There really isn't a best airsoft "m14". Your question is very vague, but i will try to answer it as best as possible. If you are looking for the most affordable m14, i would try to look at the cyma's, but remember, they are complete crap for an airsoft gun. i would suggest you look at higher grade models such as g&g or tokyo marui. if you decide to choose tokyo marui, remember that it IS expensive, but it will be the best base gun for upgrading and tampering. if you are looking for a good starter gun, i would suggest the g&g over the tm simply because of the practicality and that it is ready to play out-of-the-box and doesn't require any modifications to make it perform post standard.
It depends on where you're purchasing it from. Airsplat.com is the place that I'd go. I know they have great reliable gun for the best prices on the web and I purchase all my items from there and haven't had a problem.
The kart m14 is a really reliable gun. It's extremely accurate and has a good rate of fire, but the weight is one of its down falls.
The Airsoft M14 is a type of rifle. This rifle is electric, and is a type of sniper rifle. This gun can be used for many things, such as hunting and target shooting.

Now.. First of all this is a website ok?.. ok. Go to Evike.com to get tons of m14's but evike.com has more than 100,000 airsoft guns and they might be a little expensive, but they are the best quality airsoft.
Its depends on the brand. Many different companies make a M14.
