I wish I could confirm everything but I am controllerless. It should only work for the RT. The left trigger isnt involved in this however if you want an akimbo I can probably put the same sequence on LT and make it akimbo'd. And what Jets said about the tac switch. I dont believe there is enough...
I would do it but I have no controller right now just sent mine in. However I dont like 2 bursts they dont work that well. But if you really want one Ill try to do it all I would have to do is get my old rapidfire and make it so you have to press the button everytime you want to shoot two...
I agree with matt it is so stupid that they are trying to say they are going to stop piracy with a bill as crazy as SOPA. The U.S. is a free country they shouldnt even be thinking about this.
Ive used it a few times and its totally cheap haha. I havent got a ban or anything though. Also you will love your controller its amazing. I personally use my own rapid fire that I just improved and threw on the forums yesterday it is pretty fast especially with the MK14 with rapid fire...
Just made this rapid fire before I sent it my controller. It is still universal however I have upped the MK14 speed. It is still in beta so when I get my controller back Ill work on it some more probably. Enjoy!
