The Aero Precision MOD 4 Handguard (brand part number APRA600006C) blends robust construction with an ergonomic form factor, machined from 6061-T6 aluminum with an engineering focus on stiffness to drastically reduce deflection under load. The MOD, or Minimal Optical Deflection, design attaches to the upper receiver via a steel barrel nut, which also helps significantly reduce point-of-impact shift when running an infrared laser aiming device under load, a real consideration for duty and night-vision-capable builds.
