Heavy Barrel RU shows his 3D Printed airsoft IZH-27 in this video... "Hello everyone! I present the project of the airsoft gun "IZH-27", using gas shells in the form factor of 12-gauge cartridges (Green Gas and APS CO2). This over-and-under differs from the project "Dizhlike" in that it has a simplified and more stable system of gas shell initiation. This project also implies the use of original wooden fittings from the IZH-27 (MR-27) gun of a new model."
