That's easy - when you coming back? <lmao>
One the 300BLK, I don't have the rear sight on there - that rifle isn't really "finished" yet. The rear sight will clear easily, though, with the size of that scope. Running irons through a scope is a PITA, unless it's a true 1x on low power. It's rough on 1.5x power. At 3x power, your frint sight isn't even visible in the lens - the scope is already focused beyond where that front sight is mounted. On some scopes, it's even less than 3x that you lose visibility of the front sight.
On anything I have that has irons and magnified optics, the optics have QD mounts. If I need the optic out of the way, I probably need it out of the way quickly and easily. I have some QD one-piece mounts, but if I'm using rings, it's only the Warne Maxima steel QD rings. <thumbsup>
EDIT - I intentionally selected that picture of the scope, in order to be a more effective enabler... :banana:
