I mounted a Zeiss Conquest 3-9x40 in a Leupold Mark 2 IMS mount on My M&P10 LE model. I really love both the scope and mount. The low light capabilities of the Conquest is amazing and really comes in handy when the deer are moving early and late. EuroOptic has a great deal on the Conquest. Zeiss Conquest 3-9x40 Zplex Reticle 5214609920 - EuroOptic.com which is $100 cheaper than what Cabelas is selling the same scope for under their Cabelas Instinct Euro label. Both scopes are actually made by Meopta and are hard to beat as the best bang for your money in a 3-9x40 hunting scope.
