Ready to build out a lower, but wanting to minimize spare parts that might tempt you into yet another build? The Aero Precision M4E1 lower parts kit for builders is just what you're looking for. This MIL-SPEC parts kit contains all of the small parts you need to build an M4E1 lower receiver but drops the parts you were going to toss in your parts bin anyway in favor of aftermarket upgrades. The remaining components are built to proper MIL-SPEC quality for maximum reliability and compatibility.
This kit does not include a fire control group, allowing you to build out the rifle you want with the bare minimum of leftovers.
