not bad. you can tighten a bit the design around the components if you feel like it, but popups like that need to be wide too. if you need some more weight you can get those wedges down to Alu instead of Titanium.
iirc batteries empty pretty fast with two of those bursts. maay want to get more batteries in there. 96kg of weapons on a MW popup is a hell of a lot of weapons weight imo, you could go with a bit less. external armor would be helpful because HS and such won't give you a break.
