I'm modding a 4B for my clan's use and I'm having trouble getting it to fire only one dart out of the hopper. The first barrel I put on it was 14" cpvc and since it didn't work I figured that it has so much excess air that it was scooping up another dart because the barrel was too short. After that I bumped it all the way up to 22" cpvc barrel and it's still a problem except now instead of shooting doubles it's shooting doubles and triples. Has anyone else had this problem and can help?

Can you share a piccy or drawing of your hopper construction, illustrating what is happening inside the hopper where the darts feed.

Definitely sounds like the length of your darts. I use airguns almost exclusively, and my stefans are never shorter than 1 1/4 inches. Anything less will probably cause doublefeeds.

Thanks Gears that seemed to be a problem, my darts are pretty short. However I just figured out a solution and added a few inches of 1/2" pvc before the hopper to slow down the air expansion before it gets to the dart.

Thanks for the feedback guys!

I know that you said you fixed it but I have a big blast and when I use a brithopp I dont get double feeds when I compare with a traditional hopper.
