Our Zelos/M60B Slugr Magazine Models...
Leave it to Big Air Precision to innovate a new style of magazine! We designed the Big Air Zelos/M60B Slugr Magazines to handle nearly any heavyweight slug you can load in it. The Big Air 22 & 25cal Slugr mags can handle pellets and slugs up to 12.7mm/0.5" in length! That is in the 42gr range (22cal) depending on the brand of slugs! The Big Air Zelos/M60B 30cal can handle rounds up to 12.9mm/0.517, including Predator Polymag pellets! When you're done loading the Slugr mags, gently tap the mag on the bench to fully seat the slugs. That will assure they stay put until you chamber them. The mag slides easily into the magwell and is held in place with a strong magnet.
