Upgrades for silverback SRS 16"

[igotfips]

Hi all, looking at upgrading my SRS and don't really know what to go for. I'm aware that a fast hop unit is a must and a new spring as it shoots 330fps on .20g out of box, but is there anything else to upgrade that's pretty basic like barrel etc that I should be thinking about doing. End goal is to eventually be shooting at just under 500fps on heaviest BB's that are legal at that fps (based on site I play). I know joules then come into factor as well but don't really know much about it tbh so wont act like I do. Any information is appreciated. As for price limit there really isn't one so any upgrades even expensive ones I am open to trying.

Thanks

To start with just buy a rapax spring and skirmish it a few times first.

Best advice is only change one thing at a time. Lots of rifles end up in a mess when too many things are changed at once.

Huge amount of parts to choose from. FAST chamber with the SBA flat hop rubber is brilliant off the shelf. Drop a SBA M150 in and you're good to go.

Then decide where you want to go from there.
