Overview
The KE Arms LLC KE-15 Billet Stripped Lower Receiver is designed for AR-15 builds, specifically accommodating the 5.56 NATO caliber. This stripped lower features a flared mag well, which enhances magazine insertion and ensures a smooth reload during operation. While this lower receiver is made from polymer and finished with hardcoat anodization for durability, it’s versatile enough to be used in various setups, but it's particularly popular in mid-length gas system builds.
