Standard on an Obsession. With others, you will likely pay extra. When it comes to cradling the optics, we don't mess around. All Obsessions come with a stainless steel, computer designed mirror cell. The Obsession mirror cell is mounted in an elegant 3-rung open frame tailgate which permits rapid cooling by the included fan.
Design permits primary to be left in the box during transportation and cleaning.
If the others use a solid bottom box, removable mirror or less than adequate mirror support, you will regret the difference. Our blocks are mounted on the outside of the mirror box for a compact, solid base with easy to reach knobs. Others may use internally mounted blocks which increase the size of the bottom box and are very hard to find in the dark. Our upper cam levers clamps are much easier to engage than other designs. You don't need four hands like the competition's scopes do.
