Aero Precision M5 Lower Parts Kit W/Moe Sl Grip, No Fcg For Ar-308 Fde

The Aero Precision M5 Lower Parts Kit with MOE SL Grip in FDE gives you everything needed to complete an AR-308 lower receiver assembly—except the fire control group. This is the smart choice if you're planning to upgrade to a premium trigger or already have one on hand. Built around Aero's proven M5 platform for .308 Winchester and similar large-frame cartridges, this kit ships with genuine Magpul ergonomics and all the small parts that typically get lost or mixed up during a build.

Aero Precision engineered this lower parts kit specifically for the M5 system, so every pin, catch, and detent is sized and dimensioned to work together without guesswork. The included Magpul MOE SL Grip in FDE offers a comfortable, secure hold and matches the aesthetic of modern AR builds. Because the kit omits a fire control group (FCG), you avoid paying for a trigger group you don't want and have total control over the heart of your rifle's performance.

Whether you're assembling your first .308 rifle or upgrading an existing lower, this kit handles the tedious hardware and springs so you can focus on choosing the trigger that fits your shooting style—competition, hunting, or general range work. The FDE color pairs well with most modern furniture and keeps your build cohesive from the ground up.
