I just had one the the most idiotic conversations ever with someone I THOUGHT was smart. Now, to be clear, I dont own a gun yet, but I'm saving for a P90. That said, I've been researching airsoft for a LONG time. Here is the conversation:
Him: But I have taken out many assault rifles with it because they can't move as fast in tight places :]
Me: thats why I'm getting a P90

tight, compact, but mad powerful
Him: They all have the same exact barrel lenght
Me: "they all"?
Him: What matters in the FPS
Him: All guns
Me: WOW
Me: thats SO untrue
Him: It's a 2inch copper pipe
Him: dude trust me I have taken a bunch appart
Me: man, I like you, but that was a fuckin stupid statement
Him:The rest is plastic that does not touch the ball
Him: airsoft guns?
Him: Not real guns?
Me: you're telling me that a P90 has the same barrel length as an M4 carbine, or an AUG?
Him: The actual component in a airsoft gun
Him: yes
Me: omg, dude, dont be a retard
Him: Have you played before?
Him: I've been playing for 2 years
Him: There is the hop up, which spins the ball
Him: Then a 2 inch copper pipe thingy
Him: Then the rest of the barrel is plastic
Him: What makes the differance in accuracy is the FPS
Sorry for showing so much of the conversation, but man...I want to bitch slap him. I dont have any issues admitting I'm wrong, but...whos right here? I'm PRETTY FUCKIN SURE that the barrel length is unique to every gun, and that you can change the inner barrel (or, 2 inch copper pipe thingy, as he puts it) to pretty much any length the body will accomodate... please...someone clear this up. I'd like to know if I'm wrong, and I'd like to be able to throw this at him if I'm right. Sorry that this is such a blindingly stupid topic, but I really want to have experienced people comment on this.
