I believe I've heard of others having to make some modifications to the Bravo chassis to get the trigger hanger to fit. However, supposedly Impacts have made their newer trigger hangers with a smaller foot print, so these may be a non-issue these days. I'll let others with Impacts and Bravo's chime in to confirm.
If you haven't already purchased an Impact, the Lone Peak Fuzion + Bravo is a great combo. My wife's rifle is a Fuzion in a Bravo, and it's a pretty awesome setup. One thing to keep in mind is that the chassis itself is pretty light, and it's easy to make the system nose heavy if you put a heavier contour barrel on it. My wife's rifle has a 24" heavy palma, and it's definitely a bit nose heavy. I bought some heavy spacers from KRG to try and put the COG more rearward.
