I've got a 10.4" upper on a demo postie and am considering selling the upper. It has about 4-5K rounds through it and is used but not abused. It still is more accurate than me and if I sold it would include the buffer and a little used factory spring (I replaced the spring with a lighter one). It has been 100% reliable with good mags. Any idea what a used upper is worth nowdays?

Thanks,

Jake
