I have a Troy TRX Extreme 13" rail that was never mounted, only taken out of the box to inspect / mock-up. It is in perfect condition, and comes with a noveske TRX QD Sling mount & Noveske QD swivel.

I paid ~$230 shipped for the set-up and im just looking to re-coup some of what I paid.
Price: $200 shipped to your door or best offer
I can also do a local FTF here in the Windsor CT area.
