All airsoft can jam. Phrase your question better. Such as Does blowback airsoft jam more than spring airsoft?
Varies by the pistol. Normaly better than spring.
No. even though some spring guns have great range, co2 allows you to fire more then once before reloading.
It all depends on the strength of the spring airsoft rifle. If your refering to pistols (I will assume you are), I prefer a co2 or green-gas pistol over a springer anyday. In the big picture, springers are regarded as cheap and useless. Although the fps may be better than that of the gas, it's range (and the fact that you need to cock spring guns after every shot,) it is usually better to save up your cash and buy a good gas pistol. However, even I need to admit that some springers (i.e. quality snipers {runs you about 90-110 American dollars}) are way better than their co2 and green-gas counterparts.
possibly in quality by a little but not in performance.
They are, unless the legos are made out of gold, than no.
I really thinks it depends on how often you use it, and if it is properly maintained. All depends on what you are willing to do to keep your airsoft nice and shiny. hope it helped
The M4 CARBINE IS BETTER THAN THE M16.
Not necessarily
most spring airsoft pistols cost about that... but if it's a used pistol than it should be about 10
There really is no answer to that question, because it is based on opinion and personal preference. An airsoft sniper rifle and an airsoft aeg are two different things, and since aegs can be full or semi auto, and sniper rifle are only bolt action or spring, there really is no comparison. Sniper rifles are more powerful, but aegs have a much higher rate of fire. It all depends on what you want to use and what you like better.
