Need info on the Savage 110 Scout rifle. Does it use the normal 110 short action? Does it have a barrel nut? Are the sights removable? Is there a full length Picatinny rail available for both models? I am building a truck gun and already have an accurate 17inch Savage barrel on a stagger feed LA and can't get it to feed properly. It seems the Magpull model in 223 is hard to find.
