The Recoil Technologies Mil-Spec Lower Parts Kit is a complete set of internal parts required for building an AR-15 lower receiver, designed to work with all Mil-Spec AR-15 lower receivers, and includes the vital functions of the fire control group (the trigger, safety selector, and detent, and the hammer), the bolt catch, magazine release, and the takedown pins. It is a reliable and affordable option for building a high-quality AR-15 lower receiver. Great for building out an AR-15 from scratch or for having it on hand as a replacement parts kit, this lower parts kit will prove invaluable to your arsenal.

The buffer tube is a simple yet vitally essential part of the AR-15 and AR-10/LR-308 systems. When installed on a lower receiver, this 6-position Aluminum Buffer Tube holds in it the buffer system of an AR platform rifle and also serves as the attachment point for the thousands of different style stocks that are out in the world.
