It depends if it has a electronic trigger and which board it has in it. If it's the stock version with out an electronic trigger, it proberly won't have 3 round burst. But see if you can find out if it has a electronic trigger and if that has the 3 round burst setting.

An Airsoft gun
It means that your airsoft gun can only fire one BB every time you pull the trigger (semi-auto). It's on the contrary to burst (fire three BBs in a single trigger pull) or full auto when you can fire a lot of BBs in a single trigger pull.
A pump airsoft gun is a gun that has to be pumped every time before shooting. Ex. Airsoft shotgun

A "Round" is usually how many shots are in the loading chamber. it can be one or many. A BB gun can carry 100 ROUNDS but only fires one ROUND at a time. A Machine gun fires many rounds in a "burst".
No
It is an airsoft gun based of the PPSH-41 gun
The 3 round burst gun from halo3.
All right, first of all, Hopup does not control the firing mode. That's determined by the selector switch. As the 3 round burst, they do not make guns like that, as the electrical current will have to be cut off to stop the gun from shooting a fourth, fifth round, etc. This is very difficult, because different internal parts, as well as battery size, power, all effect how long it takes the gun to fire 3 rounds. They do make a wiring set that runs between the gun and battery to cut off the electric current for a 3 round burst, but I don't think it's very reliable. Have fun with that.
