This lightweight Picatinny rail is designed for the Adventure Force (Dart Zone) Nexus Pro foam dart blaster that is made by Prime Time Toys. It attaches to either sides of the handguard. Photos show the different position(s) that it can be installed. It snaps onto the handguard slots and can be attached and removed at will.

This light weight Picatinny rail is made out of polymer (a type of plastic that is strong and resilient). And it is made to Picatinny specification.
