I don't care for the open slot beside the bolt that allows snow and crud to get into the magazine.
I wouldn’t own a Barrett without a no.2 bbl. contour, otherwise I’d sooner have the the Kimber Montana.
Since I own a 270 Barrett with a no.2 contour, my only complaint is that no X-low Talley Lightweight’s are available, and the fact the small diameter bolt creates a gap open to the mag well. I’d have given up a couple ounces to have a full sized bolt. OTOH, it’s not a deal killer. You live with it...
