the butstock is a factory Ruger synthetic and is hollow.There APPEARS to be no way to enter the rear of the stock to do something like put a wodden dowel into the stock to give the stud something to screw into..I have had a few people tell me that I can just take a regular stud which is intended to screw into a wooden stock and screw that into the stock with or without epoxy on the threads and it would work fine but for the life of me I just cant see that being a very sturdy setup.I can see the screw either cracking the stock and pulling through or just pulling through .I would appreciate information from those experienced in this particular setup.Thanks,Craig
