CZ-527 American 6.5 Grendel magazines

[VASCAR2]

The Cz 6.5 Grendel isn’t the easiest mag to use but get easier to load after they wear in. You might take a wooden ruler or dowel rod and cycle the spring aggressively. When my mags were new I loaded them to capacity and let them set loaded. With use mine are easier to load but still function.
