This is a Windham Weaponry Carbon Fiber AR15. The receiver is a carbon fiber composite and the rifles weighs a little over five pounds. I purchased it about 8 years ago with the idea of putting a carbon fiber barrel on it but then realized those cost more than the gun. I shot one magazine through it and left it in the safe ever since.
I'm interested in selling it to buy a gaming laptop prior to deployment or trade for something else. I can throw in a couple 100 rounds of ammo to sweeten the deal if needed.
