1.i got it from richards sporting goods It's still a stuffty quality gun
2. i use 6mm bbs That's the size of the bb not the weight, handicap. I will assume you have .12g since most stores don't sell .20g and heavier.
3. i didn't have enough money at the time You need to save up
First of all, you want to get a gun from
www.airsoftgi.comThat's a great airsoft site and you can't go wrong if you pay attention to the ratings.
Second, you will want to buy .20g bbs. These will fly much straighter and a lot easier to fell if you get hit in a battle.
Third, if you are fighting with other people, you will want an automatic (Preferably an AEG). You can get a decent one for $150 and I promise it will be more accurate and more powerful than anything your friends can manage to get.
Fourth, you need extra mags. Most automatics have about 30 rounds per magazine, and that stuff goes fast. Get at least 3 extras.
