Removing VFC SCAR-H front iron sight.
 

I'm interested in removing the front iron sight on my VFC SCAR-H but have no idea how I'd go about doing so. I'd rather not tinker and try it out on my own in case I end up snapping or breaking a part. I suspect I require a pin punch though the only bit of information I've been able to google is that the VFC SCAR front iron sight has a different removal process from other brands of SCAR. Could somebody please let me know how to remove it before I take a pin punch and hammer to my baby unnecessarily?
