Well, it's has the stock KWA barrel in it and the mad bull 120 spring and Davids Chrono had me at 460. That M4 comes with a short 100 spring, it had leveled out at 365 with it. I have the Mad bull 100 and a 6.01 barrel going into it, hopefully that gets me closer to 400....with 0.20 grams. I am using Grim Racer speed grease on the gear box and the air seal on the piston cylinder is very nice, if I put my finger over the nub and push the piston, there is air lock and that my friends is nice!

So, change that spring and barrel...25 minutes later I got 390fps, I can live with that! Not sure on my chrono, does 33rps sound right with my 11.1 lipo? Everybody asks me how fast it shoots, never measured it before.

Host video on a website like youtube. Copy the url. Then click the button that has a pic of film on it. (says "video" when scrolling over it) when posting or replying in this forum. And paste url in window and click "ok" and bingo we have a winner.

Its only a 30 dollar question, I have an extra piston in stock, and I look forward to beating my record 25 minutes!!!!and to think, a month ago I didn't know a thing about the internals. I usually run 1of 2 7.4 Lipos, the 11.1 is just for eye brow raising giggles.

Its like a disease isnt it....what weight bb are you using @ 390 FPS? You should be using .28..

To determine what weight BB for a given FPS you should use this formula. The mass of the pellet equals two times the velocity, divided by 2,800 or M=(2V)/2800

Correct me if I am wrong, to play at BOA you have to be at 400 fps or lower with their bbs in their mags which are 0.20 gram. I can get 400fps with with 0.28 g with the 120 spring, but moves me to 470 at the 0.20 benchmark and would put my at an equipment advantage. I run 0.25 and 0.28 for more accuracy, I keep 0.20 on hand for testing purposes as I have my own chrono.
