Yes, downgrade. I would like to know what spring I should put in my Steyr SSG 69 (yes I know its reputation but I like the gun =D) so that it fires at the sites new requirement for 350 fps on 0.2g. its currently in the 420 - 440 fps range. I want to use it still, so I want to get another spring so that I can use the low power one at this site, then put the normal spring in for other sites.
Anyone who can help me, with this would be much appreciated.
