Every once in a while, darts can get stuck in the barrel, magwell, mag, etc.
*If you feel a jam, stop firing immediately and clear the jam.*
1) Prime the blaster, pull out the mag, and inspect where the jam occurred.
You might see a dart folded in the barrel or stuck in the end of the barrel.
2) Remove any jammed darts.
If a dart is stuck in the barrel, you can try to clear the barrel by firing the blaster with the breech closed to shoot out the jammed darts out.
Failing that, finding something long and skinny to push the dart out the barrel works well.
Jams are generally rare if the blaster is being used properly or with darts that aren’t super jank.
