Most guns with removable tips come with a standard reverse threading that accepts most muzzle accessories.
1/4th of the flash hider
If the flash hider is removable then you just screw it off and screw on a silencer. If the flash hider doesn't come off there is currently no good solution other than modifying both the flash hider and a silencer to attach and be secured on the gun.
The flash hider on the Barrett M99 airsoft can be changed, but unless you are using the gun for display only or movie production you want to make sure that the new tip does have the blaze orange that will comply with federal law. When using or transporting the gun without the blaze orange tip, any law enforcement agencies will treat you as if you are using a real steel model because they have no other way of telling the difference between the actual or airsoft models.

To build a complete airsoft gun from spare parts, you will need a lower receiver, upper receiver, grip, stock, fire selector switch, trigger assembly, magazine, magazine release, charging handle with spring assembly, complete gear box, motor, hop up unit, inner barrel with bucking, D ring, RIS/hand guard, outer barrel, flash hider, iron sights/optics (optional). This is a list for an intermediate level airsoft gun. If you intend to build a lower or higher quality gun, you will need less or more parts accordingly.
A used or broken gun that the company or maker has replaced any of the worn or broken parts. It should be cheaper but just as good as a normal airsoft gun
