well, i have my new F4 and i really lik eit. very comfertble ect, but i have a problem in that sometimes it shoots in bursts instead of semi. 2,3, or even 4 shots. i dont know if this has happened to anyone else or if its just some crazy thing here.

i love the field stripability of it. i can have the bolt out in like 20 seconds or less.

also what do you do to your gun maintenence wise, where do you oil and how often. before every game or after ect.

any tips of the trade id be really apprecive.

thanks,
yukon

That can be due to servel things, what I suggest doing is trying off your grip, look at the Sear, see if it's wearn down or oily or dirty, if it's oily or dirty smiply clean it. You don't want lub there because it has to catch your striker, then catch the striker, see if the lip is wearn and if it's dirty blah blah blah...
You may want to give your F4 and lower chamber clean too, every once in a while it's a smart idea just make sure when you lub that you don't put to much else it will shoot all over your gun like on your sear and out the trigger frame. Those are what I'd catch for first...Good luck man (=

I had that exact same prob and all it was for me was the sear so like fogbow said check that out.

well, i cleaned out the enitre bottom chamber and am glad to say that it is now working greatly! :tup: i think another problem was that the velocity was so high, but now tis turned down.

1 last thing. what does the little screwey thing on the back of the aci venturi bolt do?

It adjust the flow, don't mess with it if it's working good (=

Actually, the "screwy thing" is just the back plate for the venturi bolt. This can be adjusted, but its not what ACI intended. The venturi bolt's adjuster is located through the larger center port in the face of the bolt. This adjuster controls airflow from the valve to the chamber, thereby adjusting recock force higher or lower. If your gun is working fine, then its probably best to leave it alone.
