I have a bubba SMLE that shoots good, the metal work is unmodified, I would like to try a scout scope on there, the thing is the scout scope base that Brownells sells is 6" long, I measured from the receiver ring to the rear sight; it's a shade over 4", so if I put it on there and want to keep the issue rear sight, I have to lop 2" off the base, maybe it will work, who knows? maybe I will have to put some extension rings on there to get a scout scope to work with the #1 MK III*, I am left handed and would like a scout scope on there, it would make an interesting bubba, anyways, it would not drill and tap the receiver anways.
