Remington-Knife Glitch/Bug

Whats up guys,

I was playing around with the new dog tag gun and noticed something hilarious.
There is a problem while reloading, you can instantly spam right click to knife in a row.

Im guessing this a glitch of some sort?
I've gotten a five kill streak with it, and people kept calling me a cheater (uknowwhatimean.)

Will this get fixed? (if its a glitch, and im pretty sure it is..)

I would use the gun just because of that, because its really fun to play with.
Im just afraid if i get reported, and the GMS/whoever reads these tickets dosen't know of this, I will get banned.
