Optics: A Bausch & Lomb Tactical 10×40 scope, or sometimes Leupold MK4 10x scopes.
OP is asking about the mount. If I'm not mistaken, they use a Springfield mount. I've also seen some documentation somewhere online mentioning Brookfield. Since Springfield Armory is where the M14/M21 came from (correct me if I'm wrong), I suppose Springfield is a fair guess.
