Not really, the G36e costs 950 GP and the AK-47 and the SCAR-L or any other gun cost 800 GP.
The G36e costs 800 GP + Scope 150 GP = 950 GP.
The AK-47 and SCAR-L or any other gun cost 800 GP + Nothing = 800 GP.
As you can see, the G36e doesn't cost more than other guns.
Also, the G36e has high power and rate of fire, which is speed and power, the perfect combination. The only downside is the recoil. But as you get more experienced, you will be able to master the high recoil that comes with the gun.
I personally can jump and crouch at the same time and shoot.
