What are these things?

[ob'98]

Pic 1 is mag loader for M3 greasegun as already stated. Pic 2 is the charging handle from an M3 greasegun, later discontinued in favour of using the index finger to cock the weapon. Pic 3 is a scope rail for an AR15/M16 with a carry handle. Good luck with the fourth one but don't throw it out, someone will want it!

Thanks guys for the feedback. I bought a bunch of misc. stuff and these items were in the lot. I don't want them and would like to sell them if they are worth anything. If they have little value I have a friend with a Class III and he may want the grease gun items for grins...if so I will just give them to him. ??
