Figure 5. Aiming post light M41-major components. 5. Differences Between Models a. Major Differences. The major differences between aiming post lights M14, M41, and M43 are in the components that make up their optical systems and in the case constructions with their particular bracket arrangements. b. Differences Between Cases. Cases differ in their clamp arrange- ments which are constructed to fit the aiming post used in conjunction with the specific aiming post light. The various cases and their clamps are illustrated in figure 7. Another difference between cases is that aiming post lights M14 and M43 have their clamp at the center of the case and are closed at each end by a cover and cap. The clamp of aiming post light M41 is formed by one open end of the case. c. Differences in Reflector Assemblies. Reflector assemblies are similar in construction and appearance. The only difference between them is the manufacturing specification of the finish and polishing of the reflector of early manufacture. Reflector assemblies for aiming post lights M14, M41, and are identical and interchangeable. The finish in the reflector assembly (fig. 5) for M41 of early manufacture is a dull unpolished aluminum. Component parts of the optical sys- tems of aiming post lights M14, M41, and M43 are shown in figures 4, 5, and 6. 7
