Grenade sights removal

[Number 6]

I recently bought another CA legal SKS and am in the process of sporterizing it. I have removed the bayonet already, but I am unsure about the best way to remove the grenade launcher sights. I can take a saw to it but I really don't want to do a sloppy job. I've heard that there is just a pin holding the sights in there and I can take a punch and push it out. Does anyone have any advice on the best way to take off the grenade launcher sights then? Any help would be greatly appreciated.
