I think that guns made by echo 1 and other cheap guns are frowned upon, because the people who generally buy them are not interested in actual milsim play.
Not all of us frown upon them.
I recommend them to people who are interested in the Mil Sim aspect of our hobby all the time.
reason:
1. They are less expensive, thus allowing the person to spend more money on quality gear and such.
2. Out of the box these guns have better performance than most Maruis.
3. In reference to #1, the lower price on the gun allows money to purchase standard style mags, which is also important to the Mil Sim aspect.
No matter how you look at it our hobby is an expensive one to get the full Mil Sim feel to your gun and gear.
I'm not a fan of even TM because they don't come with metal bodies standard.
Metal bodies are not the be all and end all of airsoft.
I have a few of both. I like my plastic bodied giuns, because they are lighter and will generally feed well with almost any mag.
Also there are guns like the P90, and G36. These are not metal in the real world either.
Gunfighter please don't take this as a personal attack, I just quoted you because your answers are clear and intelligible.
Keep up the good work.
