There is no real BEST airsoft gun. It's really whatever suits your budget, and your taste in guns. It could be green/red gas, CO2, spring, or electric. Here are some good sites I have run into over the years:
www.airsoftgi.com
www.cobraairsoft.com (I don't know if this URL is right.
www.airsoftatlanta.com
Some sites I would NOT recommend:
www.airsplat.com
www.airguns.com
www.EVIKE.com
www.airsoftmegastore.com
Just some advice, hope it was helpful to you.
watch out though i got a $30 rifle that just broke when i was holding it...right before a big airsoft game so be sure to get the right gun and if its cheap try to have some extra $$$ to buy a new one...just incase.
THE BEST GUNS ARE PISTOLS:):):):):):):):):)!!!!!!!!!
Nerf gun
The best airsoft gun you could get for $150 would probably be an Aftermath gun, but you could get a JG M4 or M16 for under $150
The one you can afford
If you are just starting airsoft i would highly recommend an aeg, (airsoft electric gun) but if you are pro and experienced, a trained camouflaged sniper is the best, an invisible predator. However it does depend on the user of the gun. If you are asking performance wise then g&g makes the best airsoft guns on the market. (currently in the US)
I say twin ozez are the best cheap airsoft guns
dont get that gun walmart has the best beginer guns
www.shortyusa.com
Definitely Nerf.
it depends on what cheap is to you
The best way - go to near airsoft workshop, give them money and tell what do you want. If you decide to modify airsoft gun by yourself - be warned, this may ruin your gun and even be dangerous to your health.
"Systema" is by far the best airsoft gun brand out there.
