I built this from a brand new Marlin X7TH Tactical. Bolt action, .308, 18" heavy barrel. I did a considerable amount of work to it to make it more accurate and comfortable. Longest range I can find around here is 200 yards, but I can make 10 shots fit in one hole.
Had to sell it a few years ago because of money trouble. Was making a deal last night and to sweeten the pot he brought this out. Sold!
