I have come across a shooter M61 that I have a question on. I only gave a short peak at is as I had to run for an appointment. It is not grooved but does have two sets of holes D&T'd, one set on the receiver and one set on the barrel. My short bit of research indicates that the holes were added. I have also found that Weaver made bases for the M61 #19 rear and #13 front. I am going to head back tomorrow to look at the gun more closely but it would be great to understand the scope mount situation. Any help is appreciated.
