I recently purchased myself an M1A NM SS barrel etc etc.. I want to mount a scope on her for long range shooting. (i.e past 800 yards.) I have looked into a few of the options at hand and seen the McCann pop up several times, the Sadlak and a few others. I would be curious on the input. Keep in mind that the money I can put towards my M1A is whatever I can save from my G.I bill eating ramen. I'm also looking at putting the Nikon buckmaster 4.5-14X40 Mildot on there. Any suggestions on that would be appreciated as well. I have heard of issues with the USGI specs not fitting and needing a custom fit.. I hope that isn't the case.
