A Simple Barrel Mod

Most Nerf mods are done on barrels to increase the force of each blaster shot. A typical barrel is made from plastic and doesn’t allow air pressure to build up, so it doesn’t maximize a dart’s range.

The plastic barrel diameter is usually larger than the dart’s diameter, so replacing the plastic barrel with a tighter barrel increases power. A simple modification is to use a brass barrel to fit your darts.

What You Need:

Here’s the most basic mod on how to enhance your Nerf barrel. You’ll need the following:

  • 17/32 in brass barrel
  • screwdrivers
  • *hacksaw or pipe cutters for cutting the barrel
  • sandpaper
  • *If you are below 16 years old, ask help from an adult to safely use a hacksaw and pipe cutters.


  • Take out the original Nerf barrel and replace it with the 17/32 in brass one.

Brass Mod Alternatives

When you change barrel specs, you will mostly use PETG, PVC, or brass. While brass is the gold standard, PETG can be as good and feels lighter. PVC is good if you’re on a tight budget.
