Just finished my new M5E1 with a 20" Faxon barrel. I borrowed a Vortex PST 4x16 off another rifle and had a difficult time finding the right sight picture and lock-up for the PST stock. Bought an Arken 4x16 scope and mount tonight with the hope of better results. The precision guys at the range are AI reps running $12k firesticks. Their advice is to spend more money. My wife is important in my life so budget is critical. Does anyone run an M5E1 with an Arken scope?
