Hey, I'm pretty new to the industry, but I've played paintball for over 10 years (I know there very different). I am trying to figure out what the average fps is for commercial fields? The company I work for is looking to potentially add airsoft to their recreational activities, and we need to figure out the average velocity of guns. Also is it very difficult to change the fps on a airsoft gun? On a paintball gun its just a simple screw that is loosened or tightened. I am looking for answers for every type of gun.. I know it can vary based on the gun, but which is more difficult? Or are they all about the same when it comes to changing the fps? Thanks.
