I am looking to buy a Nightforce scope , either the 15x or 22x and i cant decide which one to get. I am building rifle on a Mcmillan A-5 stock, badger USMC rings, Badger M5 bottom metal, Timney trigger, Badger Titanium recoil lug, surgeon rifles KMW bolt knob, Us Optics 20moa scope mount, Krieger MTU 26" Barrel, Badger FTE muzzle brake. I am really not going to be doing much shooting past 8ooyrds. I was also wondering will the Badger USMC rings (1.031 hight) be enough clearence for the 50mm obj. and Krieger MTU barrel?
