WA SCW Infinity Expert 6" Upgrades
 

I am currently in the process of ordering a Western Arms SV Infinity Expert 6" and would like some help on what parts I would need to upgrade to use Green Gas and increase power? I've already decided to get the Silver 6" PGC aluminum slide which is the most important. Any suggestions would be much appreciated.

All you really need is either a metal slide and a stronger recoil/hammer spring, or an AI flow restrictor with a stronger hammer spring. SVI Experts are very hardy guns.
