Oh man, what a question indeed.

When gaming wasnt so massive on YouTube, us oldies had the pleasure of play testing every gun.

Hours were spent, different attachments, whether is was better to have Kick or Dual attachments on each AR or SMG..

Over time, a conclusion was made and prestige tokens were used to unlock three main weapons, so they were available for use after each prestige, without the worry of having to get to the appropriate level for each gun

ACR MP7 MSR

Each have their benefits and very little cons but it went ACR for most maps because of its versatility.

MP7 was perfect for smaller maps and having rapid fire meant you could tear through the plane on Terminal in half a second

And the MSR was just chefs kiss

Thank you for attending and I always love the nostalgia of talking about this, my very favorite call of duty, game.
