I have a one piece rail on my Tikka T3 made by Mountain Tactical. There in Montana and they ship direct to Canada. Good mount, mine is made from steel with a 20 MOA cant. They make it with 0 MOA and also in aluminum. Aside from that my Savage has a Ken Farrell steel mount. Also top notch.
For a scope I prefer to have more magnification than I need. I've always heard the common complaints about need a bit more power to see if it had more bone. Better to have it and not need it, than need it and not have it. So for me I like the 5-20 or 6-24 power range.
