There will be enough limitations and conditions on that 1 moa accuracy garantee that it will really be meaningless if you get a rifle that will not shoot to this level of accuracy and you try to get it replaced.
Sounds alright but remember what they are saying, most of us know that in probably 50% of the shooting conditions we shoot in, 1 moa would be pretty good consistancy with the best full custom rifles
at 1000 yards. To garantee this in a factory rifle falls into one of those Sounds to good to be true things and it likely is.
What does that mean anyway, is it for three shots, five shots, or first shot will impact within 1 moa of your point of aim? As I said, alot of things left out that they could use to deny a replacement rifle but it sounds good.
In all honesty, you could get a Rem 700 Sendero or one of the heavier Savage rifles and with tuned handloads would likely get the same level of consistancy.
Its the conditions, just as much as the rifle quality that will limit your 1000 yard group size.
