Airsoft M14 Rail Mount

I made a rail mount for a airsoft M14. The first rail mount file is the early blocky one. The second one I refined the design a little. The third one is basically the same as the second but with out the bar in the middle. The small mount is the small rail that only mounts the to the middle slide part. I tested it on a CYMA M14 AEG, not sure if it's compatible with other airsoft M14 brands. I think I used a short 10x32 alan head screw to secure the mount. The print settings are, 0.3 mm layer height, 4 shells, 10% infill with supports enabled.
