LS1 MP5 Housing, PA11

Our LS1 is a great entry point to the MP5 aftermarket world. It is our least expensive option but still maintains excellent durability and adaptability as a lightweight polymer material.  The nylon housing saves 3.2oz over the billet options. This is a furniture-less housing for MP5 trigger group.  It allows the user to utilize AR trigger, safety, and grip of their preference. Lightweight, ergonomic upgrade over original housing allowing for a much better trigger. Housing made from MJF PA11 Nylon. Ejector Lever and Pin machined from 4140 steel. All parts made in USA. Requires AR-15 Small-Pin Trigger set, AR-15 Safety Lever, and AR-15 Grip.  See our Sporting Trigger Group listings for complete assemblies. Compatibility Triggers Use AR triggers with full power hammer springs. The MP5 bolt carrier compresses the AR style hammer slightly more than an AR bolt carrier. Many two-stage triggers like Geisseles do not have the same range of motion, and are not compatible without modification. D
