This doesn’t answer my question, you’re deflecting, however it also accepts 10 or 20 round magazines just fine. Personally I would say I like the option, my preference is 20rds, it makes it a little easier when shooting from a resting position.

I don’t understand how cosmetics are relevant to its function. Like many other rifles, an AR-15 is usually semi-automatic, is that the issue you have with it?
