The Keystone, a top-loading Roc (Mega Gryphon)

You still need the base Roc file set for the rest of the blaster. This is only the experimental magwell and rail parts needed to make it top-loading. The Roc files can be found here . Here in Pennsylvania, we have a standard configuration of Gryphon we use that we like to call “the PA Special”, with one of its signature traits being the top-loading port in the magwell, which is becoming increasingly common on a lot of Gryphons today. However, for our HvZ games that frequently require Mega, we wanted a solution. When the Roc was released, we immediately knew what had to be done: give it the PA Special treatment. And so now, we have the Keystone! These are parts for your Roc that will allow you to top-load your magazine without ejecting it from the blaster. Included in the files are: Keystone Magwell Front Rail (with loading port built-in) Rear rail For best results with the top-loading, use Moose magazines and Accustrike/Accufake Mega darts. Nerf-brand & similar magazines have too tight feed lips to easily allow top-loading. Normal Mega Darts are too tight around the base of the dart head to easily load into the magazine.
