Agreed, it's probably the darts. There's an inherent problem with the Smart Air Restrictor as well. The prongs on the AR are spring loaded. They have a tendency to push the dart out of the barrel. If there's a pinhole leak in the AR seal, that will also have a tendency to push the dart forward when the prior chamber is fired. Both of these are design flaws with the Smart AR.

Here's a couple suggestions. You can try the "dryer trick" - throw your darts in a pillow case and run them for 10 minutes on high heat. This tends to expand the foam a little which makes the darts fit more snugly.

You could also dunk your darts in boiling water. Boil some water on the stove, then take a pair of kitchen tongs, grab the dart by the head, and hold the foam body under the boiling water for 5 seconds. (Young kids may need supervision)  This also expands the foam, making them fit much tighter.

Lastly, you could try coating the barrel. You'll need to borrow some of your sister's/mom's clear nail polish. Using the built-in brush carefully coat the inside of each barrel with a thin coat of polish. Reach as far down as the brush will allow, without hitting the bottom. It doesn't matter if you get a little on the dart post, but you don't want to glue the AR closed. So just coat the top 2/3rdsof the barrel as smooth as possible. This will make the barrel a few hundredths of an inch smaller, and the darts will fit tighter.

Good luck !
