I had one on my Knight LRH and just put one on my new endeavor and i havent had any problem with them. I like the ballistic plex reticle alot better than the circles on the Nikon BDCs. They have the Fullfield 2 combo with binoculars for 189 at dicks sporting gooods and you can go online and print a $15 dollar coupon , so the combo with binos would be $174, cant beat that. Ive also seen them on sale on cableas website for 199.
