This is a modified Nerf N-strike Nite Finder EX-3 blaster handmade by IsilWorkshop. As we can see from the images, the original vibrant coating has been replaced by the steampunk styled color tone, and features subtle steampunk styled details such as brass gear, gold rivets, weathering surfaces and more. And the entire steampunk blaster has been hand painted with at least 3 coats of paint and a protective varnish for durability, while the original red light beam allows you precisely aim at your target. Apart from that, the steampunk gun comes with 4 black whistler darts.
