This common handgun in the Nerf N-Strike family features an installed LED sight that requires 2 AA batteries to operate. The batteries are installed in the blasters handle. It is a single shot blaster that holds 1 dart in the barrel and 2 darts in the bay below. The LED is operated by slightly depressing the trigger. After locking the plunger rearward, the blaster is fired by pulling the trigger the rest of the way. This product has been discontinued, but you can still find them online.
Oh, no! If something is wrong with your blaster, diagnose it on the Nerf N-Strike Nite Finder EX-3 Troubleshooting page.
