I bought a FXP in .308 with an Accutrigger, right before I left on a trip to Afghanistan. The rifle shot OK, about 2" at 100M. When I get back I will have money and I intend to start ordering parts while I am here. Which brings me to my question. What are the best upgrades for the money? A new stock is a must and so is new glass. Are there any other major considerations?
