Like every gun-slinging joe, you too want an AR chambered in 5.56. An AR build with Aero Precision 16” upper will fulfill all your hunting, close-quarter combat, home defense, and target practice exigencies.

Precision and Quality with Affordability

5.56 already has a lower recoil compared to bigger rounds; the mid-length gas tube and low-profile gas block add to better gas dissipation and lower recoil. The M4 feed ramps aid in a reliable chambering of the rounds, and impeccable engineering gives your perfect shots every time.

The barrel is QPQ coated and made of CMV steel. On top of that, it is High-Pressure tested and Magnetic Particle Inspected after firing a higher pressure 5.56 round to ensure quality.
