That suppressor thing seems cool, Since it means that we can now see muzzle flashes from snipers without the suppressor.
Hopefully you need to trade the suppressor with something that actually matters so you need to sacrifice something valuable to get that extra bit of stealth.
Although i don't see too many uses for the armor piercing bullets, since things like ATVs don't really have any armor in front of the players driving,
they could be useful on humvees since the rounds shouldn't be so OP that they pierce even tanks.
I am not to sure why you would get flechette rounds since I thought they were illegal to use though. That might just be for hunting in Canada or something strange though since Canada doesn't want anyone to have any fun
