BVSS can be the 4.27 or the 4.4 screw spacing. If the magazine stays with the action when it is removed it is a staggerfeed, if it stays with the stock it is a centerfeed. Looking into the mag from above the centerfeed mag box will put the cartidge in the middle when feeding, and the stagger feed will alternate from left side to right side as the cartridges are loaded. I believe it has always been an accutrigger, but I am not certain.
