M4A1-Adv.

Okay, so I keep hearing about how all the variations of weapons are the same except looks, scopes, or ammo size.

I find this to be false.

I picked up an M4A1-Adv once in-game, and this SIGNIFICANTLY BETTER because of REDUCED RECOIL. I do own the M4, and it's my main and permanent weapon. I noticed a huge difference in recoil. The shots of the adv were always way more precise, and I ALWAYS got the kill. Compared to the M4 itself, where if I just crouched and shot, I'd most likely miss the target more times than I could count on my fingers.

IS the Adv honestly the same thing? Because it just doesn't feel like it.
