The Stealth Ops Upgrade Kit is a Nerf product set that was released in fall of 2015 under the N-Strike Modulus series.

It comes packaged with a Red Dot Sight, a Proximity Barrel, and a Folding Grip.



The Stealth Ops Upgrade Kit was revealed after a United Kingdom supplier accidentally released the names of the Modulus kits in January of 2015.[1] It was officially announced at the 2015 New York City Toy Fair.[2]

This product set, along with the Long Range Upgrade Kit, had a running change in production, prior to the release of the IonFire and the Recon MKII, where patches of green paint found on earlier production models were removed as a cost-cutting measure and possibly as a reaction to some Nerfers disliking the green paint in the Modulus paint scheme. The later versions of the accessories feature a color scheme similar to the N-Strike Whiteout Series blasters.
