The Controversy Over Gluing the Firing Pin Spring

There has been much argument and name-calling in the forums over the effectiveness, if any, of gluing the firing pin spring on air blasters. I have read a great many mod write-ups in my day and almost everybody does what you see above. For a long time, I went with the masses and followed suit. It felt good doing things that my heroes did. But then one day I stumbled upon a thread on Nerfhaven--it was the usual mod write-up, but a special guest made an appearance.
He went by the name "Just Some Bob." Arrogant prick that he is, Bob knows what the hell he's talking about. He stood up against the establishment and laid down the law--the law of Physics, that is. He showed me the light that would illuminate the simplicity, elegance, and ingenuity of this Nerf component.

When you plug your OPRV (Over-Pressure Release Valve) in an air blaster, you allow yourself to pressurize the tank more than the stock settings are designed for. The firing pin spring is designed for wimpy stock pressures. This spring can be used to your advantage. If you glue the spring, your only source of power (and speed) in pulling the trigger comes from your finger. If you replace the stock spring with one exhibiting the optimal force for your operating pressure, you can use the potential energy of your spring to aid your finger in pulling the trigger with more force. When you pull the trigger slightly, you compress the spring but don't release the air yet. As your finger fully presses the trigger, the spring power is released at the same time the firing pin releases the air. Essentially, you get the force of your finger plus the force of the spring. These benefits have already been confirmed empirically in other Nerfhaven threads. In summation, DON'T GLUE YOUR FIRING PIN SPRINGS!

  1. I have to disagree on the last words of this post....."DON'T GLUE YOUR FIRING PIN SPRINGS!"

    I find it very helpful. :)

    1. If you don't have a suitable replacement spring, then by all means glue it. Just know that your ranges will never be as good as a finger + spring combo! You also need to jerk the trigger, rather than giving a smooth pull.

    2. I agree with you on this T da B. Id rather have a smoother and better trigger pull. Some peoples fingers can't keep doing it after 2+ Hours of waring. If you dont want to glue your spring , but dont have a suitable replacement , I suggest putting on a piece of biro.

  2. Dont glue the springs, But get some foil and ball it up and push it down into the screw that connects to the button. Get some teeth floss and put it into the screw lengthwise before you put the foil in. than get some needlenose pliers and tighten it up well. Firing pin will never come loose and its not permanent
