Just to flag that your main mount is underequipped as it only has an aux weapon. As I imagine you want an Aux weapon for Hunter so don’t want to do a straight upgrade to a Charged Blade, if you swap your RPG so it’s in your main slot and your segment knife is in your Flex slot then the flex slot will let you mount 2 Aux weapons rather than just one so you can have:
MAIN MOUNT: Rocket-Propelled Grenade
FLEX MOUNT: Segment Knife / Whatever extra Aux weapon you want
HEAVY MOUNT: Heavy Melee Weapon
