Got ambitious with my new multicolor setup (3D Chameleon)
I had some issues toward the end, in the blue parts, but otherwise it's perfectly functional and strong!
Going to do the same treatment for the upper and handguard to make it a full on USA flag :)
STLs upon request
Ok, Maybe don't do multi-color prints for firearms... Nothing catastrophic, just prevented me from finishing my range time. Back to solid black!
lesson learned
