After seeing the internals of this and all the plastic gears I'm starting to wonder how it will hold up with a spring replacement, it seems like there'd be too much a chance of stripping the gears over time or if you put the wrong type spring in.
I'm a lefty, do you have any idea if it is an ambidextrous/left handed magazine release button? The pics show its righty but I couldnt tell about a lefty.
The size of the Barrel Break doesnt look too bad, a little bigger with longer barrels than I was expecting. It sounds like it has a dual stage trigger for seperate barrel firing.
