Trigger guard for a firearm having a magazine well attachment

A reversible modification to the gas block of a machine gun reduces the rate of fire to the machine gun's design rate for use when a suppressor has been added to the barrel and which suppressor would, without the present modification, elevate the firing rate from the machine gun's design rate. The modification is the use of a stem inserted into the bore of the gas block nozzle to further limit the combustion gas being delivered to the machine gun's operating group. A hole formed in the stem restricts gas flow. The stem seats against the gas block nozzle and is held in place by the cap covering the gas block but may alternatively be held in place in several alternative ways described. Removal of the cap allows the stem to be removed from the gas block when the suppressor has been removed from the machine gun barrel.

The present invention is a T-rail that is capable of supporting, in the preferred embodiment, a day and night optical sights, image intensifier and thermal imaging device (scope) and an infrared laser designator. The scope is supported on an upper rail while the designator is supported on an extension that extends perpendicularly away from the upper rail. The T-rail supports these two objects in alignment so that when the T-rail is removed from the weapon and subsequently replaced, the two objects remain in alignment. The T-rail is designed to be mounted to a standard Picatinny rail and comprises a jaw and flange along its bottom to facilitate this mounting. The jaw has a top surface and a bottom surface that matingly engage the top and bottom slope of one side of the Picatinny rail, while the flange has only an upper surface that rests along the top slope of the other side of the rail. A clamp that engages the exposed bottom slope of the mounting rail and the body of the T-rail is used to secure and lock the T-rail in place alone the mounting rail. The attachment device, including the jaw, flange and clamp, are designed so that the T-rail may be mounted in either direction on the mounting rail. In other words, the scope and designator may be mounted for either a right handed or left handed shooter.

The present invention is a handgun having a polymeric frame with metallic rails that are inserted within the frame after the frame has been formed by a molding process. The rails are inserted into recesses formed in a channel within the frame, before the frame has completely cooled and contracted. The rails comprise a pair of front rails and a pair of rear rails. The rear pair of rails are positioned within rear recesses and held in place by the sear block. The front pair of rails are positioned within front recesses and held in place by a plurality of metallic parts. The parts include a horseshoe, an unlock block, and a spreader block that are positioned between and matingly engage the front rails, thus securing them within their respective recesses.
