Our Zelos/M60B Standard Magazine Models...
We designed the Zelos/M60B Big Air Standard Magazines for easy loading, smooth feeding and accuracy out of your rifle. The Big Air Zelos/M60B Standard mags can handle pellets and slugs up to 10.5mm/0.41"in length! That is in the 35gr range (22cal) depending on the brand of slugs! The mag slides easily into the magwell and is held in place with strong magnets.
