Airsoft 3d

This's my homemade airsoft, i spent a lot of time to create this object.
To create this project, you need to dedicate yourself and have creativity, some parts are not made with the printer so you have to create some pieces.
I used 3/4 inch and 1/2 inch pipes, a 6 mm threaded bar, a piece of leather, pen springs, an umbrella spring and a few screws. The barrel is a precision barrel for airsoft.
The sights is in another project of mine here on the thingiverse.
Good look!
