A non-firing rifle that emulates a semi-automatic or automatic rifle for training in procedures for safe handling, cleaning, and field stripping of such weapons. The non-firing rifle retains the upper receiver assembly, barrel assembly, and ammunition magazine of the emulated rifle, as well as some of the components of the lower receiver assembly of the emulated rifle, but substitutes a modified forging for the lower receiver forging of the emulated rifle. Unlike the lower receiver forging of the emulated rifle, the modified forging has no cutouts to allow a trigger or hammer to be installed. A cutout is provided in a bottom wall of the forging, however, to allow installation of a pseudo-trigger. Accordingly, it is incapable of firing a live ammunition round.

The training rifle of claim 1, further comprising an ammunition magazine dimensioned and adapted for insertion into the magazine well, and magazine catch means mounted to the forging for alternately locking the magazine within the magazine well and releasing the magazine from the well. 3. The training rifle of claim 2, wherein the left and right walls of the central portion of the lower receiver forging are apertured, a lower, rear portion of the upper receiver assembly has a depending, rear apertured lug, and the means for attaching an upper portion of the lower receiver forging to a lower portion of the upper receiver assembly includes a rear takedown pin insertable through an aperture in said lug and through the apertures in the left and right walls of said central portion when said apertures are aligned. 4. The training rifle of claim 3, wherein the left and right walls of the front portion of the lower receiver forging are apertured, a lower, front portion of the upper receiver assembly has a depending, front apertured lug, and the means for attaching an upper portion of the lower receiver forging to a lower portion of the upper receiver assembly includes a front pivot pin insertable through an aperture in said lug and through the apertures in the left and right walls of said front portion when said apertures are aligned, and wherein the bottom wall of the forging has a recess to receive said front apertured lug. 5. The training rifle of claim 4, wherein the means for attaching the front end of the upper receiver assembly to the rear end of the barrel assembly includes a hollow, cylindrical, threaded extension at a front end thereof, and the barrel assembly includes a barrel having a straight, cylindrical bore that extends longitudinally from a rear end to a front end; a front sight mounted on a front portion of the barrel; upper and lower hand guards mounted on an exterior surface of the barrel that extend longitudinally part way from the rear end of the barrel assembly toward the front end thereof, each guard having a rear end and a front end; a slip-ring insertable over the barrel between the front sight and the front ends of the hand guards for securing the hand guards to the barrel; and a barrel extension that is coaxial with the barrel and extends from a rear end of the barrel into the threaded extension of the upper receiver. 6. The training rifle of claim 5, wherein the barrel assembly further includes a front sling swivel that depends from the barrel, and further comprising a rear sling loop that depends from a rear end portion of the buttstock. 7. The training rifle of claim 6, wherein the barrel assembly further includes a flash suppressor attached to the front end of the barrel. 8. The training rifle of claim 7, further comprising a rifle sling for mounting the rifle on a shoulder of a rifleman, said sling having a front end attachable to the front sling swivel and a rear end attachable to the rear sling loop. 9. The training rifle of claim 8, wherein the training rifle emulates an M-16 rifle and at least the following are component parts of the training rifle and are identical to the same component parts of an M-16 semi-automatic or automatic rifle: upper receiver assembly, bolt and bolt carrier assembly, bolt catch, bolt catch spring, magazine catch, barrel assembly (except the rifle barrel), buttstock, buffer, buffer detent, buffer detent spring, buffer spring, receiver extension, ammunition magazine, pistol grip, means for attaching an upper portion of the lower receiver assembly to a lower portion of the upper receiver assembly, means for attaching an upper portion of the pistol grip to a lower, rear portion of the lower receiver assembly, front sight, upper and lower hand guards, slip-ring, barrel extension and flash suppressor, and safety selector. 10. A lower receiver forging for use in a training rifle that emulates a semi-automatic or automatic rifle, said emulated rifle including an upper receiver assembly, bolt and bolt carrier assembly, a lower receiver assembly that includes a buttstock having a longitudinal bore, and an ammunition magazine, said training rifle including an upper receiver assembly, a barrel assembly, a buttstock having a longitudinal buttstock bore, a receiver extension tube that is insertable into said buttstock bore and having an externally-threaded front end, a buffer reciprocally slidable within said tube and urged in forward direction within the bore by a buffer spring that engages an annular ridge of the buffer, a buffer detent for holding the buffer and buffer spring within the tube and for selectively releasing the buffer and buffer spring from said tube, a pistol grip, and an ammunition magazine, said forging comprising: a rear portion comprising buttstock attachment means by which said forging is attachable to a front end of a buttstock of the training rifle, said means including an upstanding ring having an internal diameter slightly greater than the diameter of the buffer and internal threads for mating engagement with the threaded front end of the receiver extension tube; a front portion, said front portion including transversely spaced-apart, vertical left and right walls of equal size joined by a first vertical front wall, and a central portion intermediate the rear and front portions, said central portion including longitudinally-extended left and right walls of equal size joined by a second vertical front wall, a flat, horizontal top wall, a bottom wall, and the buttstock attachment means, said bottom wall having a trigger access cutout, thereby defining a substantially closed interior space, means for attaching an upper portion of the pistol grip to a lower, rear portion of the forging, a trigger guard that depends from the bottom wall of the forging, means for attaching an upper portion of said forging to a lower portion of the upper receiver assembly; wherein the first front wall and the left and right walls of the front portion of the lower receiver assembly cooperate with the second front wall of the central portion of the lower receiver assembly to define a magazine well for insertion of an ammunition magazine. 11.
