If you want to get your hands on a Colt CM901 in a more intimate environment than SHOT Show or AUSA then make sure you visit Colt at this week’s Soldier Equipment & Technology Expo & Conference at Fort Bragg.
The Colt CM901 can change calibers from 5.56mm up to and including 7.62 x 51mm NATO, by changing the upper receiver group at the user level. By simply disengaging the takedown and pivot pins, the user can quickly change from a 5.56mm Close Quarters Battle (CQB) to a full length 7.62 x 51mm Extended Range Carbine (ERC) configuration in seconds without the need to re-zero optics already mounted on the upper receiver assembly.
