Windham Weaponry Carbon Fiber M4?

Anyone have one of these? Saw on Slickguns that a flattop version (no sights) is selling at Bud's Gun shop for 545.00. I wasn't really considering an AR-15 platform, but geez, at that price you have to consider one just to say you have one. Saw mostly good reviews online, but it's the OG's opinion that counts, so.........

I have one and love it. Shoots true, lightweight. The finish is easy to maintain and sand doesn't get to buggered up. Works for me as a lighweight platform
Get a good piece of glass for whatever your application may call for.
