Hello, this is what I have. I don't know the mfg, it came with a MFT stock I ordered on ebay. Unsure of the manufacturer and I'm just throwing a spare buttstock in to get rid of it. Includes: (1) New Carbine Buffer (1) New Carbine Spring (1) New Mil-Spec buffer tube (1) New Castle Nut (1) New end plate (1) Used Buttstock (just to be clear, this is a commercial buttstock. It fits and locks on to the buffer tube, but it is sloppy. I want to get rid of it because it is just taking up space and is pretty much thrown in for free). Asking $38 shipped. Paypal gift or add 3.5% for fee. Will also accept a USPS MO if needed.
