the one in the pic is a g36c rail, just need to make a few cuts and glues for it to work, looks good. i myself just modded a g36 scope into mine, i had previously use a g&p m16 scope, and even a 30mm rds, what evers your fancy you can do it. its about the same amount of work to do either scope and/ or rail. the carry handl on the xm8 is a slight/ gradual curve, its not egsactly flat, but either way if you get a mediumlength rail you can put it in place, but for best results, i HIGHLY reccommend you just remove the optics houseing/shell, grab a g36 side rail and mount it in place, then you retain the look of the xm8, it looks cleaner more professional, and allows you to change out the optics as you desire and the optics dont sit so high, they would sit egsactly in place of the stock one would... got that?
