Brownells makes a kit with "1/2" hard pins for this type of repair. I've used them on several guns and found they work very well. Drill with the supplied drill apply accraglas or some other epoxy, screw in and file off the excess.I did drill all the way through on the ones I repaired, these were not high end guns and the small tip showing was not an issue. They do file off flush very easily. Here is the part number 080-565-000WB Stock Repair Pin Kit.
