Abstract
A rail mounting system for a firearm includes a shroud on the fore end having a plurality of spaced rectangular pads with raised, rectangular top surfaces and opposed sloping sides forming an opposed pair of side walls that intersect with the shroud surface at an acute angle. The rail mounting system also includes a mounting rail having spaced apart relief sections conforming to the locations of the pads with recessed rectangular relief bottoms and opposed sloping sides forming an opposed pair of angled side walls at the same angle as the pad side walls. The side walls of the pads and relief sections are in contact with each other along at least some of their vertical distances. The pad top is spaced from the relief bottom and the shroud surface is spaced from the rail underside.
