I personally find myself using the M16A3 more then anything. Not because lack of GP. Just because its an alright gun, it isn't bad with accuracy, so I can crouch and hit far away targets by using short bursts.
G36E i reckon is the best gp gun by far. It's not overpowered though, you still need to know how to use it. Just spraying will screw you up pretty bad. G36E teaches you how to tap the gun. Contrary to V1KASH's statement, i reckon skill is required to use the g36e to maximum potential legitly
I've used th g36e and the m416 on par before. Put both of them in my backpack with an acog on m416.. I reckon I did much better with my m416 with acog scope.. Probably cause of my rankin but m416 is a he'll good gun.. Much better than the g36e because the accuracy, good damage. It's my personal headshot machine but together back on topic, the g36e is allright. Over used, overpowered but teaches you how to control spray and recoil on any weapon. It is a good weapon for starters
No I do not make game hacks anymore, please stop asking.
