I just received my Leupold Mk4 (M151) spotter back from a warranty repair and I have to give them a shout out. The spotter was repaired in 1/2 the time of their estimate, and they went through everything inside and out. This old girl was no safe queen, and it has seen hard use. They cleaned it up, fixed the canted reticle, cleaned the dust out of the lens, and sent it back. I bought this used surplus in a group buy, and they still replaced the mangled objective ring, cleaned up most of the battle scars, and included two different service repair sheets of the work they performed. I know Leupold gets no love on this forum, but they went above and beyond what I had hoped for with this repair. Thanks Leupold!
