Made this wall mount for a cheapo ar15 replica. It should work with most other ar15 AEG replica's though. GBB replica's might not quite fit, because of their valve knocker protruding into the mag well.
Designed to be mounted with four 4x40mm wood screws. I ran into issues with driving the screws all the way in on the top holes, as the drill's bit-holder was not long enough. I used a screw driver to get them in the last little bit.
If I get the chance to try it on a GBB, I will change the model accordingly.
Real steel should probably work also.
The author marked this model as their own original creation.
