Here's the FPS info. The accuracy is improved too but I base that on someone else's not personal experience. I hope to do a test soon. :gun: (follow the link)

That's what I am shooting. Yours may very well be different. I started over 400FPS to begin with.:gun:

Yeah i also need pictures to see how to install, i don't want to waste 50 bucks to place it plus shipping to get it installed. I have little skill on taking off any airsoft gun, and little or no skill to put it back because it's and a**!

Installing a barrel really isn't that hard. Look up AirsoftGI's videos and I think you'll find one on that. Also, mechboxmechanic also made a video I believe on that subject. Just be careful, do some research, and don't force anything!

For the trigger, where does the spring end go? i don't understand what goes where when re-assembling the trigger. Does the spring hook onto something? how does it stay in place?

The trigger is a little tricky, the spring needs to be slipped into the trigger hole first, then the entire trigger needs to be pushed towards the front of the gun without rocking it to get the little tabs in the trigger into their slots.  The best way I can describe it is to push the trigger into the hole, and move the entire thing forward (under spring pressure)until it slips into place, then make sure the pivot hole is aligned.

I seem to have gotten it to work so far. lol. I love to tinker so come to expect something to not go my way at first. I installed the edgi tbb and will be taking it out tomorrow for a game and will be interested in how it chronos.

My first few attempts at reinstalling the trigger had  the spring plop out when ever I pulled the trigger. Now it's in there. hopefully it doesn't plop out at the game.

The videos were a great help and I notice the little tabs and stuff. Just didn't understand why the spring would stay.

seems like a bunch of voodoo and magic!

Hey tiger, i notice that your tight barrel is longer than i have. Is that the upgrade from the kwa or some place else? is your long barrel the reason you have higher fps besides the jet thing?
