A modular hand guard assembly serves both as a hand guard system and as an integrated interface system for mounting various weapon accessories and attachments thereto. The modular hand guard assembly includes a removable forward rail section that can be removed from the forward portion of the hand guard to provide for the installation of additional weapon accessories such as lights, optics or lasers in highly a desirable forward location adjacent to the barrel of the weapon. The modular hand guard assembly further includes a removable lower hand guard to provide access to the barrel of the firearm and an integrated modular switching and control system for use in connection with the various powered accessories mounted thereto.

The modular hand guard assembly of claim 1, wherein said locking mechanism comprises a pair of locking pins slidably engageable with said mating formations of the hand guard whereby said pair of locking pins selectively lock said accessory piece to said hand guard by preventing said reciprocal mating formations from being disengaged from said mating formations. 4. The modular hand guard assembly of claim 1, further comprising: a modular switch system positioned on said hand guard, said modular switch system including switches and at least one plug that interfaces with accessories mounted to said hand guard to allow said switches to control said accessory. 5. A modular hand guard assembly for a firearm, said firearm including an upper receiver having a forward end and a rearward end, said upper receiver further including a dovetail rail extending longitudinally between the forward end and the rearward end, said upper receiver still further having a barrel receiving receptacle at a forward end thereof, said firearm further including a barrel received in said barrel receiving receptacle and a barrel nut received around an outer surface of said barrel receiving receptacle, said modular hand guard system comprising:an upper hand guard having a forward portion and a rearward portion, and further having a dovetail rail extending longitudinally between the forward portion and the rearward portion, said upper handguard further having opposing sidewalls extending outwardly and downwardly from said dovetail rail, said forward portion including a cutout area, said opposing sidewalls including mating formations within said cutout area;a clamp removably secured to said rearward portion of said upper hand guard to support said upper hand guard on said barrel nut, wherein said upper hand guard extends from said forward end of said upper receiver forwardly above said barrel, and further wherein said dovetail rail of said upper hand guard extends forwardly in linear alignment with said dovetail rail of said upper receiver;a removable rail section including a dovetail rail and sidewalls that extend outwardly and downwardly from said dovetail rail, said sidewalls of said removable rail section including reciprocal mating formations configured and arranged to be received into said forward cutout area and to interlock with said mating formations on said upper hand guard; anda locking mechanism configured and arranged to selectively secure said removable rail section in assembled relation within said cutout area. 6. A modular hand guard assembly for a firearm, comprising: an upper hand guard having a forward portion and a rearward portion, a dovetail rail extending between the forward portion and the rearward portion and opposing sidewalls that extend outwardly and downwardly from said dovetail rail,said forward portion including a cutout area,said sidewalls including upper and lower mating formations;an upper accessory piece including reciprocal mating formations configured and arranged to be received into said forward cutout area and to interlock with said upper mating formations on said upper hand guard; anda lower accessory piece including reciprocal mating formations configured and arranged to interlock with said lower mating formations on said upper hand guard. 7. The modular hand guard assembly of claim 6, further comprising: a pair of locking pins slidably engageable with said mating formations of the upper hand guard;whereby said pair of locking pins selectively lock said upper and lower accessory pieces to said upper hand guard by preventing said reciprocal mating formations from being disengaged from said mating formations. 8. The modular hand guard assembly of claim 6, wherein said lower accessory piece is a lower hand guard. 9. The modular hand guard assembly of claim 8, said lower hand guard including a forward portion, a rearward portion, and opposing sidewalls that extend outwardly and upwardly, said reciprocal mating formations extending from the sidewalls. 10. The modular hand guard assembly of claim 8, wherein said lower hand guard further includes a dovetail rail extending from said forward portion to said rearward portion. 11. The modular hand guard assembly of claim 6, wherein said upper accessory is selected from the group consisting of: visible lights, infrared illuminators, lasers, range finders, accessory weapons, tasers and video cameras. 12. The modular hand guard assembly of claim 11, further comprising: a modular switch system positioned on said hand guard, said modular switch system including switches and at least one connection port that interfaces with said upper accessory to allow said switches to control said upper accessory. 13. The modular hand guard assembly of claim 12, further comprising: standoffs on said hand guard; andslots in a rear surface of said modular switch system that engage said stand offs thereby retaining said switch system in an engaged position on said hand guard. 14. The modular rail assembly of claim 6, further comprising: a modular switch system positioned on said hand guard, said modular switch system including switches and at least one connection port that interfaces with said upper accessory to allow said switches to control said upper accessory. 15. The modular hand guard assembly of claim 14, further comprising: standoffs on said hand guard; andslots in a rear surface of said modular switch system that engage said stand offs thereby retaining said switch system in an engaged position on said hand guard. 16. The modular hand guard assembly of claim 14, said modular switch system including a plurality of vent holes that extend therethrough and correspond to vent holes in the handguard. 17. The modular hand guard assembly of claim 6, wherein said upper accessory further includes a dovetail rail extending along a top surface thereof. 18. The modular hand guard assembly of claim 6, said upper accessory including a forward portion, a rearward portion, and opposing sidewalls that extend outwardly and downwardly, said reciprocal mating formations extending from the sidewalls. 19. A modular hand guard assembly for a firearm, comprising: an upper hand guard having a forward portion and a rearward portion, a dovetail rail extending between the forward portion and the rearward portion and opposing sidewalls that extend outwardly and downwardly from said dovetail rail,said forward portion including a cutout area,said sidewalls including upper and lower mating formations;a removable forward rail section including reciprocal mating formations configured and arranged to be received into said cutout area and to interlock with said upper mating formations on said upper hand guard;a lower accessory piece including reciprocal mating formations configured and arranged to interlock with said lower mating formations on said upper hand guard; anda pair of locking pins slidably engageable with said mating formations of the upper hand guard,wherein said pair of locking pins selectively lock said forward rail section and lower accessory pieces to said upper hand guard by preventing said reciprocal mating formations from being disengaged from said mating formations. 20.
