| Hey guys, hope someone can help. I'm setting up my ruger similar to my m1a duty rifle. I installed tech sights. Then I installed one of the UTG rails and a handgun scope in the scout position. My problem is I can't secure the end of the rail because the rear tech sight is using the scope ring holes. I'm looking to drill and tap a second set of holes in the middle to back third of the reciever to secure the back of the rail. Does anyone know what the thread pitch is on the factory scope ring holes? Thanks for the help. |

If no one here knows, the guys on RFC do. I remember the question being asked over there... http://rimfirecentral.com/ |
