1. In conjunction with a modular sleeve mounted on a conventional firearm having a stock, upper receiver with flat top, lower receiver, barrel, pistol grip, and magazine, said barrel being joined to the upper receiver, said barrel defining a forward portion of the firearm, said stock being joined to a rear portion of the upper receiver, said stock defining a rearward portion of the firearm, said firearm having a longitudinal axis running from said stock through said upper receiver to said barrel, wherein said modular sleeve is comprised of an upper handguard piece joined to a bottom handguard piece, said upper handguard piece having a front, rear, top, opposing sides and outer surface, said front and rear defining an upper handguard piece longitudinal axis, each of the upper handguard side outer surfaces having two longitudinal channels formed therein, a large and shallow upper channel and a bottom interface channel, said upper handguard piece top having a longitudinal gap formed therein, wherein a hinging element is fixed to the upper handguard piece top at the front and is adapted to pivotally join an interface element, said interface element having a plurality of fastener holes formed centrally therein, each said fastener hole being adapted to receive a threaded fastener, said handguard piece top having a plurality of heat venting apertures formed through the longitudinal gap, said handguard top piece having a plurality of fastener holes formed therein, each said fastener hole being adapted to receive a threaded fastener, a laser module adapted to being placed into the upper handguard piece top longitudinal gap, said laser module having a flat top, bottom, front, rear, and two opposing sides, said front and rear defining a laser module longitudinal axis, said laser module longitudinal axis being parallel to and partly coincident with the longitudinal axis of the upper handguard piece, comprising:

  • two, parallel elongated submodules, each submodule having a front and a rear, said front and rear defining a submodule longitudinal axis, said submodule longitudinal axes being parallel to and partly coincident with the longitudinal axis of the laser module, each said submodule front having an aperture permitting directed output from the submodule, each said submodule being positioned so that an elongated, generally rectangular space is formed between the submodules;

    said elongated rectangular space having an open bottom, a top formed by the laser module flat top and two sides formed by the said submodules, said elongated rectangular space having a side-to-side width slightly greater than an upper handguard top width; and

    a plurality of fastener apertures formed centrally in said laser module top.
