High Quality Content by WIKIPEDIA articles! Rail Interface System (RIS, sometimes also referred to as Rail Accessory Systems) are the primary method of attaching accessories to small firearms such as assault rifles and light machine guns. This is done primarily in militaries and by firearm enthusiasts to improve the usability of the weapon being accessorized quickly and efficiently without requiring the weapon operator to field-strip the weapon. Most quality RIS systems are built to the M1913 Picatinny standard, which was the first standard developed. There are different styles of RIS, depending on how much the operator will be accessorizing the weapon.

More advanced systems allow for numerous accessories to be mounted simultaneously and cost an average minimum of $200 USD and up for a decent quality system.
