When I first started Airsoft, none of my friends played it. The result being I didn't know what was good, what wasn't. It pretty much sucked. I went through about 7 or 8 guns before I found a good gun, (I should really say reliable) and that is about the same time all of my friends started playing. And guess what!? They got to learn from MY mistakes. Anyway, I don't anyone else to go through that, so I am making a guide to help you get a jump start.
Step 1: Your Gun
Your gun is the quintessential part of all your gear. It is what helps you get kills, while helping you not get killed. Now I personally am partial to M4A1's And M16's, but those are definitely not the only guns out there. It all comes down to what your personal preference. Good brands include G&G, Classic Army, KWA, (I recommend the CQR) Magpul, and Javelin. (Magpuls are pricey though)
GUN ATTACHMENTS AND ADDONS
I recommend red dot sights, holographics, and ACOGs for longer range guns.
I recommend vertical fore-grips.
I do not recommend under barrel grenade launchers or any like things.
