I may use this guide for my First Order Stormtrooper blaster. It's a Rampage reskin, but the painting principles should still be the exact same as on a Raider.
We currently sell the barrel kit for our Destiny blasters! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-DAI-CERIUIM.html and ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ScEPSDLzGUY.html
Thanks! Yeah the Nerf Raider is pretty easy to find at 2nd hand stores to turn into a Sith Trooper Blaster! We'll be adding a link to the gun site 3D print files on thingiverse.com this evening. 👍
We use Krylon and Rustoleum spray paints! I always start with Rustoleum automotive primer grey or Krylon White primer as the base coat depending on the project.
