The Tactical RIS Handguard is made out of aircraft-grade aluminum to be tough while staying light and to work with all types of barrels including Airsoft riles, RAP4 .43 caliber markers and real firearms. The handguard is all metal, and meant to take the beating of heavy recoil and rough handling. The Tactical RIS Handguard is compatible with all barrels and paintball markers, by coming with different size front and rear locking rings for different barrels. The Tactical RIS Handguard is also versatile: it can be used to attach all types of accessories, including flashlights, laser sights, tactical handles, optical sight mounts, and even grenade launchers.
