I like the 50 mm objective, we are talking 10mm and with talley rings you only need the medium rings, I put mine in quick detach and keep a strait 6X40 in my pack incase of a fall or damaged scope, release the leavers, pop in the 6 powere and go, my 3.5-10X50 is zeroed for 180gr tsx and I have a 3X9X50 zeroed for the 130 gr TSX, great rifle and does it all:-)
