(22) Referring to FIGS. 1 and 5-8, rifle 100 can include a bullpups type rifle that has been modified and substantially altered. A bullpup's rifles configuration generally includes picatinny rails 117 on top of a receiver 118, bolt carrier group and ammunition magazine with magazine release 111 which is placed behind the pistol grip. This shortens the firearm's overall length without sacrificing barrel length. Types of bullpup rifles that can be used with this invention can be semi-automatic and automatic weapons, such as but not limited to those described in U.S. Pat. No. 5,834,678 to Kalb; U.S. Pat. No. 7,047,684 to Roh and U.S. Published Patent Application 2005/0235546 to Wonisch, which are each incorporated by reference in their entirety. In a preferred embodiment, the existing bullpup pistol grip with associated bullpup rifle trigger has been removed.

(23) The novel integrated weapon system 1 will eliminate the bullpup rifles pistol grip and replace it with a port/docking station 160 that accepts an operational handgun 200 with pistol grip 208 and trigger 206, such as but not limited to a semi-automatic pistol, such as a Smith and Wesson M&P. Types of pistols that can be used include but are not limited to those shown and described, in U.S. Pat. No. 5,717,156 to Lenkarski; U.S. Pat. No. 6,405,473 to Petig and U.S. Published Patent Application 2006/0150467 to Poulin, which are each all incorporated by reference in their entirety.

(24) This system 1 is a fully adjustable rifle 100 that has the ability to accept most double action semi-automatic pistols 200. Inserting the pistol 200 into the docking port/docking station 160 located underneath the rifle 100 will bring the rifle into functional operation status. The pistol 100 generally should be configured with the slide 250 locked to the rear.

(25) Referring to FIGS. 1-8, there are several steps to lock the pistol/handgun 200 with the rifle 100.

(26) First, pull down the retracted trigger lever/linkage 107 which is pivotally attached by pin 108 to rifle internal trigger linkage 114. Next, tilt the pistol 200 forward (down) and insert the upper rear end 245 of the pistol 200 into the port/docking station 160 so that the horn (backstrap) 240 of the pistol 200 is above the height adjustment U shaped bracket 112 (FIG. 4). Once the rear of the pistol is inserted into the docking port/docking station 160 of the rifle 200, the user can adjust the rifle 100 to fit the handgun 200.

(27) The adjustments can include adjusting the height of the rear end 245 of the pistol/handgun 200 (in the direction of height adjustment movement arrow 109) by rotating screw 110 so that the threaded tip end of the screw 110 pushes the rear end 245 of the pistol to abut against an interior ceiling in the docking port/station 160.

(28) Additionally, the user can adjust the rear end 245 of the pistol to fit inside the larger width opening in the docking port/station 160 by adjusting width adjustment screw 113 that the threaded tip end of the screw 113 pushes the rear end 245 of the pistol 200 against an interior side wall inside of the docking port/station 160 as shown in arrows 127.

(29) Next, the user can rotate the front barrel end of the pistol/handgun 100 up into the rifles front docking port/station 160 and slide the cavity/cut-out opening 140 of forearm grip 101 to the right in the right direction of double arrow 150 (FIG. 8) about the barrel end having the pistols picatinny rail 228, which is located on the bottom of the pistols 200 lower receiver. To release the pistol/handgun 200, a switch 102, such as but not limited to a release button can be depressed to release an internal catch to allow the fore grip 101 to slide back. The slidable fore grip 101 can slide similar to the pump slide handle on shot gun, such as those shown and described in U.S. Pat. No. 4,867,039 to Dobbins and U.S. Pat. No. 6,775,941 to McNulty, Jr., which are each incorporated by reference in their entirety.

