Gun valuation (Sig 1911 Scorpion and AR lower)

[primalmu]

Hey everyone, I'm currently selling a motorcycle and might have the opportunity to trade for a Sig 1911 Scorpion with Crossbreed SuperTuck holster and a high quality AR-15 lower (he's going to send the specs later this evening).

Now, I have no idea regarding the value of these items. It looks like the Sig 1911 Scorpion goes for $900-1000 new, so what's the value of a used one?

When I get the information on the AR-15 lower I'll post that here as well. What I can tell you is that its a Spikes Tactical lower.

Is it a complete lower?

Because a complete Spike's lower retails for $300
