Colt CR6940 Monolithic Carbine | 5.56/.223 | 16.1″ | 30rd

The Colt Monolithic Carbine CR6940 is a one-piece upper AR-style rifle chambered for .223 Remington / 5.56 NATO with a 16.1″ chrome-lined government profile barrel and a 1:7″ twist rate. Its monolithic upper provides a continuous Mil-Spec rail from the receiver to the front sight for repeatable optics mounting, and Magpul MBUS folding sights are included for iron-sight use. For an optic that pairs well without exceeding $1,000, consider a Vortex Strike Eagle 1-6×24, which fits the carbine’s intended use and rail geometry.

Applications: recreational target shooting and competitive carbine matches such as 3-Gun or service-rifle-style competition.
