^_^ of course!!
seriously though, best way to test something is to put in the hands of users that are known to break bits... i know of a guy here in calgary who's got a broken part 27, and he didn't even break a hinge plate first...
and not to be contrary or anything.... but are you sure you have an open bolt scar? the CO2 version changed the valve design from 3 post to 4 post, but the system stayed the same... still had a brass tube... if there's a brass tube inside the ejection port when you lock the bolt carrier back, it's closed bolt...

Im still looking for other areas to improve, drawings are almost done tho, so next week should start programming for toolpaths and hopefully round wednesday or so ill be making prototypes.

I don't really think you need to reinforce any dimensions on the part, just the material is really all that's needed.
