Nerf Rival Series

The series is designed for Nerfers ages fourteen and up in mind. The RIVAL series features high performance blasters for "competitive team-based play."[2] Most RIVAL blasters are magazine-fed, however, the Artemis XVII-3000 uses an internal magazine, while the Nemesis MXVII-10K is fed with a hopper. RIVAL blasters also feature a tactical rail very different from the standard tactical rail.

All products released under the series will be released under two color schemes: red and blue.
