I wouldn't mind running a can on mine, although I don't know if that would incur additional stress on the gun and given the parts situation, I would rather not do that.
However, if I could get the stock brake off, I would at least try it occasionally, but that sucker is on there. My plan was to shoot out the original barrel and then have the replacement GM chopped. However, at the rate I am going, that could be the year 2030. After the first year, I shoot it much less than I expected. Still picked up a spare semi when I found a mint Howco for $3k out the door with an extra firing pin.
I like the stormwerks optics rail. I have an UBR on their with adapter, however would like to go with something folding. Uzitalk has an FNC dedicated forum and although not very active, still better than anywhere else.
