I finally acquired a 110 BA in 338 Lapua Magnum. First thing was to remove the rail to mount a new mount. The forward three screws came out easy. The last one the torx bit broke. I have tried to pick it out but no luck. What should I do next? I'm pretty mechanically inclined and do most of my work myself. If drilling it and extracting is next what kind or brand of drill bit should I get? I think a really good drill bit or set would be the most important thing. Taking it to a gunsmith where I live is out of the question. Really rural area. Just a little info if anybody could help?
