B-Square mount
I obtained and installed the B-Square mount on my converted M-48. Works slick. You are limited in 'scope selection with it, though.
Leupold makes a Scout Scope, at a fixed 2.75 power. Burris also makes a 'scope. For a few $$ more I got the Leupold. Am not through with load development yet for this rifle, but so far the 'scope and the mount seem to be holding up perfectly.
