View Full Version : WTT KAC M16A4 rail system for M4 rail system

I have a KAC A4 rail system in original box with documentation and accessories. I would like to trade it straight up for a KAC M4 system. The set is in great condition and has spent the last three years on my safe queen AR-15. I'd be more than happy to provide pictures upon request.
