# **KF5 Monolithic Lower Receiver Redesign**

### **Overview**

This project is a redesign of the **KF5 lower receiver**, originally created by [@TheGatalog-PrintableFramesReceivers](https://odysee.com/@TheGatalog-PrintableFramesReceivers:9/KF5:a?r=7kjmRuumzbVizHpJPZferuo7Y3ex6ME5). The original design used A2 pistol grips, but this redesign converts it into a **monolithic design**, offering improved durability and a cleaner, more streamlined build. The redesign includes enhanced magwell walls, a reworked trigger guard, and two distinct styles, each with compatibility for both default and binary trigger groups.
