I put a Bushnell/Banner dusk-to-dawn on my ML, alo put one on my slug gun (Rem 870 12 gauge), both failed within 3 years. IMHO, money down the drain. Maybe the Nikon Prostaff line is worth a look, or some of the lower end Vortex's. But I think you'll come out ahead in the long run getting up to the 150-200 range. Seasons over, shop around, look for sales. (I replaced my 2 low end Bushnells with Nikons, (Omega on ML, Slughunter on shotgun), I am satisfied with both so far).
