I've got a new rifle built off the Lawton 7000 action. It requires 2 front Rem 700 scope bases. However, the receiver is drilled and tapped for 8-40 screws. Lawton sent me a set of 8-40 screws but they have a large taperd head that is probably for their 20moa base. The head of these screws will not fit in the head recess of the Burris bases. Does anyone know where I can get a set of 8-40 screws that will fit?
