While both the guns are fairly similar, considering there both related to each other. which gun do you like using better? Do you like one over the other because you can use different attachments or because of the others look and feel? Maybe you like using one in the campaign but the other one in multi-player? Maybe you also are still deciding weather to use the SCARAB or SCAR like me.

Here are the stats each gun has feel free to comment about them or use them in your argument!

I personalty am leaning towards the SCARAB for its light-weight and silencer attachment. I also like it because of its higher fire-rate making it more of a sub-machine gun. However, I do like the SCAR's look and enjoy being able to use many under-barrel attachments.

I like the fire-rate with extended mags, perfect for me. I really want to learn the grendal buy my patience is low for that gun. I also like the SCARAB in the campaign too.

The Scarab should do as much damage as the Scar in short range situations. It's rapid fire but slower to kill than the Scar. It should kill just as fast in QCB.

I prefer the scarab, I've picked it up after killing someone since I don't have it unlocked yet and I'm better with it in multiplier, I also prefer it in campaign, but if I have a pistol with a silencer then I prefer using the scar i campaign. Just depends.

I totally agree I think it would be great if they made the SCARAB better in CQB, since the made reason its supposed to be different from the SCAR is to be me fit for CQB. Maybe they could just lower the weapon damage on the scar since most people believe it to be OP. That way trolls would be happy and then the SCARAB would become the better chose for CQB.
