The Aero M5 AR10 Lower Parts Kit Minus FCG is designed for builders who want complete control over their AR-10/.308 build. Unlike a standard lower parts kit, this version excludes the fire control group (trigger and hammer), giving you the freedom to install your preferred aftermarket trigger while still including all the other small parts needed to complete your Aero M5 lower.

What Is the Aero M5 LPK Minus?

An AR10 LPK Minus is a lower parts kit that supplies the essential pins, springs, detents, selectors, and catches required to finish an AR-10 lower receiver but omits the fire control group. Shooters choose a Minus kit when they want to customize their rifle with premium drop-in triggers such as Geissele, CMC, or Timney, while still trusting Aero Precision quality for the rest of the build.

• Aero Precision Quality – Manufactured to strict tolerances for reliable fit and function.
