It means it's not powered by electric or CO2 if it is spring powered you have to cock it after each shot
It is a source of power airsoft guns can run on. There are different power sources for most guns, such as spring, electric and gas. There are many different types of gas such as co2, propane, and green gas.
There is a 40 dollar silver 1911 on airsplat if that is what you would mean by bright
if u mean .43 gram yes you can, but for a pistol you don't need that heavy a round at most you would need a .30g bb.
I don't know what you mean by ajusted, but the power of it can definitely not be adjusted (in any airsoft pistol I have ever heard of) unless you buy new parts for higher gas flow, and the hop-up probably can't (if I am looking at the same gun you are). The sights also cannot be adjusted, if that is what you meant (again, if I am looking at the same one you are).
You mean you want a superb fps? In AEG, you can change the spring to the hardest spring you can have (i.e. M160 or M170). You should have a reinforced gearbox, metal piston & piston head, stainless cylinder, change the gears inside your gearbox to a reinforced one, have a high powered motor, and a good LiPo battery. In GBB, you can have a stronger gas (black gas or red gas). It means you should have metal slide and metal outer barrel. Oh yeah, you should have at least 0.28 or 0.3 gr BBs. Btw, you want to PLAY airsoft or you want to HURT somebody with it? Remember, play safe and fun is our purpose in playing airsoft.
Define real? If you mean like a actual gun which shoots bullets, no. If you mean real as in not fiction, yes. There are several CO2 powered rifles, such as the Beretta CX-4 Storm which is powered by a 88 gram CO2 cartridge.
