I think the ACOG is way better on there. It was already heavy with that medium weight SS barrel. I still wish I could have got pics when I test fired it with the Ti brake on it. That was pretty cool with the sparks. I don't know what it is about those Troy tubes that cause them to make your rifle look so long. I have the 11.0 on mine with a 12.5 barrel and it looks way longer then what it is until you pick it up and shoulder it.
