Picatinny fixed sights

I made these sights for my airsoft replica of the G18C (but it should fit any picatinny rail) because I did not find any that I liked. It's easy to slide on the rail and it doesn't move after it's been installed.

I'm using Planetler's picatinny rail for G18C, you can find it here: https://www.thingiverse.com/thing:2481034
