I initially bought a new Nikon Prostaff 5 scope (4.5-18) a few weeks ago at Bass Pro. Brought the thing home, mounted it, screwed-on the sun shade and the scope threads completely stripped out. Returned it, gave Nikon the benefit of the doubt and bought another one. Only this time to have the small elevation screw strip on the top when I tried to switch to the high profile turrets. I knew K was taking a gamble spending $500 on a Prostaff but this is ridiculous! I've noticed their prices going up and overall quality going down. I'm switching to Leupold. VERY DISAPPOINTED!
