I just had a MB installed on my 300. The rifle currently have a PST 6-24x50 FFP on it now. I'm Picking up a NXS 5.5-22x50 tomorrow. Would you mount this optic on the rifle or would you keep the PST on it. The reason I ask is, I hear great things about Vortex's warranty and I've heard muzzle brakes are killer on scopes. This will be my first Nightforce and don't want to trash it right out of the gate.
