Abstract
Improved rail adapter systems which enable firearms, including M16 type rifles and carbines, without any changes to the weapon except the handguard, to support accessory devices effectively even under combat conditions are provided via the invention by modification of the top semicylinderical part of the rifle's handguard attachment to include an elongated leaf spring arrangement in the front end and a unique rear clamp arrangement at the back end thereof so the leaf spring and rear clamp combination operate to compensate for thermal dimensional changes and combat abuse problems to maintain proper alignment of accessory devices attached to the weapon.
