I agree with all the above. That said, I have a B-Square mount mentioned above that I will sell you for $25 dollar. I had it mounted on a 45lc many years ago. It held zero for three years with stout 250gr loads. I removed it and put it on a single six for about 9 years with no problems....but I still would recommend
a drill and tap mount....;)
