Its design ensures compatibility with all Mil-Spec fire control groups and even cassette style match triggers. The flared magwell is a thoughtful addition, making reloads under stress quicker and more efficient. Additionally, the receiver comes in two colors: classic black and flat dark earth, catering to different aesthetic preferences.

Key Features and Benefits

One of the standout features of the KP-15 is its built-in detents for the take down and pivot pins. This design choice enhances durability by eliminating the need for spring and detent holes.
