CROSS-REFERENCE TO RELATED APPLICATION 
       [0001]    This application claims the benefit of U.S. Provisional Application No. 62/237,640, filed Oct. 6, 2015, the disclosure of which is hereby incorporated by reference. 
     
    
     BACKGROUND OF THE INVENTION 
       [0002]    The present invention is in the technical field of weapons accessories, vertical foregrip. More particularly, the present invention is in the technical field of non-lethal functionality expansion for firearms. 
         [0003]    Conventional application of non-lethal compliance devices such as but not limited to dispersing canisters requires one hand operation. The time needed to extract such a device from the carry case or holster makes this option impractical in a hostile environment as it would put the weapon holding user at risk during operations needed to deploy such a device. Major difficulties are: main weapon may require both hands to operate, and to keep muzzle control; non-lethal canisters are kept separately from the main weapon leading to need of abandoning full control of the main weapon; intentions of using non-lethal options made obvious for the aggressor giving him/her opportunity to press an advantage. The aforementioned issues leave the user no choice but use of lethal force to demand compliance. 
       BACKGROUND ART

       SUMMARY OF THE INVENTION 
       [0012]    The present invention is a Weapons System Foregrip with Integrated Deployable Compartment for Compliance Device that puts non-lethal devices such as dispersing canisters for pepper or other chemical spray irritants directly on the weapon inside of the conventional vertical or angular stabilizer grip, giving easy deployable option for the user between main (lethal) and axillary (non-lethal) devices without taking hands off the weapon and retaining muzzle control and target acquisition.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0018]    Referring to the invention in more detail, in  FIG. 1  there is a foregrip ( 10 ) with an example of perspectively oriented tab actuated spray canister ( 12 ) to be loaded inside of the foregrip ( 10 ) with deployment controls opening ( 14 ) for the Deployment controls ( 16 ) of the tab actuated spray canister ( 12 ).  FIG. 2  shows the invention from front view ( 10 ) with an example of perspectively oriented tab actuated spray canister ( 12 ). Once inserted, the muzzle of the tab actuated spray canister ( 18 ) is to be aligned with discharge window ( 20 ) on the foregrip ( 10 ). The foregrip ( 10 ) features a variety of conventional female geometry interfaces ( 22 ) compatible with picatinny rail or other functional systems where discharge window ( 20 ) is aligned with weapon system mounting rail. To load/unload the tab actuated spray canister ( 12 ), the foregrip ( 10 ) features a loading cavity ( 24 ) on the bottom of the foregrip with a clearance ( 26 ) for the activation tab ( 28  on  FIG. 1 ) on the tab actuated spray canister ( 12 ). Stopper ring ( 30 ) prevents tab actuated spray canister ( 12 ) from going too far into the foregrip ( 10 ). To hold tab actuated spray canister ( 12 ) inside of the foregrip ( 10 ), a retention screw ( 32   FIG. 1 ) or other retention mechanism is used. The tactile discharge window clearance barrier ( 34 ) provides tactile feedback to prevent the hand from accidentally covering the discharge window ( 20 ) while tab actuated spray canister ( 12 ) is deployed. 
         [0019]    In more detail, the tab actuated spray canister ( 12 ) can be loaded inside of the weapon system mounted ( 22 ) foregrip ( 10 ) using opening ( 24 ). Once loaded, the muzzle ( 18 ) of the compliance device ( 12 ) can be aligned with the muzzle opening discharge window ( 20 ) and locked using retention a screw ( 32 ) or other retention mechanism. The deployment controls opening ( 14 ) provides access to deployment controls ( 16 ) on the tab actuated spray canister ( 12 ) enabling activation of the tab actuated spray canister inside of the foregrip. 
         [0020]    Furthermore, the operation of the device is a sequence of the following actions:  FIG. 3  align canisters activation tab ( 28 ) with activation tab clearance ( 26 ) in the loading cavity ( 24 ) of the said device ( 10 ) and push canister ( 12 ) inside of the said device ( 10 ) reaching stopper ring ( 30 ).  FIG. 4  tightens the screw ( 32 ) to lock the canister ( 12 ) inside of the said device ( 10 ).  FIG. 5  To activate spray device, lower the hand grip below the barrier ( 34 ) to clear the discharge window ( 20   FIG. 2 ), reach the activation tap ( 28 ) inside of the opening for the deployment controls ( 14 ), turn activation tab ( 28 ) to active position and press down to activate the spray canister. 
         [0021]    The weapon system mounted ( 22 ) foregrip ( 10 ) functions as a standard vertical or angular stabilizing foregrip proportioned for intended functionality. 
         [0022]    The construction details of the invention as shown in  FIG. 1  through  FIG. 5  are that the foregrip ( 10 ) may be made of metal or plastics or of any other sufficiently rigid and strong material. The various components of the foregrip ( 10 ) can be made of different materials as well. 
         [0023]    The advantages of the present invention include, without limitation, the constant presence of the non-lethal compliance device on the main weapon aligned with the weapon muzzle with ability to deploy non-lethal compliance device retaining muzzle control and target acquisition. The present invention gives access to the alternative compliance action without taking hands off the main weapon. Furthermore, the present invention allows access to all of the functions for safety and activation of the tab actuated spray canister. The present invention expands functionality of a conventional vertical or angular stabilizing foregrip and can be used as such without limitation. 
         [0024]    While the foregoing written description of the invention simplistically describes a base use the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein are endless. The invention should therefore not be limited by the above described embodiment, method, and examples, but by all embodiments and methods within the scope and spirit of the invention as claimed.
