Colt CR6920 M4 Carbine | 5.56 NATO | 16.1in | 30rd

The Colt CR6920 is a factory M4-style carbine built around a 16.1-inch chrome-lined barrel and a 1:7 twist rate, chambered for .223 Rem / 5.56 NATO. It ships with a 30-round Magpul PMAG, a 4-position collapsible polymer stock, and Magpul MBUS backup sights. This semi-automatic, flat-top rifle is configured for modular upgrades and routine range use. For an optic under $1,000 that pairs well with this platform, consider the Vortex Strike Eagle 1-6×24 for fast target acquisition and versatile engagement at typical service-rifle distances.

Typical applications include precision-oriented range training and varmint/target shooting where a lightweight, readily configurable AR-pattern rifle is appropriate.
