Nerf Canterbury for the info, we've got the next Mega dart blaster. The Magnus is a single-shot dart blaster designed for Mega Darts, as used in the Centurion. Looks like it's got a top-slide prime and has a Tactical Rail along the bottom with some decent looking iron sights on top.
Any Nerf Fan who's been following the Mega series knows that there's issues with both the Centurion and the darts it fires... so I'm interested to see if the Magnus addresses those issues or if they improve the darts. Streamline darts for the N-Strike lineup saw many different iterations to improve performance and durability, so I wouldn't be surprised to see Mega darts have the same development.
