It's a rifle that's got a lot of discussion around it -- particularly as an option for the Army's improved carbine competition, assuming they offer it in a gas-piston version.
But the CM901 is a pretty impressive weapon, pairing the latest in carbine refinements with the experience of Colt.
As you can see, it was a bit difficult to get the Colt guy to open up. But there might be some information in here that's new to Kit Up! readers.
FYI -- I did get to fire the CM901 in 308 and thought it shot pretty well...
