Sapol just declared gel blaster as regulated imitation firearm, which mean owner are require to have firearm licence to keep it or surrender to police if you don't.
owner are given 6 months of amnesty period to do or.
my question is, if i surrender my blaster to the police am i going to get registered in their database as an offender or any such?
The point of an amnesty is that you don't get recorded as an offender for handing it in.
However, if you're concerned, just destroy it yourself - it's just made of plastic. Smash it with a hammer and put it in the bin.
