I'm a believer in Nikon scopes.
I had a 4x40 buckmaster on my slug gun for probably 12yrs.
It broke last year so I sent it to Nikon to get fixed. Well I guess it was unfixable.
So I was sent a new 3x9x40 buckmasters because the 4x is no longer available.
I was disappointed cause I really liked the straight 4x on my slug gun.
But Nikon did stand behind their warrenty.
I have a prostaff 4x12x40 for sale in the for sale section on here.
The only reason I'm selling it is cause I had it on a Rem. 308 that's since been replaced by a 3x9x50 buckmasters.
