Benjamin Marauder .22 spring open single pellet feeder

thingiverse

This is a spring loaded pellet tray for my air gun that uses .22 10 shot Marauder rifle magazine. It's a proof of concept model, and I'll be making modifications as needed to iron out issues - but it works just fine, albeit rough around the edges. To make it work seamlessly, you'll need a small compression spring similar to those found in click type pens, no bigger than 5 mm in diameter and about 20-22 mm long. Additionally, an M3 x 4 screw will come in handy. Some gentle sanding should also do the trick to ensure the parts slide smoothly without any snagging issues - and I'll need to file down the screw slot slightly to get it just right. I've uploaded a video to YouTube to show you how it works: https://youtu.be/0SiXEwHVOc8. After some testing, I've revised the loader to eliminate the gap where the cocking post would get caught - and now it allows for easy pellet loading before manually pushing it in, which partially loads the pellet on its own.
