What do you think of this Hawke? Seems like a decent one!!

Vantage IR Riflescope 4-12X50 AO, 1", Mil Dot (Etched) https://www.amazon.com/dp/B00WR5U1Q4/ref=cm_sw_r_cp_api_i_5D4HVSGBBHYFR3F8JWAB

Gun Yes, Scope No, Pump Maybe, Pellets Yes. Shop around to get best deal. I would by an AO or a side focus scope. If the parallax on a scope is set at 100yds then that will be problem. With an Ao scope your parallax will be eliminated when you focus Scope orScope2 .I purchased a Hawke scope from Ebay in the UK was great deal.
