What bbs are you using? Have you tried a different magazine or turning the hop all the way off?

What was the last thing you did to it before it started to jam constantly?

[Hibernator]

What brand tight bore? Madbull barrels are skinnier than other brands, so a non-madbull barrel in a Madbull hop can be a very tight fit depending on the rubber. If it's a Madbull hop and barrel, then it's the hop rubber - try a Madbull rubber which should be a better fit for the barrel/hop combo!

Might be stupid but if you're hop is on too much that could be stopping it.
