Best Springs for Nerf Gun Upgrades

If you’re a Nerf enthusiast looking to take your blaster battles to the next level, spring upgrades are one of the most effective and affordable mods out there.

Upgrading the internal spring in your Nerf gun can significantly increase its firing power, range, and overall performance. In this guide, we’ll walk you through the best springs available, how to choose the right one, and some important safety tips. Let’s get into it!

How Springs Affect Nerf Gun Performance

The spring is the heart of a manual Nerf blaster. When you prime the blaster, you’re compressing the spring. Upon firing, the spring releases energy, propelling the dart forward.

By replacing the stock spring with a stronger aftermarket one, you can:

• Boost the dart velocity (measured in FPS)
• Improve accuracy over longer distances
• Give your blaster a satisfying “kick”

But keep in mind — stronger springs mean tougher priming, more wear on internals, and potential safety issues if you’re not careful.

Types of Nerf Gun Springs

Not all springs are created equal. Here are the common types you’ll encounter:

• Stock Springs: These are the default springs included in Nerf blasters. They’re usually designed for safety and low stress on internals.
• Aftermarket Upgrade Springs: These range from 5kg to 14kg in tension, offering a wide variety of power levels.
• Custom Springs: Some modders cut or stack springs to create a unique tension setup, but this requires more experience and care.

Each spring is usually designed for specific blaster models or categories, like the Nerf Retaliator, Longshot, or Rampage.

How to Choose the Right Spring for Your Nerf Gun

Here are some factors to consider when picking a spring:

• Blaster Compatibility: Not all springs fit all blasters. Always double-check model compatibility.
• Power vs. Prime: A 12kg spring might sound awesome, but can you prime it repeatedly during a game?
• Experience Level: If you’re new to modding, start with 5kg–7kg springs before diving into the heavyweights.
• Blaster Use: Want high FPS for competitive games or just more fun in backyard battles?

Match the spring to your goals and comfort level.

Spring Upgrade Safety Tips

Before diving in with your screwdriver, take these safety tips seriously:

• Wear eye protection while modding — springs can pop out unexpectedly.
• Test your blaster in a safe area to avoid accidental injury.
• Don’t overpower your blaster. Super strong springs can crack plastic parts or break internal seals.
• Keep it legal. Some places have limits on modded blaster strength — especially in public games or Nerf wars.
