| Need to drill a hole in my Model1 24" varmint upper for a sling stud so I can attach my Harris bipod. How would you go about doing this? Thanks... |
Don't tap the tube if you will be putting the rifle to any real use, especially if you are going to put a bipod on that stud. A stud screwed into an aluminum tube WILL eventually pull out and it will be at the wrong moment. Happened to me in the middle of a match... Now when I do these, I drill a clearance hole and use a longer stud. I have a reverse spotface tool that cuts a nice little flat pad on the inside of the tube. Here I place a stel hex nut and loctite the stud into it. These never pull out.

There is a company that sells an insert, but I dont recall who the hell it is... you could always make one, get an inch of 1.75 OD thick wall tubing and slice it up in a half dozen pieces, drill and tap the hole in the center and you have a strong backing plate/nut comination... and you can sell the other five on the EE! But as Randall says, don't just trust the aluminum tube hold it. |
+1 stud and nut would be the best option. this is what i was talking about in my previous post, the #5  basically a stud and oversized elongated nut. |
