CA M134A2 FPS question

[Chubby]

Hey all,

So I'm in the market for an M134 minigun, but I get conflicting FPS numbers from different manufacturers. Evike says the one they sell is 550 - 600 FPS and other places say they sell it with 400 FPS. Classic Army's website doesn't even give any specs on the gun so I was wondering: Are there any M134 owners here who might know what the actual numbers are?

Don't wanna become another "hey we know you blew a tonne of money on an airsoft gun, but it's over the Canadian FPS limit so fuck you we're sending it back" statistic, so I figure I'd take a shot in the dark and ask here.

Aren’t all the mini guns hpa powered? So FPS depends on pressure
