Rail Extension Device

摘要

A rail extension device for a belt fed machine gun includes a first and a second section of rail for mounting auxiliary devices, the second section being rotatable relative to the first section to prevent a collision between an auxiliary device mounted on the second section of rail and the weapon when a feed tray cover is opened to reload.

主权项

1. A rail extension device configured to be coupled to a firearm, said device comprising:
a base plate having a top surface defining a first rail interface, said base plate having a first end configured to be rotatably coupled to a frame portion of said firearm and a second end configured to be coupled to a feed tray cover of said firearm, said base plate being movable about a first axis between a first base plate position and a second base plate position, said first axis substantially perpendicular with a barrel of said firearm; and a rail member having a top surface defining a second rail interface, said rail member rotatably coupled to said base plate and movable about a second axis between a first rail member position and a second rail member position, said second axis substantially parallel with said barrel of said firearm; wherein said top surface of said base plate and said top surface of said rail member form a substantially planar rail interface when said rail member and said base plate are in said first rail member and said first base plate positions, respectively; and wherein said top surface of said rail member is substantially orthogonal to said top surface of said base plate when said rail member is in said second rail member position.
