Nerf Rayven

The Rayven is a medium-sized bullpup blaster that has been updated to feature long-distance performance. It is much stronger and louder than the original.

It features two tactical rails: one on top of the blaster's integrated carrying handle and the other on the right side of the blaster. It is compatible with barrel extensions, despite not being packaged with one. The blaster also features four attachment points for a sling or a Bandolier Strap: two above the muzzle and one each at the upper and lower corners of the rear stock.
