Light Weight AR Handguard
thingiverse
12 inch long AR 15 Handguard. Fits a slim barrel nut. I've added a picture of the barrel nut in the images for reference. 6mm thick at the barrel nut and tapers down to 2mm thick for the rest of it. It's a little smaller diameter than your average handguard, my goal was to make it as light as possible.
