Would a red dot work on the forward hand guard rail on a Tapco Intrafuse stock? I'm asking because the distance between the eye and location of the red dot is relatively long. Just curious if the set up would work for a red dot style optic. I just installed the Intrafuse stock on a friends SKS and he wants a red dot. I'm hoping I could just mount a primary arms right on top of the rail without any relief problems???
