Calm down, Chesnokov; “you don’t have a use for it” =/= “there is no conceivable use for it”. It’s fussier than I’d want on an AR, but “bipod/VFG or grippod under, BUIS and/or co-witnessed sight above, laser and flashlight on either side”… isn’t actually an uncommon professional setup.

Quad rails… You could attach the entire SOPMOD kit and still not use up 3-4 feet of rail space.  
But someone else said it better:
 
YOU LOOK AT FINE AMERICAN RIFLE, THINK IT NEED CRAZY SHIT STICK ON ALL SIDES OF WEAPON. YOU HAVE DISEASE OF RUSSIAN OLIGARCH, CHANGE THING THAT IS FINE FOR NO REASON EXCEPT TO LOOK DIFFERENT FROM COMRADE. YOU PUT CHEAP FLASHLIGHT OF CHINESE SLAVE FACTORY ON ONE SIDE, YOU PUT BAD SCOPE OF AMERICAN MIDDLE WEST ON OTHER SIDE, YOU PUT FRONT PISTOL GRIP ON BOTTOM SO YOU ARE LIKE AMERICAN MOVIE GUY JOHN RAMBO. MAYBE YOU PUT SEX DILDO ON TOP TO FUCK YOURSELF IN ASSHOLE FOR MAKING SHAMEFUL TRAVESTY OF RIFLE OF MIKHAIL KALASHNIKOV, NO?
 
RIFLE IS FINE. YOU FUCK IT, IT ONLY GET HEAVY AND YOU STILL NO HIT LARGEST SIDE OF BARN. GO TO FIRING RANGE, PRACTICE WITH MANY MAGAZINE OF CARTRIDGE. THEN YOU NOT NEED DUMB SHIT PUT ON SIDE OF RIFLE.

You definitely want something to keep your bare skin off the metal rails so there’s nothing wrong with rail covers. I personally use a Magpul RVG.

I always figured AJ as more of an AK gal myself: simple, rugged, reliable, old fashioned, looks like farm equipment…

crappy quad rail covers  
It’s maybe not an issue with airsoft, but try spending the afternoon sometime shooting a multiple rail carbine that has neither rail covers nor a VFG and see how much flesh you have left on your support hand.

A skin like this in Counter Strike: Global Offensive’s M4 is a good idea.

Airshit with crappy quad rail covers. This person brings shame to gun dorks.

Unlike most of the others, this one looks exceedingly awesome just on its color scheme.
