M77 mkii picatinny mount - Hi-Lux Optics Ruger M-77 All Steel Long & Short Action 1 Piece Picatinny Bases

I got this instead of getting my reciever drilled and tapped...I worked for hours to get it all to fit and after 30 shots of 300wm the soft metal of the mount had dented where it was supposed to tighten so my scope went all floppy. This might work well on a light recoil rifle but now I have to get rid of this thing to do it the right way. They are discontinued for a reason.
Pros: looks cool
Cons: hard to set up, cheap for $100
