Yes, here we go another self serving gun nut trying to make a gizmo's! I want to make something everyday guys can put on our rifles and help improve its accuracy. What have you tried and what results did you get? How was it attached? Heavy - light - ????????? Help me out here! I got a friend who owns a machine shop and I just retired. If I don't figure out a good project to do - there won't be any squirrels within walking distance. What works - what doesn't - I am cheap and no way will I spend $300-2000.00 on some custom barrel job.
