You will need two M3 screws. The screws are not included, but can be easily sourced from your local hardware store (e.g. Home Depot, Lowes, etc.).
Airsoft equipment used for illustration of this Shotgun Barrel Picatinny Rails are not included.
WARNING: Although you can use this mount adapter to fasten your Picatinny accessories to your real firearm, this adapter has never been tested with real firearms before. We do not know if the firearm heat/recoil will or will not damage this mount and any of your accessories. Use it with real firearms at your own risk.
