I have the same barrel length as you allizard, my M4A1 is 363mm, my KM4S with 407mm and planning to put 509mm on the KM16. I have the cheaper JBU TB's though  :( I don't know how they compare in performance and accuracy with the more expensive Prometheus but I can say that they do better than the stock barrels. But hey, they're half the cost of Prometheus barrels.  :D

Yeah... M4S is about 1" longer than regular M4.  But 363mm still work.  On the other hand, 509mm for M4 is way to long, unless you put a Barrel Extension aka mock silencer.   Here is US foamed sound suppressor/silencer is technically illegal to own.  Airsoft or not.  

Anyway, we are getting off topic.  And to reply Sputnik's post.  Most of us don't have trigger post issue.  I personally have 8 KWA AEG's that I assigned to my airsoft team locally for long term study.  Each gun ran at least 50k and done of our shell have any trigger post breakage.  That said, we do receive very few reports on trigger post breaking so we are still looking into this matters.

I think the sticky trigger comes from the sector gear on kwa guns. There is a point as it rotates that kind of puts it in the firing postition. I can't really explain it, but i think it's so that you get a more consistent shot and the gears make a full rotation. Allizard maybe you know what I'm talking about.Theres like a little piece  put into the sector gear and it makes contact with something on the gearbox.

It's call a sector clip... it's function is to allow the tappet plate pull back the nozzle a little bit longer to ensure proper BBs feeding into the hopup chamber.  It's essential for high rof setup.

So what people are saying is that the sector clip is touching the tappet and the spring on the tappet is whats creating the "sticky" trigger? I dont have this issue with my M4 :/

No I am not talking about the sector clip. There is alittle thing that sticks out on the bottom of the secter gear less than 1mm. I thought that this was the cause of this sticky trigger, but it is possible that it is the sector clip that's causing the sticky trigger though.
