In this 'structible I will be showing a simple mod for the Nerf N-Strike Modulus ecs-10. This mod will help to fix any jamming problems you may have on any flywheel blaster.
PLEASE NOTE: I am not responsible for any damage or harm done to your nerf blaster.

Step 1: What You Will Need

• a roll of duct tape (any color)

• scissors

• nerf modulus blaster

• small tray or something to hold screws

• Philips head screwdriver

Step 2: Take Off the Stock Attachment Point

This is pretty simple, just unscrew the two screws an take it off.

Step 3: Open Up the Blaster

Next, unscrew all of the screws on the blaster. You will also need to unscrew the three on the gray rail. Then take the top half of the blaster off.

Step 4: Detach the Rubber Flywheel Protector

After you unhook the rubber protector, unscrew the four screws on the flywheel cage.

Step 5: Finish It

Flip the flywheel cage over and use the scissors to cut the flywheel protector off.

Step 6: Put the Blaster Back Together

After you've finished putting the blaster back together, cut two small squares of duct tape about the size of a penny and stick them here.

This will help the tactical (tacticool) barrels fit better.
