The enhanced enlarged trigger guard for AR15 rifles from Magpul provides protection against accidental trigger pulls. Unlike the standard Mil-spec trigger guard, it is secured in the weapon with two pins and is therefore not foldable. It is fully compatible with a wide range of lower receiver parts from various manufacturers of AR15 parts and firearms, without the need for modification.
The aluminum enlarged trigger guard AR15/M4 Magpul® has a shape of an open "V" letter. Thanks to this design, it offers enough space for the finger while ensuring comfortable shooting in gloves. This eliminates perhaps the biggest drawback of the USGI trigger guard, which is the gap at the back of the USGI trigger guard where you might catch or pinch your finger.
