I use a Warne rail, good quality and good machining.
Not off the wall prices either.standard or 20 MOA are available I believe.
Where did you get the Warne, I've never heard of it? (I'm pretty new to long range shooting)
Ken Farrel offers a great picatinny rail and ships to Canada.
Can get it at many shops, I got mine from Frontier Firearms , they are in my town, you can click on their link at the top also.
I guess I'll be ordering a few items from them. (my wife is pissed off) Thanks.
