YHM is pleased to offer our 9mm Top End Kits. These kits include everything you need to convert your standard AR-15 type rifle to fire 9mm ammunition. Only the best products available have been selected for this kit. These top ends were designed and tested using a MIL-SPEC lower receiver with our 9mm Magazine Adapter and a Standard Hammer. Due to differences between manufacturers, we cannot guarantee they will work on every lower receiver.
