After new update, the golden m4 became garbage

after new update,the golden m4 was not only changed surface,also the FUNCTION was changed . the first golden m4 has small recoil, five bullets can shot on one point, but right now the golden m4 even worse than GPm4. MORE RECOIL AND NOT STABLE . i do not know why player spent 150$ just for a GARBAGE?? IF Z8 WILL NOT CHANGE IT BACK , I WILL NEVER USE ANY $$$ TO BUY ANY ZP. I SWEAR !!!!

THERE ARE THE FUNCTION BE CHANGED:
1.MORE RECOIL
2.NOT STABLE AS BEFORE
3.EVEN NOT ACCURATE AS GP M4.

I DO NOT CARE ABOUT THE SURFACE, I PAY FOR WDF FUNCTION, NOT FOR A GARBAGE!!
