Multiplayer First Person Shooter Kit

Is it easy to switch from hitscan to projectiles without doing a ton of custom work? I will want to use a mix of both, and I’ve noticed that kits set up for hitscan often are missing basic things like spread options when you try to use projectiles. Of course, these things can be coded in by the user, but the whole point of buying a kit is to save the user from doing extra work on basic features.
