I always liked the looks of the xm3, especially when you'd see in country pics. A friend was gathering parts to build one, as close as possible. He gave up on some parts and decided against 308 and went 6.5creed. I can tell you that after shooting it he and I hated that stock. Even with a scope mounted as low as possible, you still need to build up cheek area. Also that grip sucks if you spent a little time with a3-a5 mcm or most manners. Im sure ill catch hell for this but a "modern" xm3 would be similar profile 6.5creed in a lrh(not sure if it supports a nv bridge) or a prs1 or 2(whichever is the sloped butt stock bottom) with mini chassis or minimum bedded with ai dbm.
