I have a flattop upper with four rail handguard. Handguard is free float. The top rail of the receiver and the top rail of the handguard match up perfectly. I have a 1.5 - 4.5 x 32 scope with long eye relief.
Is it OK to place the forward scope mount onto the handguard rail and leave the rear scope mount on the receiver rail? So far there has been no scope movement and all seems solid. This would be for 3-gun competition.
