I'm getting a 18 inch 7.62 LA Rue OBR at the end of the month and want to get some idea of what should be added. I plan on using this rifle for intermediate distance shooting. My plans are to add a prs stock, spr grip, surefire or aac break, OBR zero MOA mount, giselle trigger and a NF 5.5-20 mildot or MLR or the 3.5 -15 version. Am I missing anything? Or am I overdoing it? I had a friend tell me that he thought the 5.5 NF might be over doing it because I won't be shooting 1000 yards. Just want to get some feed back before I start dumping cash.
