a first wing section and a second wing section extending distally from respective opposite sides of the upper adaptor section and configured to extend over the firearm rail when the adapter is mounted on the firearm rail;

a first foot section supported by the first wing section, a second foot section supported by the second wing section, wherein the first foot section and first wing section form a first groove and the second foot section and second wing section form a second groove, the first and second grooves configured to receive the firearm rail to mount the adaptor to the firearm rail;

wherein the adapter comprises flexible material configured to permit the first foot section and the second foot section to snap the adaptor onto the firearm rail with the firearm rail received in the grooves;

the upper adapter section having a top surface and at least one riser projecting upwardly from the top surface, the riser having an opening;

a fastener sized and shaped to be received through the opening in the riser to connect an accessory to the upper adapter section.

2. The system of claim 1 , wherein the adapter further comprises a taper on the first foot section, the taper being positioned to engage a firearm accessory when secured to the adaptor by the fastener.

3. The system of claim 2 , wherein the taper is shaped and arranged on the adapter to drive the first foot section toward the section foot section upon securement of the firearm accessory to the adaptor by the fastener to further secure the adaptor to the firearm rail when mounted.
