Walmart crapsoft isn't airsoft.
The guns aren't even in the same universe for quality and effectiveness. You say your M16 works good? No, it doesn't. Not compared to a real airsoft gun. Most walmart crapsoft would probably break if it was shot by real airsoft guns.
As bravo one-six summed it up once, we diss clearsoft because the majority of people in airsoft do it to collect and skirmish with realistic looking imitation firearms. If you want airsoft guns to game with, you don't want walmart ones. If you want airsoft guns because they look cool, you don't want walmart ones.
