Warface AHK Rapidfire?

I'm not "new" to AHK i mean i couldn't code you a full script, but i know some of the basics, but every time i try to run a AHK rapid fire script and go into my safe-house, i can fire the gun, but it will fire at my set speed for 5 shots then normal, then repeat, then sometimes it wont work at all, do they have anti-cheat for this? If so is there away around it, like instead of when i hold down the mouse it shoots rapid, but maybe a burst of 5 or 6 rounds? here's my script, its very simple i know, but like i said im not extremely experienced wit AHK.

Any tips to stop this blockage of my rapid fire, and how to make it a burst?

Maybe add an int with value 0;every time you shoot +1 if int reaches a specific number, increase delay?

Something like this:

0::Suspend
LButton::
Loop
int shoot=0;
{
if(shoot > 6){
SetMouseDelay 500 //maybe higher mousedelay ?
Click
int shoot =0;
}
SetMouseDelay 20
Click
int shoot++;
If (GetKeyState("LButton","P")=0)
Break
}
