It really depends how you want to play. What perks, attachments and play style you want to use should determine your weapon. At close range with a rushing play style I would take the Honey Badger but the MTAR-X can compete. At long range the AK-12 is a great choice but the kill time is slower than the Remington. The AK-12 looks average on paper but I would take it over the Remington. Once you have the AK-12 in your hands it seems like a flawless weapon.

I'll put my overall vote on the AK-12 though

First off the honey badger would be better for pub stomping than both of the others but the Remington r5 is better for competitive such as gb's and the ak 12 is the in between gun hope this helped you out.

The Remington is really underrated in pubs

Remington R5 is defiantly the best, I'm a gb player so I would know
The attachments I use are Red Dot and Armour Peircing
This Gun kills people in 3 bullets through walls, have fun ;)

For the Remington Extended Mags is better than Armor Piercing... It comes in useful more. And the Remington is good in GBs but Diamondz plays pubs in which the AK-12 is better
