Your 39M has a lighter barrel, squared off lever, & is drilled & tapped on the top of the receiver for a scope from the factory. I have the 39M as well, my first rifle made in 1976.
Thanks.
Since I got it (11th bday) its been my favorite rifle bar none, period.
Its not a target rifle, but compared to any and all "field rifles" i've comapred it to its stunningly accurate and just a perfectly fun blast to shoot.
I shudder ot think of how many red squirrels, punks, and Al cans it claimed in my youth!
