EJ, I have a number of GNR Encores

with Burris and Leupold scopes on them. I have several other Encores with Nikon and Simmons on them. Some have muzzle brakes and others don't. I have not had a scope blow up on any of them (yet). The firing impulse acting on the lever arm direction from the point of ignition (the bullet coming out of the case) to the scope determines the energy (along with the weight of the scope and gun acting against each other) that is imparted to the scope. Well made scopes have internals that are designed within parameters of impulses from most calibers in a test barrel that does not have a muzzle brake on it. (This is from a Ruger Tech I talked with this past spring at Larry's here in Huntsville Alabama. We were talking scopes at the time as I was looking for one for my Marlin 1894. Basically I was told a muzzle brake would NOT make much difference as the muzzle was letting out compressed air through the holes as the bullet passed them. It does make a difference in the felt recoil but the impulse the scope feels has already occurred by the time the bullet gets to the muzzle.
