his is Ambi-Selector model for WE GBBR AR Series.(ex. WE 888, M4A1, M16A1 etc.)

Now you can change firing mode easily with your hand holding gun even if you're left-handed.Also, as it's firmly fixed, it can be used for a long time without breakage.

It replaces whole body of original selector.

Don't worry of Selector being broken. - You've got STL from now on!

You can use Bolt stl file that I made.If you hope to change, You will need a bolt of the specifications below.
