The replacement gunstock has a forehand portion with an elongated, hollowed-out depression through which a firing rod passes interconnecting the trigger in the trigger assembly with a sear mechanism in the breech. ## Claims ### Claim 1 A replacement gunstock for use in shortening the overall length of a firearm, said firearm having a barrel and breech mechanism and a separate trigger assembly, said trigger assembly having a trigger with a first upstanding finger on an upper end adapted to release a sear mechanism in the breech mechanism causing the gun to fire when the trigger is pivoted in the trigger assembly, said barrel and breech mechanism and said trigger assembly removable from an original stock of the firearm by releasing original screws, said replacement gunstock comprising a forehand portion and a butt, said forehand portion having an elongated, hollowed-out depression in its upper side for enclosing a portion of the barrel and breech mechanism, said forehand portion having pistol grip attached to its lower side a distance from the butt such that a user can support the gunstock gripping the pistol grip with one hand and placing the butt of the gunstock against the shoulder of the same arm, said forehand portion having a first aperture on the lower side for mounting the trigger assembly immediately in front of the pistol grip whereby a forefinger of the hand gripping the pistol grip and supporting the gunstock may be utilized to actuate a trigger in the trigger assembly, a firing rod in the hollowed-out depression with a first end having a collar pivotably attached thereto and a second end with a second upstanding finger for releasing the sear mechanism, said collar configured to be attached to said first upstanding finger to connect the trigger with the firing rod, whereby the barrel and breech mechanism and the trigger assembly may be unscrewed from the original stock and mounted on the replacement gunstock with the original screws, said second upstanding finger on the firing rod releasing the sear mechanism and firing the firearm in response to movement of the trigger. ### Claim 2 (depends on 1) The replacement stock of claim 1 wherein the forehand portion has a second aperture on the lower side between the butt and the pistol grip to accommodate a clip fed magazine to the breech mechanism. ### Claim 3 (depends on 2) The replacement stock of claim 2 wherein the firing rod has two bends with a straight run therebetween for routing the firing rod around the second aperture. ### Claim 4 (depends on 1) The replacement stock of claim 1 wherein a front end of the depression is notched to accommodate a firearm that has a tube fed magazine. ### Claim 5 A replacement gunstock for use in shortening the overall length of a firearm, said firearm having a barrel and breech mechanism and a separate trigger assembly, said trigger assembly having a trigger with a finger on an upper end adapted to release a sear mechanism in the breech mechanism causing the gun to fire when the trigger is pivoted in the trigger assembly, said barrel and breech mechanism and said trigger assembly removable from the an original stock of the firearm by releasing original screws, said replacement gunstock comprising a forehand portion and a butt, said forehand portion having an elongated, hollowed-out depression in its upper side for enclosing a portion of the barrel and breech mechanism, said forehand portion having a plurality of fins with a U-shaped recess for cupping and supporting the barrel in the depression, said forehand portion having a base upon which is seated a removable shoe with a U-shaped recess for cupping and supporting the barrel in the depression, said fins and base notched to provide a channel for a firing rod, said forehand portion having pistol grip attached to its lower side a distance from the butt such that a user can support the gunstock gripping the pistol grip with one hand and placing the butt of the gunstock against the shoulder of the same arm, said forehand portion having a first aperture on the lower side for mounting the trigger assembly immediately in front of the pistol grip whereby a forefinger of the hand gripping the pistol grip and supporting the gunstock may be utilized to actuate a trigger in the trigger assembly, said forehand portion having a second aperture on the lower side between the butt and the pistol grip to accommodate a clip fed magazine, said firing rod having a first end for connection to the finger on the upper end of the trigger and a second end with an upstanding finger for releasing the sear mechanism, whereby the barrel and breech mechanism and the trigger assembly may be unscrewed from the original stock and mounted on the replacement gunstock with the original screws, said upstanding finger on the firing rod releasing the sear mechanism and firing the firearm in response to movement of the trigger. ### Claim 6 (depends on 5) The replacement gunstock of claim 5 wherein the butt has a storage compartment closed with an end cap. ### Claim 7 (depends on 5) The replacement gunstock of claim 5 wherein the pistol grip has a cavity for an extra clip fed magazine. ### Claim 8 (depends on 5) The replacement gunstock of claim 5 wherein a collar is attached to the finger on the upper end of the trigger and the first end of the firing rod is pivoted to the collar. ### Claim 9 (depends on 6) The replacement stock of claim 6 wherein the firing rod has two bends with a straight run therebetween for routing firing rod around the second aperture. ### Claim 10 (depends on 5) The replacement stock of claim 5 wherein a front end of the depression is notched to accommodate a firearm that has a tube fed magazine. ### Claim 11 (depends on 5) The replacement stock of claim 5 wherein a cover plate is provided for the second aperture, said cover plate attached to the replacement stock with the original screws for attaching the barrel and breech mechanism, said cover plate having a first slot through which a lower end of a clip magazine passes and a second slot through which a bolt release lever passes, said clip magazine and bolt release lever connected to the breech mechanism. ### Claim 12 A replacement gunstock for use in shortening the overall length of a firearm, said firearm having a barrel and breech mechanism and a separate trigger assembly, said trigger assembly having a trigger with a finger on an upper end adapted to release a sear mechanism in the breech mechanism causing the gun to fire when the trigger is pivoted in the trigger assembly, said barrel and breech mechanism and said trigger assembly removable from an original stock of the firearm by releasing original screws, said replacement gunstock molded from plastic and comprising a forehand portion and a butt, said forehand portion having an elongated, hollowed-out depression in its upper side for enclosing a portion of the barrel and breech mechanism, said forehand portion having a plurality of fins with a U-shaped recess for cupping and supporting the barrel in the depression, said forehand portion having a base upon which is seated a removable shoe with a U-shaped recess for cupping and supporting the barrel in the depression, said fins and base notched to provide a channel for a firing rod, said forehand portion having pistol grip attached to its lower side a distance from the butt such that a user can support the gunstock gripping the pistol grip with one hand and placing the butt of the gunstock against the shoulder of the same arm, said forehand portion having a first aperture on the lower side for mounting the trigger assembly immediately in front of the pistol grip whereby a forefinger of the hand gripping the pistol grip and supporting the gunstock may be utilized to actuate a trigger in the trigger assembly, said forehand portion having a second aperture on the lower side between the butt and the pistol grip to accommodate a clip fed magazine, said firing rod having a first end for connection to the finger on the upper end of the trigger and a second end with an upstanding finger for
