Colt AR15A4 | 5.56 NATO | 20 in. Barrel | 30rd

The Colt AR15A4 is a full-size, semi-automatic modern sporting rifle built on Colt’s AR platform. It is chambered for 5.56×45 NATO (.223 Rem) and features a 20″ chrome-moly-vanadium government-profile barrel with a 1:7 twist, a fixed A2-style polymer stock, and a detachable carry-handle with adjustable sights. For optics, a durable low-power variable optic under $1,000 such as a 1-6x low-power scope (for example, Vortex’s 1-6x class) pairs well with the 20″ barrel for both accurate shot placement and quick target acquisition.

This rifle suits range-oriented precision shooting and sport/competition use, and is also appropriate for varmint or small-game field applications when legal in your jurisdiction.
