it appears that i have "misplaced" the little rubber spacer that is part of the hop up in a g3 series rifle, my question is if by not having this very small piece in what way would it affect the way the hop up works?

If you are talking about the very small cylinder of rubber (packing) that presses the rubber sleeve (bucking) that goes over the end of the barrel, then you won't get a hop effect, as that packing creates the hopup bump. Cut off a small piece of the inner tube to a Bic pen to replace it or use a bit of wire insulation.

yup that would be the piece i'm talking about and the wire insulator is a darn good idea!!!

I use 16 or 18 gague. I take out all the copper wire, works well. That or a piece of an O-ring. Some places charge 5 bucks for that small piece. Rip off :cussing:

So i finally got all my parts in the mail, got the gun toghther went to shoot it and the bbs wont go past the hop up bucking?? Could it be that the bucking is too small or maybe that its not shooting right? My gun is a g3 by jg and the bucking i got is a promethus hard type.

The Prometheus hard type is meant for guns shooting well over 400fps with .2g.

If your gun is 400fps with .2g or below that, then you should be using the soft type.

Well that defineatly explains why they just get lodged in there, I also have a question about cylinders and ports, since i do have a long barrell type aeg would you recommend me getting a cylinder with 2 or more ports or just sticking with a single?

Cylinders don't different amount of ports, the ports vary with their position on the cylinder. Some are towards the middle for smaller barrles, and some don't have any at all for longer barrels. You want the volume of the front of the cylinder to the first hole to match the volume of the barrel. So, in your case with a G3, you would want a cylinder with no holes.

If the bb's are obstructed by the hop up bucking, it is because you have the hop up set too high, or the small plastic cylinder nubbing is too big. Either can force the bucking to obstruct the bb's path. If your inner barrel is greater than 509mm or 550mm (depending on sources) then you need to have a non ported cylinder in the mechbox.

So a none ported cylinder is my best bet,sounds good. Are there any websites out there where i can find articles over barrel types,springs, and cylinders, i would like to read these over and learn what is best for different gun types.

Take with a grain of salt since individual results will vary because of manufacturing and part dimension variance.
