The question is What do You think it's worth?
There are 3-4 threads asking about values, what's my XXX worth? As i've replied in those, browse the TP forums see how many items are collecting dust vs SOLD and you'll see how little just about any firearm related items is worth.
I can buy New bbls for an average of $100. To some Colt may bring the fanboi out. To others it's another used 16" bbl.
