I somehow managed to pour the exact number of BBs the magazine can hold (17) into my hand and let me tell you loading them isn't the most fun you can possibly have while playing an app. and since it's a double stack I of course messed up a bit but thankfully my Tool is able to move them into place. the blowback seems to work but I can't tell if I've pressurized it enough. it's cold outside too which, uh, isn't exactly ideal. but whatever. I've got some cans and everything I'll need in my backpack and I'll make some tea in a thermos or something. it's gonna be Great
