I live in a block of flats and we have one very large Backyard that's secluded from public view, only people staying in these flats can view it through their back windows. I don't own the property Just renting it out. The backyard is always empty as no really uses it and the shooting targets would be set up in the middle so it'll be highly unlikely for anyone to get hit or bbs getting ricochet towards windows. One thing I'm scared of is someone seeing my RIF and calling the police thinking its a real firearm, I'm thinking of two toning one of my rifles just for this.
