The MOE Enhanced Trigger Guard is a polymer drop-in replacement for the AR15 / M4 weapons platform. This upgraded trigger guard is easily installed without the use of specialized tools, using three set screws to secure it to the lower receiver. This eliminates the need to install a roll pin with a hammer and punch and greatly reduces the chance of any damage to the receiver due to improper installation or out-of-spec receivers.Specifications and Features: Manufacture# MAG1186 Polymer Works with Most Ar-15 Lowers and some AR-10 Lowers Color FDE
