Abstract
A stock bedding system for a firearm is disclosed. In one embodiment, the stock bedding system includes a stock having a pair of bearing surfaces that are configured and arranged to mutually engage a mating pair of bearing surfaces formed on the barrel-receiver assembly. At least one of the four bearing surfaces has a predetermined convex surface profile which causes the barrel-receiver assembly to roll in an angular direction away from one lateral side of the stock towards the opposite lateral side when the barrel-receiver assembly is mounted to the stock. The convex surface profile acts to tighten the engagement between the opposing bearing surfaces of the barrel-receiver assembly and stock providing a secure and vibration resistant mounting. In one embodiment, the convex-shaped bearing surface is defined by a pillar lug mounted in the stock which engages a mating substantially flat bearing surface formed on the barrel-receiver assembly.
