Hey i guess this is the part where i introduce myself, lol. I'm Dane and i got into airsoft when i got my first spring p22 from Canadian Tire lol. I saved and saved until i could by my M4A1 AEG, its a TM replica so it has its problems but its been upgraded so it still leaves quite the mark . Anyways, i was just looking for some suggestions on external upgrades for my gun cuz its stock on the outside. I dont even know where to get rails!! So by reading the other threads you guys are pretty pro and i was wondering if you could help out a poor noob
