Recoil in a gun means a kickback feel when a weapon shoots a bullet. This force pulls you a little backward, creating a realistic vibe for the shooters. AEGs have recoil but not as much as GBBs. After pulling a trigger, the player will experience a kickback which is not very powerful because of course, at the end of the day you’re not firing with a real gun. I always prefer AEG guns not pistols to feel the realistic force.
