Good Afternoon my fellow hides member, I need to help or some input. I am attending a Precision Rifle class in September 2014. I am planning to take my Scar 17 for the class. My set up for the Scar right now is I have a factory Scar 17, I switch out the butt stock for a VLTOR SCAR Receiver Extension/Stock Adapter. My Scope is going to be a Nightforce F1 or a Steiner 3x15. My question is what type of mount should I use to mount the scope. What type of bi pods would best work with a DMR/LR set up for this Scar? Should I change out the Trigger or just used the stock trigger? What type of butt stock will work well for this Vltor Scar Extension/ Stock Adapter? What type of ammo should I get to get the best result for the Scar 17? My goal is to set up a LR/DMR Scar 17 Rifle. Any input would be great. Thank you for your time.
