It is an inexpensive gun that is very reliable. It doesn;t have many after-market parts, but the good thing is, it doesn't need much. A venturi bolt and I added a regulator and I get very constant velocity. Even with a cheap Pure Energy Reg I usually get +-3fps per shot now.
Very gas efficient. I use a remote and even with the line waste, I get about 1,200+ shots per 20 oz!
Easy to clean and low maintainance.
I have broken maybe 3 balls in it in about 10,000 rounds.
The Zero Gravity 2-piece barrel has great distance and is reasonably accurate.Far better then most barrels that come on guns.
When I got mine, there was a sear problem. (from the early 2000 batch) but ACI went like lightning to fix it and has worked flawlessly since!
The barrel has very small ports, and if you do break a ball you'll have to basically wash the barrel out to get it back to 100%%
The GS model has almost everything you need. Like I said, the Venturi bolt is nice, and adding a regulator just makes it even more consistent.
When you get one it may need some adjusting to get things just right, but once adjusted all you have to do is keep it clean!
I see a lot of similar priced guns on the field where I play (no names, I HATE flames) and they are falling apart on the field and blowing o-rings. It is very worth it!
I got mine for only about $217.
I just recommended the F-4 to a friend and 3 friends. I recomend it all the time.
