Picatinny Top Rail and Front Sight for Airsoft Tec-9

I designed this for my friend who loves airsoft guns and decided to share it with everyone. This picatinny rail and front sight system was designed for and installed on a KTC Tec-9. The front and rear sights of the airsoft gun need to be removed (unscrewed). The printed parts are mounted to the gun using the original screws from removing the original front and rear sights.
