i just got a new cz 858 with a csa adapter. it is awesome. xcr mags feed every round and bolt locks without a hitch.
i wish the fit was a bit tighter. it feels like one hit and it would come apart. does anyone have experience with these? any ides how to tighten it up? i was maybe thinking of a shim or spacer.
