Crosman QR BB Magazine - Pull Handle and BB Door

thingiverse

Somehow, I received a QR mag purchased as new that had been dropped. The pull handle was barely holding on, and the BB door was completely missing. Here are the replacements. Pull Handle: When slicing, I add a two or three 4mm supports under the overhang on the bottom of the pull handle, just to prevent bridge sag. Also, the two holes for the retention pin should be cleaned out with a #42 drill bit. Its a snug fit, push it all the way on to the cocking piece, then pull it back out slowly Install the retention pin using a small vise or medium slip joint pliers. Slow, Steady, and keep the pin in alignment until fully seated. The pin is self retaining (one end is knurled). BB Door: The BB Door prints with no supports. It's a tight fit when first snapping it in, just wiggle left/right and push.
