Thread: Spike's Tactical M4-gery, what's it worth?

I bought this AR recently from a friend who had to sell it due to a change in circumstances, and now I must sell it due to change in circumstances. Does anyone know what it might realistically be worth to sell? It's a Spike's Tactical with Magpul CTR adjustable stock, MOE grip, and Magpul back-up iron sight. He said it is all mil-spec and good to go for service rifle (if they're strict on having things in 'as-issued' configuration in your neck of the woods, round here it they don't really care). I'm new to the whole 'AR' world so I don't know all that much about the different parts, any input is appreciated and I can find out whatever I don't know. I'll sell it with five 30-round USGI mags, with Magpul anti-tilt followers, as well as a gun bag. The scope and riser/rail won't be included but I'm getting rid of them too.
Cheers, Tom
