Abstract
An assault rifle is converted from an original to a modified configuration having a remote trigger located forwardly of the magazine by mounting a remote forward trigger to the original rifle by means of a pair of shroud pieces which cradle the rifle's receiver, replacing the original removable trigger of the assault rifle with a replacement lever, providing a cam element movable within cam guides defined in the shroud pieces and connecting the cam element to the remote forward trigger so as to move the cam into engagement with the replacement lever upon actuation of the remote forward trigger. The parts required for conversion are readily detachable from the rifle to thereby return the weapon to its original configuration.
Claims27
A rifle converted from an original to a modified configuration, the original configuration including a barrel, a receiver including a magazine well, a spring driven hammer, a sear for locking the hammer in cocked position and a removable original trigger lever pivotable for moving said sear to thereby release said hammer against a firing pin, said modified configuration comprising:
- shroud means including cam guide means secured to opposite sides of said receiver;
- remote trigger means mounted to said shroud means forward of said magazine well;
- replacement lever means interchangeable with said original trigger and pivotable for moving said sear out of locking engagement with said hammer;
- a camming surface on said replacement lever means;
- cam means captive within said guide means and movable into engagement with said camming surface for pivoting said replacement lever;
- and
- linkage means extending along opposite sides of said receiver underneath said shroud means and operatively connecting said remote trigger means with said cam means for urging said cam means into engagement with said replacement lever means responsive to movement of said remote trigger lever;
- said remote trigger means, said shroud means, said cam means and said linkage means being removable for returning said rifle to said original configuration.
A conversion kit for use with a rifle of the type including a receiver, a barrel attached to said receiver, a magazine well in said receiver, a spring driven hammer, a sear for locking the hammer in cocked position and an original removable trigger pivotable for moving said sear to thereby release said hammer against a firing pin, said conversion kit comprising:
- a remote trigger assembly attachable to the rifle forwardly of the magazine well;
- replacement trigger lever means including a camming surface, said replacement trigger lever means being interchangeable with said original trigger for moving said sear;
- a pair of linkage members each having a forward end operatively connectable to said remote trigger assembly;
- a pair of shroud pieces mountable to the sides of the receiver of said rifle over said linkage members, said shroud pieces including cam guide means;
- and
- cam means mountable to the rear ends of said linkage members and captive within said cam guide means such that said cam means is urged into camming engagement with said replacement trigger responsive to actuation of said remote trigger assembly to thereby move said sear and release said hammer.
A method for converting an assault rifle of the type including a receiver, a barrel attached to said receiver, a magazine well in said receiver, a spring driven hammer, a sear for locking the hammer in cocked position and an original removable trigger pivotable for moving said sear to thereby release said hammer against a firing pin, to a compact configuration having improved handling characteristics, said method comprising the steps of:
- replacing the original trigger with a replacement trigger lever having a camming surface;
- attaching a pair of shroud pieces to opposite sides of the receiver of the rifle, said shroud pieces supporting a remote trigger assembly forwardly of the magazine well, said shroud pieces including cam guide means;
- mounting a cam element within said cam guide means movably into engagement with the camming surface on said replacement trigger lever;
- and
- connecting a pair of linkage members between the remote trigger assembly and the cam element such that said cam element is urged into camming engagement with said camming surface by the linkage members when the remote trigger is pulled, the camming engagement operating to pivot the replacement trigger and thus move the sear sufficiently to release the hammer from a cocked position against the firing pin.
