It ain't paintball (yet)

Looks to me to be bigger than airsoft pellets, smaller than paintballs even in the .50 cal. range.
I Tested the WE23-S MicroGun for 50m and Got SHOCKING Results!

But a lot of fun!

<edit> yeah, it's apparently airsoft.

Sort of in the same vein, also not paintball, but fun. These also came in .177 for riot control.

A Drozd Black Bird can do 33.33 BPS @ just under 1200fps 😉

It rips threw cartons of copper head .177’s

That mini gun is cool as hell!
