About Us

JSI Modding

Serving Nerfers since 2012. We offer both local & shipped Nerf commissions, INTERNATIONALLY! We are based out of Ohio/Indiana, USA.



We are a group of 3 Purdue Engineers that specialize in modding Nerf guns to be both cosmetically and functionally superior in every way possible. We also make twisted homebrews and other awesome creations. Ask for something special or give us an idea, we do it all. Check out some of our best work here. We post most of our cos-mods, homebrews and specialty items, we do not post most generic internally modded blasters (as we do way too many of those to post).
