I am buying a new Maruzen APS2-SV to start sniping with. Of course I'd like to upgrade it for max performance eventually. But for now I would just like to increase power. I have read that a First Factory 170 spring or a PDI 200% spring will get my gun shooting at just under 500FPS with .20 bbs. I don't want to be shooting too hard for AA which means I need to keep it under 500FPS. What are the opinions out there? Anyone sniping currently? I know PACO owns a few rifles. What spring shoudl I get? Thanks.
