JoeTheBane Posted January 14, 2016 Posted January 14, 2016 Hi I'm new to air soft and this will be my first gun, its a gsg mp5 522 with suppressor, new barrel fitted that goes to the end of the suppressor. What would be the rough fps on this gun? I've seen vastly varying numbers from over 400fps to just under 300pfs. Local site limit is 350fps with .2g. Could someone point me to the place to buy a spring downgrade if needed? My friend who is giving it to me says its around 360fps but hes not sure at all. Many thanks.

It's a version 2 gearbox so any spring for an AEG will fit. Just asked him today and he said there's an American version that does near 400fps and his does around 360 fps, would I be let in with 360fps? Just over the limit. How about offering to run with heavier BB's to reduce fps?
Supporters jcheeseright Posted January 14, 2016 Supporters Posted January 14, 2016 No, the limit is the limit and chrono is always worked out for a .20g BB.Putting heavier BBs in doesn't reduce the power of the gun, it just reduces the speed the BB initially goes at... an extreme example is being hit by a slow moving brick or a fast moving ping pong ball!
JoeTheBane Posted January 14, 2016 Author Posted January 14, 2016 Ok, so a spring swap is a must, I don't want to get turned away from the site, that would be embarrassing haha. So what spring model would I need, m'something' 90,100? I would like to be as close to 350fps and but remain under it. Thanks!

JoeTheBane Posted January 25, 2016 Author Posted January 25, 2016 I got it chrono'ed at my local site and it shoots under the limit at 347fps, phew
