Use this clamping mount to add a 21mm Picatinny laser, bipod, or flashlight mount to the Crosman 2240 or Benjamin Marauder Pistol. It is 3d printed in the US in ABS plastic. It uses 2 Stainless Steel socket cap screws and nuts to securely clamp to the C02 tube. It is compatible with the stock 2240 with steel or plastic breech and with the Benjamin Marauder Pistol.
Note that the slot in the rail is not square. Very few accessories require the full slot of a 1913 Picatinny and may not be compatible with this rail.
