Product Highlights Leupold' s goal of a scope that would be ideally suited to the special needs of the military and high intensity law enforcement organizations was achieved in the creation of the Mark 4 series. The Mark 4 10x40mm LR/T M1 is not only astoundingly durable, it is optically outstanding as well. The M1's oversized adjustment knobs give the user audible and tactile confirmation of each 1/4-MOA click.
