Sure can. This is a protoype I created for what I'm hoping will be a business for me. The barrel nut I got from someone on ar15.com, it's aluminum and very similar to an NSR nut in how it attaches. The handguard and mandrel were designed using Catia and Fibersim. I then cut the mandrel from aluminum bar stock, sanded and polished until it was a mirror, laid my composite over it, vacuum bagged and cured it in an oven. After that I trimmed it and drilled the mounting holes. The handguard itself weighs 2.5 oz and is 15 inches long.
