Mock Integral Suppressor for Nerf Rival Mirage/Challenger

A custom barrel attachment designed to give your Rival blaster a sleek, suppressed aesthetic. Featuring a hardware-less muzzle shroud, it's specifically made to fit the Nerf Rival Mirage and Challenger.

Both blasters feature a moulded but non-functional lug at the muzzle that appears intended for barrel attachments. This model takes advantage of that geometry to create a purpose-built cosmetic accessory that mounts directly to the existing lug. The design aims to replicate the look of an integral suppressor, forming a large cylindrical shroud around the muzzle that blends into the front of the blaster for a more tactical, cohesive profile. It does not affect firing performance; it is purely a visual upgrade.

Fit and Installation

This model is intentionally designed with very tight tolerances. I prefer attachments that do not rattle or shift during use, so the coupling pegs and inner ring create a firm press fit onto the Mirage/Challenger lug. Once installed, it is effectively intended to be a permanent attachment. If you prefer a removable or modular fit, you can simply sand the coupling pegs and inner ring until the attachment reaches your desired level of tightness.

Compatibility and Calibration

I have personally verified compatibility using my own Mirage and Challenger blasters. However, small manufacturing variations in the lug geometry can occur between units, and your printer's accuracy can also affect fit.

For best results, it is strongly recommended to print the included test piece first. This allows you to:

• Confirm your printer's dimensional accuracy

• Adjust print settings if necessary

• Check the fit against your specific blaster before committing to the full print

Unless you specifically want a noticeably front-heavy blaster, I recommend keeping infill at 20% or lower. Higher infill offers next to no practical benefit for this part and will mainly add unnecessary weight to the front of the blaster.

The model is designed to be relatively printer-friendly and typically will not require support structures, but it is 227 mm tall, so be sure your printer can support such a large build volume. For best results, print it with the muzzle end resting on the build plate, placing the coupling pegs at the top of the build volume. Consider using a raft if you think the thin inner walls are prone to separating on the first few layers.
