if your looking for a gun that you can upgrade/ downgrade easier, i would go with the classic army. but if your looking for an outdoor gun go with the echo 1. it is ready for outdoor right out of the box and it comes with a 450 highcap mag and 100 midcap mag if you buy from Shortyusa.com
The G&G Combat Machine M4 is the best
It all depends of the company making it. A Tokyo Marui M1A1 Thompson would be better than a cheap Wal-Mart M4. But a Classic Army M4 would be better than a CYMA M1A1 Thompson.
Atlanta
yes they are but it looks better with p-mags
All airsoft can jam. Phrase your question better. Such as Does blowback airsoft jam more than spring airsoft?
Airsoft gi is a lot better. There website is way better, and there store is like 3 or 4 times bigger.
No
M41 is not a standard airsoft model, did you mean a different one. Also it depends who makes them.
Yes. All you need to do is take disassemble your airsoft, take out the spring, and buy a newer, better one. I reccomend all airsoft at Evike.com.
As a general rule, you get what you pay for.
The M4 CARBINE IS BETTER THAN THE M16.
The best method is to take it back to where you bought it and buy a better one. I have one, and it is a real piece of crap!
