Hello got a new job and looking to get this at the first chance I get.... however im wanting to use it as a DMR and was wanting higher gps. On Evike.com they say it shoots 400fps but is upgradable to over 500fps, yet they don't say how to and I couldn't find any specifics online. I was already planning on adding a tbb (6.01 or 6.03) but what other upgrades would I be needing to get to get that 500+ gps? Thanks in advance for any help!
