Hello to all. I have a series of questions pertaining to the M1 grenade launcher as developed for use with the 1903 Springfield. 1. Are they legal to own? 2. If so, are they actually available? 3. If so, is there some sort of price range one could expect to pay for an original? 4. Am I crazy for even asking? My reason for asking (crazy or not) is my recent purchase of a nice rifle mounted in a pre-WWII "S" stock that was properly tapped for the M15 sight, as depicted on pages 406-407 in Col. Brophy's volume on the '03. The sight and recoil pad are easy enough, but in order to fully restore the piece to "grenade launching" configuration, an M1 launcher would be great. Any insight would be greatly appreciated.
