Two Tone bb gun pistols can be bought by anyone with no license needed, unlike the black replicas we sell. There is no difference between the performance black guns or two tone guns as they are the same guns just in a bright color. There are basically 4 different types of bb gun pistols we sell the various types are spring, gas, co2 and electric powered guns. Spring pistols are usually the cheapest to buy and to run but the drawback is that you will have to manually cock the bb gun before each shot. Gas and electric battery powered bb guns are automatically reloaded and all you have to do is pull the trigger, and it fires, but you will have to buy green gas to make a gas gun work or co2 capsules if it's a co2 gun. (co2 is usually a little more powerful than gas and works better in cold weather) Lastly, electric guns either work with regular aaa or aa battery or the more costly ones come with rechargeable battery packs. All of our pistols are perfect for most situations, with the cheaper spring weaponry ideal for backyard battles or target shooting and the more expensive guns can also be used for target practice but can also be used airsoft skirmishing.
