This is an authentic WW2 U.S. M15 Rifle Grenade Launcher Sight kit. Introduced in early 1944, this military-issued optic kit allowed soldiers to accurately aim rifle grenades fired from standard U.S. service arms like the M1 Garand, M1 Carbine, and M1903 Springfield rifles. Kit Components: ** M15 Sight Assembly - The primary detachable 5-inch sighting device featuring an open sight and an integrated level bubble vial for zeroing high/low-angle fire. ** Mounting Base Plate - The circular calibrated dial piece that permanently screws into the left side of the wooden rifle stock. It is marked in 5-degree increments from 0° to 45°. ** Olive Drab Canvas Carrying Pouch - Stamped with "CASE, CARRYING 7160198". It features dual snap closures and an integrated rear belt wire hook. ** Instruction Sheet - An original waxy-cloth or treated-paper manual detailing installation guidelines, zeroing steps, and range tables. Note: For a complete mounting setup, two small attachment screws are typically required to secure the circular base plate onto the stock (screws included).
