EDIT: Actually, after further testing, the issue remains, but with one interesting fact.
If there are no darts being fired, the gun will fire just fine in semi- and full-auto modes at 15-16v with SGNerf's upgrade kit. However, if I put in darts to fire, it will fire continuously until all darts are exhausted.
This is interesting, because it means that something about the way the darts chamber or the pressure on the bolt is what is causing this issue to occur. Any ideas on what might cause the gun to fire uncontrollably with darts, but work fine without?
Also notable is that most of the time it will fire all darts with one trigger pull, but occasionally it will stop. Something about the interaction with the dart itself is causing this.
EDIT 2: It appears that using Streamlines works fine, but using my own homemade slug darts with white LogHome foam (fits tighter than Streamlines) causes the issue to occur. I'm guessing maybe it has something to do with the bolt not being pushed forward all the way and somehow not triggering a "stop" switch? I don't really know, because the darts fire just fine with any dart type, but using thicker darts seems to make the blaster fire uncontrollably until all darts are exhausted. It's not a length issue, either, because my slug darts are shorter than Streamlines and therefore length shouldn't be an issue.
