I was not saying anything negative about Japanese airsoft.
I was asking if I should put it on my FAMAS because of my lower FPS

One Joule is equivalent to 328fps with 0.20g BBs. This is equivalent to 278fps with 0.28g BBs.
That's a very unfair statement to make. The barrel is of Japanese origin, and meant for Japanese domestic use where their guns are limited by law to 1 Joule or less. For guns that shoot within this limitation, this is one of the best barrels you can get. I personally use Twist barrels in all of my guns that shoot around 1Joule or below.
It is documented that going beyond 1 Joule will affect accuracy. My personal level of acceptance for degrading performance is at 350fps with 0.20g BBs. Beyond that, it's useless. Between 328fps and 350fps, you can see a degrading level of performance, but it's not so horrible that you still couldn't hit a target.
Still, the ideal limit is <1Joule.
