Colt AR lower and upper. I have the takedown pin, spring, and detent in a baggie so they do not get lost, same with buffer detent and spring. It needs barrel, buffer system, BCG, CH, and furniture to be complete. It has ambi safety, Battle Arms if I am remembering correctly, but I can't remember for certain. KMS anti roll pins. Magpul metal trigger guard. 120 rounds fired before disassembly. I was going to build it into an SPR, but my interest has shifted so I will let it go to somebody else to do their build. $550 no trades on this one, no desire to part it out. Thanks.
