Plunger and O-ring Replacement Guide

简介

If your Nerf Blaster latches and releases when you pull the trigger, but doesn't fire the dart, the O-ring might be ripped and need replacing. This guide will show you how to disassemble your Nite Finder so that you can replace the O-ring and the plunger.

==Caution==

Be aware of springs under compression. Take care so these small parts do not fly off the blaster and get lost.
