Magpul's MOE Enhanced Polymer Trigger Guard for AR-15 Style Firearms is a simple, drop-in replacement of the standard AR-15 platform. The trigger guard is simply installed utilizing 3 set screws, making it a very easy install on a new build. No more roll pin, hammer, and punch to install. This greatly reduces damage to the lower receiver tangs, especially when dealing with slightly out-of-spec receivers. Most are familiar with the popularity of the Magpul MOE's ergonomic design, and its ability to better accommodate shooters with gloves. The MOE Enhanced guard also cleanly fills that gap underneath the rear of the guard that can eat away at your middle finger.
