Aero Precision Epc Lower Parts Kit Minus Grip, Fcg & Trigger Guard Black

The Aero Precision EPC Lower Parts Kit (Minus Grip, FCG & Trigger Guard) gives you everything except the fire control group, pistol grip, and trigger guard—so you can customize those three critical components to your exact spec while getting all the other hardware you need to complete your EPC lower receiver build. If you're assembling an Aero EPC lower and already have a trigger, grip, and guard you want to use, this kit eliminates redundant parts and saves you money.

Aero's EPC (Enhanced Pistol Control) platform comes with proprietary parts pre-installed at the factory, but the remaining hardware follows standard AR15 compatibility. This lower parts kit includes all the springs, detents, pins, and controls needed to finish the job: takedown and pivot pins with their springs and detents, bolt catch assembly with spring and buffer, safety selector with spring and detent, buffer retainer components, and the threaded set screw for the takedown pin detent hole. It's straightforward, well-made, and designed to work seamlessly with EPC lower receivers.

Whether you're a first-time builder keeping costs down by reusing a quality trigger or an experienced shooter who already has premium fire control components on hand, this lower parts kit removes the guesswork. You get exactly what the EPC platform needs—nothing wasted, nothing missing—so you can focus your budget on the parts that matter most to your build.

Frequently Asked Questions

What's not included in this lower parts kit?

This kit omits the pistol grip, fire control group (trigger and hammer assembly), and trigger guard. You'll need to source those separately, which is ideal if you already have components you prefer or want to choose specific upgrades.

Will this kit work with standard AR15 lower receivers?

No—this kit is engineered specifically for Aero EPC lower receivers, which feature proprietary design elements. Standard AR15 lowers use different geometry and may not be compatible with all included parts.

What tools do I need to assemble the EPC lower with this kit?

We don't have tool requirements listed here, but lower assembly typically requires punches, a screwdriver, and basic armorer's tools. Check Aero's assembly guide for your EPC model for a complete tool list.

Does this kit include everything except the grip, trigger, and guard?

Yes—takedown pins, pivot pins, springs, detents, bolt catch assembly, safety selector assembly, buffer retainer components, and the threaded set screw for the takedown pin detent hole are all included. Everything else needed to finish your EPC lower is in the kit.
