    Exactly as advertised. Mine had all of the parts as well. Picked up a great original stock set and now I'm ready to rock.

    overall good. all parts were there

    Posted by shadow on Jul 17th 2020

    So i did get all the parts which is what i was hoping for Everything had carbon on it which is understandable. Most of the Parts were in good shape some had some finish missing. No rust other than some minor stuff on the fsb. The upper looked not as good as the other parts and it appears someone spilled white paint on it in one area. Also the finish looked like it was in various states of decay. Inside looked very fine just the outside i would rate 2/5 Shipped fast. Overall good

    Perfect part 2

    everything was there and in great shape. About 75% finish left on the upper, and after cleaning all the parts from dirt and a tiny amount of rust it the look is beautiful, like it just came out of a video game. You can tell the soldiers used it but not enough to destroy or break anything, all surface damage, but mechanically flawless. It took six days to get here. Thank you guys so much!

    Better Than Advertised

    To my surprise the receiver is actually in fairly good condition, There is a superficial gash on the carry handle near the front of the receiver. Finish is probably 75% there. The "C" marking on the carry handle has been sanitized (Milled off using an endmill I assume as there is a round divot in it's place) the "M" marking remains. The BCG is hardly used and the bolt head is almost new, probably less than 500 round through it as there are no wear marks. On top of all of that the bolt glides like butter inside of the receiver. My particular kit had every part and none missing. My only gripe is that the FSB was really rough and rusted, but I was gonna get a new one anyways. I would absolutely buy again.

    PLEASANTLY surprised

    Ordered the kit thinking a grade C kit would be serviceable but not excellent. I bought it fully expecting it to not be complete and I was ok with that. Shipping was excellent and prompt, once I stripped the receiver of black paint and did inventory on the parts, everything was there and in excellent condition. Minor wear where expected, but highly recommend for a retro build!
