Now that you’ve selected the small frame (AR-15) class and platform, and have selected the AR-15 rifle, its time to choose a finish level and buy your kit.

We have curated three finish levels for the AR-15 rifle:

- Enhanced Mil-Spec (E): This is the basic finish level and the starting point for the other levels. Everything meets the Mil-Spec, as applicable. This is a great starter gun and can be upgraded incrementally up to and beyond our highest finish level.
- Furniture and Controls (FC): This builds upon the Enhanced Mil-Spec finish level with improved interfaces with the weapon system and some targeted functional improvements. This finish level will work great for most people and should be the goal for upgrades to the Enhanced Mil-Spec AR.
- Duty and Competition (DC): This finish level offers the pinnacle of AR performance. In addition to the improvements of the Furniture and Controls finish level, the Duty and Competition finish level includes significant upgrades to the functioning systems of the AR. This finish level if designed for those who demand absolute performance and reliability.

Below, you will find the appropriate platform components to build an AR-15 rifle on the Aero Precision M4E1 platform. We have modeled this as closely as we can to the specs and quality of our PBA builds, without using any PBA components.

Please note that the component kits on the following pages assume that you are building on the Aero Precision M4E1 platform. If you are building on another AR-15 platform, you may need additional or different components.
