I put quite a lot of effort to level up to lv 27 just for scarab, but its not as beautiful as i expected and different from what i learnt from others.
scarab is said to be a beast, but i found it very hard to hit in mid-range, no hit in long-range, its recoil for me, is terrible, scarab's 3 shot burst wont hit the same spot. so i have to run away when spotting enemies out of scarab's range. compared to scarab, scar can be used as mid-long range sniper riffle, accurate, much less recoil, 2 quick burst can get a solid kill. so i had to switch back to scar with assault scope after scarab is unlocked. now the problem is i have completed all scar assessments. scarab becomes my primary weapon.

for me, scarab is just like mp5 in cs, scar is like aug. it usually takes me a entire magazine to get a kill in mid range. I need some advice on how to use scarab.

Use it with red-dor sight, or laser and silencer.

aim enhance will help you.

Well dont use scarab ass long range try to get closer and if ur usin red-dot use aim enhance but if ur aim is good use rapid fire,laser sight use rapid fire.
hope it helped:)
Tip: use the Grendel lol

SCARAB with Aim Enhance is really, really a beast. Moreover, if you unlock suppressor. it will give you more advantages.

And yeah, SCARAB is more like short-mid range assault rifle, higher fire-rate, shorter carbine with suppressor option, it's semi-SMG rifle. So, bad accuracy would be a problem for SCAR users. (But for me, somehow, I think SCAR has a higher recoil)

For me, compare to CS, I think it's more like something between P90 and AK-Defender.

Feline, close range, Scarab short-mid range, Scar mid-long range, Grendel longer range XD

I haven't used scarab with silencer for a long time because of the god damn smoke.

Well you have to know which target to engage and whom to leave alone.If you are using scrab in lighthouse only engage with mid-distance target.I really like scrarb.My accuracy with it is 32+.And with added rate of fire it gives you advantage when you face bunny shotgunners.

is there any way to deal with the smoke when a silencer is attached?

I never use silencer.I hate the fact that it reduces damages and also that stupid smoke which makes it hard for you to aim.
