Just checking - how confident are you that it’s the darts that are the issue? The Nexus Pro has a known manufacturing issue where the edges of the barrel at the breech end can be rough; sanding them smooth or running a blade around the inside of the barrel can fix that issue. Others have reported that the tightening rings are too tight and have had less jams once they sanded those slightly larger, although that’s harder to do without affecting the seal.
Magazine feeding is, in magfed blasters in general, also a common cause of jams: old mags, mags that were stored full, mags that are dirty inside . . . and, yes, also old darts with compressed foam (usually from being stored in a mag or front-loading blaster) are often to blame - though in the latter case it’s old/damaged darts that are the issue rather than darts that were shitty out of the box.
The Nexus Pro, like any sealed-breech blaster, will be happier with darts that have heads that are smaller (either slightly or much, but either way smaller) than the foam. Darts with heads the same size as the foam can work well in flywheelers, front-loaders, and traditional toy-style chamber-in-bolt blasters, so they’re fairly common.
So: if the problem is in fact the darts and if the conventional-for-a-good-reason solution of getting new darts of the right type isn’t the right solution for you, then old-school foam backer rod darts might be a good idea - but both of those are big "if"s.
