How does weapon leveling work?

Only players who have played for a while would know, but I think there is someone who would be happy to answer my question.

When you level a weapon's xp so it advances to the next level, do you still get the original weapon? For example, if I level Back-roller up to Heavy-roller, would I still get the normal Back-roller?

Just a quick question which will be answered just as fast.

 

Yep, you can use old weapons.

 

Oh. Can you turn old weapons into new ones by clicking on the next level shown? Or is that just a monitor to show you how many you've unlocked? That always looks confusing... lol

 

no you know when you click and a weapon and it has small locks on them when you level the weapon you can click the weapon that you have unlocked or pick the old one i'll post a gif of it

 

So, if you unlocked Heavy Back-roller from Back-roller, you could turn a Back-roller to a Heavy Back-roller and vice versa? Cool!

 

here ya go also i think it's really cool because you can choose to be op or not

 

WOW! Thanks!

 

That and some of the older weaps are better to use. Like Horizon over sweeper, or sub-snip over smart snipe or sink hole over area strike.

 

Its much like regular grinding for leveling. You grind all day focusing on one type of gameplay and after so many hours you get a few levels.
You gotta waste a good chunk of your day/life right now and very few won't get frustrated and progress pretty fast. At times the game gets you bored and sorta sick of it so breaks are a must have. xD
