As previously threatened. Here's my WE G36C which, if it isn't old enough to quality for antique and historic license plates yet, has to be getting there.
I don't even remember the last time I used this. Imagine my surprise when I gassed it up and spritzed a little silicone into the action that it functioned flawlessly. None of my magazines appear to be leaking, either. I'm almost disappointed I didn't have to tinker with it.

I deference to the comment about the G36 magazines not fitting in M4/AR/M16 pouches, that is indeed so. But their claim to fame is that they're factory designed to be jungle clipped together like this. I have three of them, and stopped there back in the day only because gas rifle magazines are damn expensive. I imagine there is an upperbound limit to how many you can stick together before the weight becomes an issue, never mind the width.
The optic on there is just some generic 1x red/green reticle thing from Walmart. It was cheap enough that I don't have to particularly care if it gets shot or I whang it into a tree.

Yes, I do have an orange tip for it for if I take it anyplace. I have the black one on it for display, since it spends 99.99999% and counting of its time just hanging on the rack.
I have wanted one of these (the airsoft model) since I first learned about airsoft. There was one when I was in highschool that is fully customizable just like the real platform! So you can have the submachine gun, assault rifle, sniper rifle or LMG variants.
