In need of a part. I've had two of these volunteer arms mark 45 that some clowns tried to full auto and destroyed. I finally have the project to build a working gun complete except for one part. If any one out there has a seer I would be extremely excited to take it off your hands. This gun is a gift for my best friends nephew and this is all I need to finish the rifle for the young man. If anyone could help I'd love ya forever.
