How do you get a daisy 15xt bb air pistol unjammedk i have pellet stuck in chamber?

The 15XT is a BB pistol, like the name says. It is not a Pellet pistol. If you can't force is back into the BB holding slide then you might as well buy a new pistol. You will need a .177 caliber cleaning rod and use it to push the pellet back into the BB loading port
