ATI MILSPORT AR-15 | 5.56 NATO | 16in | 60+1

The American Tactical / ATI MILSPORT AR-15 is a semi-automatic rifle built with metal-reinforced polymer upper and lower receivers to reduce weight while retaining durability. It is chambered in .223 REM/5.56 NATO and features a 16" barrel with a 1-in-8" twist rate. The rifle has a 15" free-floated M-LOK rail and an M4-style adjustable stock; the flat-top receiver is optic-ready. For an optic under $1,000 that pairs well with this platform, consider the Vortex Crossfire II 1-4×24 low-power variable optic for close-to-mid-range target work.

Typical uses for this configuration include range training and 3-Gun style competition, as well as varmint or small-game field use where a lightweight, modular AR platform is preferred.