(30) Referring to FIGS. 1, 2 and 5-8, a bottom lock 103 having a rectangular plate configuration can have a forward end with a spring 120 which having a front end attached to an internal roof portion inside cavity/cut-out 140. A mid-portion of the bottom lock/plate 103 can be pivotally attached to internal opposite sides of the cavity/cut-out 140 by a pivot pin 119 that passes through pivot pin hole 121 in the bottom lock/plate 103. The outwardly expanding spring 120 can pivot upwardly facing protrusion(s) 122 on the rear of the bottom lock/plate 103 forming a locking lug 122, which can press into any of the parallel grooves (picatinny rail channel/groove 205) in the picatinny rails 228 along the underside of the barrel end of the pistol 200. The locking lug 122 fit into one of the grooves/channels 205 of the picatinny rails 228 forms a height adjustment to fix the height of the front barrel end of the pistol 200 to abut against an interior ceiling surface portion inside of the cavity/cut-out 140 of the fore grip 101.

(31) Next, the user can rotate a width adjustment screw 104 in the side of the foregrip 101 so that the threaded tip end abuts against a side portion of the barrel end of the pistol 200 pushing the barrel of the pistol 200 against an opposite internal side wall inside of the cavity/cut-out 140 of the foregrip 101.

(32) Referring to FIGS. 1, 3A-3C and 5-8, the user can connect the trigger 206 to the rifles existing internal trigger linkage 114 inside of the rifle 100. The horizontally moving rifle internal trigger linkage 114 has been modified to have an outer end with a pivot pin 108 which is pivotally attached to a vertical trigger lever linkage 107. The bottom of the trigger lever linkage 107 can have a side facing tab/attachment 123. A screw 124 having a tip end that remains pivotally attached to a mid-portion of trigger lever/linkage 107 can slide to the right or left within adjustable trigger channel 116. The user can move the lever/linkage 107 until side facing tab 123 abuts against a back of the pistol trigger 206. When the tab 123 abuts against the back of pistol trigger 206, the user can then tighten screw 124 locking the position of pivotal pin portion of where lever/linkage 107 is continuously pivotal relative to the side walls of docking port/station 160.

(33) At this point the modified rifle 100 has become fully function utilizing the pistol/handguns trigger 106. The handgun 106 has been taken out of battery and can only function as the rifles 200 trigger in this configuration. If at any time the pistol/handgun 200 is removed from the rifles docking port/station 160 the rifle 100 will be placed on safe 115 (utilizing the rifles existing safety) and considered out of operation. The handguns 200 slide 250 can be released, a round chambered, and placed back into service and utilized as a standalone weapon.

(34) This system will utilize a semi-automatic handgun's trigger mechanism to fire the rifle 100. The rifle 100 can be a fully functional weapon system only when accompanied with a compatible semi-automatic handgun 200. The two 100 and 200 will create a marriage when the handgun's slide 250 has been locked to the rear position which allows the trigger mechanism 114 of the rifle 100 to be linked to the handguns trigger bar. Once the trigger connection has been made, the semi-automatic pistol/handgun 200 will then be locked into the docking port/station 160 of the rifle 100 making the rifle 100 fully functional.

(35) In case of depletion of ammunition from the ammunition magazine in the rifle 100, the semi-automatic pistol/handgun 100 can be detached and used as a separate weapon system. During the separation, the semiautomatic pistols/handguns 200 slide 250 will move to the forward position, load a round into the chamber, creating a functional pistol/handgun 200. Once the rifle's 100 ammunition problem has been rectified, the semi-automatic pistol/handgun 200 can be reattached, making the rifle 100 operational again.

(36) The invention can be used with a rifle having any type of caliber.

(37) Although the above references fasteners, such as screws (for example screws 110, 113, 104), other types of fasteners, such as but not limited to bolts, and the like, can also be used.

(38) While the types of rifles referenced include a bullpup rifle, the invention can be used with other types of rifles, and the like.

(39) Although the drawings and description describe double action semi-automatic pistols, the invention can be used with other types of pistols, handguns and the like.

(40) While the embodiments describe a rifle with docking port/station and pistol/handgun, the invention can be used with other weapons such as a crossbow, and the like.

(41) While the invention has been described, disclosed, illustrated and shown in various terms of certain embodiments or modifications which it has presumed in practice, the scope of the invention is not intended to be, nor should it be deemed to be, limited thereby and such other modifications or embodiments as may be suggested by the teachings herein are particularly reserved especially as they fall within the breadth and scope of the claims here appended.
