I have a Colt SP1 upper that’s been sitting in my safe, and considering I have so many other projects going on, I’m looking at what the value may be.

I refrain from asking this question on forums, and usually do my own research to come up with an educated value of what I intend to eventually sell. But this one, I’m kind of at a loss, so please forgive me for asking here.

What I have is a Colt SP1 upper with barrel, no bcg, ch or dust cover, and no hand guards. …large hole upper, no foward assist and birdcage fh. Gray in color in good/VG condition.

Thanks in advance.
