I recently bought a storage tub of new AR-15 fore ends from a dealer to help him out. He needed to move out some inventory as he didn't have room for it, and I don't really get into parts but i bought them and now I'm the owner of a huge tub of fore ends. They are new in the packaging and were made by Yankee Hill Machine, Midwest industries, UTG, Magpul, and others. There are also a bunch of YHM gas blocks. I have no idea how to tell if these are good quality or if they are complete. I dont want any of them, so what do you think my best option is? are these good enough to take to a gun show and put them on the table for sale? is there a market for these things? did i just get hosed? I think there are about 30 fore ends and 10 gas blocks if that helps
