First off, I have zero knowledge of the MP5, AP5, etc. I know, i know...i'm missing out. I bought a bunch of AR parts from a guy locally and he just threw in these parts. Looks like a lower housing and endcap? The lower housing has a dented metal piece by the front takedown pin as seen in pics.
My question is do these parts have any value? If so, how much is it worth? or should I just chuck it in the trash? I have no intention of building a MP5 style gun.
TIA
