Nito from AP2020 Outdoors worked out the fix on Lancer 20-round magazines after weeks of failures to feed, and documented the whole process in his Greyhive video. The problem is geometry. The .17 Fireball has a significantly shorter overall length than 5.56 NATO or .223 Remington, so cartridges stacked in a standard AR-15 magazine sit forward of where the magazine was designed to hold them. As Nito puts it, \"sometimes you gotta think outside of the magazine.\" Two separate failure modes stack on top of each other — rounds creeping forward under recoil, and feed lips that don't catch the case at the right angle. I've been struggling with this .17 Fireball. I'm about ready to chuck this rifle, the cartridge, the magazines, the whole nine yards. But I think I gotta figure it out. Key Takeaways The .17 Fireball's shorter overall length lets stacked rounds slide forward in a standard AR-15 magazine until the bolt drives one into the feed ramp and jams.
