I'm not sure if the Gas isn't for new guys is valid anymore.
I've seen new players go a season on a KJW rifle and not be let down. They may have a couple issues but nothing career ending.
I've also seen more than a few players in their first season with an AEG that broke who never returned because they couldn't get it fixed.
There is a pretty big knowledge base around gas guns now and they've developed since the first boom a few years ago.
Airsoft, where nothing is hurt but feelings.
