The MOE (Magpul Original Equipment) 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 two 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. The Enhanced Trigger Guard has an ergonomic and enlarged design to accommodate use with gloves or when shooting in cold environments and fills the annoying gap at the rear of the standard trigger guard. Also works well with most 7.62x51 AR platforms"" but some custom fitting may be required. All mounting hardware included.
