I am in the market for a 50 cal rifle. Like the looks of the McMillan line but question the cost for my casual shooting. I am leaning in the direction of the new AR50 from ArmaLite. Can I get some info from someone who has shot and/or owns one? Info on scope mounting, bi-pods, accuracy, ect. would be helpful. Is it worth buying the cheaper AR50 and spending what I would spend on a McMillan, on a scope and ammo, or should I bite the bullet and get the McMillan?
