Hey guys, Never messed with air rifles. Got a one day only kind of deal and wondering what peoples thoughts are on a couple models and whether air rifles in general are a good idea/must have at all.

I do live in urban so not like I have backyard visitors to be popping. Outside of popping cans any real use to these? Can they actually legally be used for small game like rabbits or something or purely for squirrel annihilation?

Models I have access to :

Recon .177
Big Cat .22
Rocket .177
Big Cat 1200 .177
Silent Cat .177
