A while ago I purchased a 16" 5.56 MCX and a 16" 300 BLK MCX. I had planned to SBR both - and get the kits for each but only ended up doing that to the 300 BLK. The 9" 300 BLK barrel kit came in and now I have the 5.56 16" gun plus the 16" 300 BLK barrel with no real desire to do anything else with them and I'm considering selling them. What do you think I could get for the 5.56 MCX - which I put the collapsible/ folding stock on that has never been fired and the 16" 300 BLK barrel - which has 10 rounds through it as a package?  Is $2,100 for everything fair?

Well seeing you can shop around and get a brand new 5.56 MCX for around 1400.00 and barrels are under 500.00 with the 20% discount, you are a little high. Even though you say you never fired your 5.56 MCX, it's still considered used for selling purposes.

You would be doing well to get $1600 for that package

Thanks for the info guys. Since I've got the upgraded stock - I'll probably ask around $1800 then and negotiate from there.
