in the scope its a slide on the top put the scope on the gun aligned with the hole in the gun and scope then pour bbs into the scope
No
In my experience with any guns, as long as the gun has a tactical rail, you can fit pretty much any scope on it. For example I put my high tech airsoft red dot sight on my cheap nerf gun. You can modify what the scope can fit on because there are allen wrench screws to adjust the width at the bottom on pretty much any scope unless its already attached to the gun.
Follow the instructions provided with the scope/mount. You need to make sure you have a scope with rings that will fit on a "Dovetail" scope base rail. They have 3 main bases; dovetail- mostly for air and pellet guns...some 22's also, Weaver style, and Piccatini rail systems.
you can put a scope on almost any gun, but why?
You mount it the same way you mount a scope. The rifle or gun must have an 11MM or Weaver mount on the barrel for the red dot to attach to.
put a silencer on it
You can put a folding stock on all airsoft guns.
Yes
yes but it is hard to put on and inacurate
Most airsoft guns have magazines that you put bbs into just like you put real bullets into a real gun's magazine
No, you will not be able to put the airsoft gun on a remote control plane and shoot remotely.
