Howdy,
After a lot of research I decided to put Mojo's Snapsights on my deer hunting rifle, which is a K-31. The K-31's one fault is the lack of an aperture sight and Mojo's double aperture sights looked intriguing.
I replaced the rear sight with no problems, but the front sight blade is very stuck in its ways and isn't moving for love or money.
Any suggestions?
