Bummed to see these won’t work the the Curtis actions.
Any particular reason they won’t work? Just from glancing it looks like the Curtis strips rounds from the mag like any other push feed action.
Curtis has a bigger diameter bolt (no idea why they elected to do that). It's also a 3 lug vs 2 lug which can interfere somewhat with some mags. Mapgul polymer mags for example are a bit rough in my Curtis Axiom action, but works flawlessly with AI, MDT etc
