I used to be into guns insanely. Since real guns are illegal in Japan, I used to do guerillla warfare in the woods where there is a motorcross course in high school. I have a gas powered desert eagle, berreta, glock, M4A1, and a PSG1 which is a sniper rifle. Used to custom the hop (spring) so the bullet flies twice as far. We used to dress up in guerilla warfare outfits with eye masks, face masks, extra clips, batteries (for the M4A1), etc...
A whole lot of fun
Note: unlike the US, bb guns here dont come with the red cap.
