I have two versions of the gas airsoft mauser. One is metal with the extended mag and one is plastic with a standard mag. The mags are interchangeable. Someday I plan on making a tactical Solo airsoft, with a red dot , light or laser sight (maybe even all three). The problem is that the magwell is very thin and the mag itself won't let you drill through and bolt through the mag well. I was thinking of fabicating an "outer casing" around the magwell out of aluminum to beef it up a little and giving me something to drill and tap to bolt the scope mount to. This won't look so much like the clasic DL-44, but it will be a fully functioning airsoft pistol. I suppose I could epoxy a plastic scope mount to the plastic mauser, but this would be too fragile to use in an airsoft enviroment. Both mausers are of the same maker and design, so somewhere you should be able to find extra standard mags if you don't want to use the extended ones.
