Whats the Diff?

i was just reviewing some hacks, 3 different ones...
i see No recoil, and no spread together...
i wanted to know... what is the difference between them? is no recoil = reticule doesnt not enlarge...
no spread = bullets all shoot 1 place?

lol if you have both of then on the gun wont move any where only you move it

No recoil is when your gun doesn't move when you fire. No spread is where the reticule doesn't enlarge when you fire.
