Product Description
The Aero Precision M4E1 Complete Lower Receiver helps you begin an AR-15 build project from the ground up using a top-quality component. This Mil-Spec lower includes a carbine buffer tube, buffer and spring, and because it does not include a stock you can choose exactly which stock you'd like and add it yourself. The lower is multi-caliber marked and makes the perfect foundation for 5.56 NATO, .223 Remington, .300 AAC Blackout and more.
