A grenade launcher system comprises a grenade launcher receiver and a grenade launcher barrel attached to the grenade launcher receiver. A trigger assembly is attached to the grenade launcher receiver at a position adjacent the grenade launcher barrel. The grenade launcher receiver has an elongate channel disposed on an upper surface of the grenade launcher receiver, the elongate channel extending parallel to the grenade launcher barrel and configured to slidably and removably receive a mounting rail. In certain embodiments, the grenade launcher system is configured to operate in an underslung configuration relative to a firearm. In certain embodiments, the grenade launcher system is configured to operate in a standalone configuration without a firearm.

Firearm sight systems have an elongated mounting rail including a plurality of transverse bars separated by intervening transverse mounting location channels extending from a rearmost channel to a forwardmost channel, the rail having an elongated upper surface, the rail defining a pocket below the upper surface and at least in part forward of the rearmost channel, and a sight arm pivotally connected to the rail and movable between an elevated position angularly offset from the upper surface of the rail and a stowed position in which the sight arm occupies the pocket. At least a forward portion of the sight arm may be entirely below the upper surface of the rail when in the stowed position. The entire sight arm may be entirely below the upper surface of the rail when in the stowed position. The sight arm may pivot on a pivot axis below the upper surface of the rail.
