It's only used under special circumstances. Very expensive. I based it on my special ammo.

I needed to add a second feature. It's more for utility and executing Grimm anyway.

The holograms are for both, but it's crucial for the grenade launcher mode. It's for targeting, presenting target's ranges to the user, and selecting range settings for the airburst rounds. The 2.5 form is when it transforms from 25mm to .50. The real thing can be converted like this too, but manualy. The 307 is the 25mm. The 312 is .50.
