Assembling an AR-15 lower is not particularly difficult, but there are a few things you need to know before you start. First, make sure you have all the necessary parts. The most important part of the lower is the Lower Receiver, which includes the Trigger Group. You will also need a Buttstock (with Buffer Tube and Stock), Pistol Grip, Front and Rear Triggers, Barrel, and handguard.
Note that some of these parts may be already assembled onyour lowerr receiver. For example, manylowers come with a pre-installedButtstock and Buffer Tube. In addition, some triggers come asa uunits(Front and Rear Triggers), while others must be installed separately.

There are a few different methods for assembling an AR-15 lower receiver, but the most common and easiest method is to use a jig. Using a jig makes it easy to ensure that all of the critical dimensions are correct, and it helps to guide you through the process so that you don’t make any mistakes.
To start, you’ll need to gather all of the components for your lower receiver. This includes the lower receiver itself, as well as the trigger assembly, buffer assembly, and stock assembly. You’ll also need some basic tools, like a drill and an adjustable wrench.
Once you have all of your parts and tools assembled, take a look atyour lowerr receiver and identify all of the major components. These include the trigger well, buffer tube, and stock mounting points. You’ll also need to drill a hole for the pistol grip screw.
Next, you’ll need to install the trigger assembly into the lower receiver. Start by inserting the trigger pin into the lower receiver from the right side. Then, insert the trigger assembly into the receiver and align the trigger pin with the hole in the receiver. Use a punch or similar tool to drive the trigger pin through the hole in the receiver until it is flush with the left side of the receiver.
With the trigger assembly installed, you can now install the buffer assembly. Start by threading the buffer tube into the lower receiver from the left side. Then, insert the buffer assembly into the buffer tube and align the holes. Use a pin or similar tool to drive the retaining pin through the holes in the receiver and buffer assembly until it is flush with the right side of the receiver.
You can now install the stock assembly onto the lower receiver. Start by threading the stock mounting screw into the lower receiver from the right side. Then, insert the stock assembly into the receiver and align the hole in the stock with the hole in the receiver. Use a pin or similar tool to drive the retaining pin through the holes in the receiver and stock assembly until it is flush with the left side of the receiver.
Your AR-15 lower receiver is now assembled!
The AR-15 lower receiver is the part of the rifle that houses the trigger and other moving parts, and it is also where you attach the stock. Assembling a lower receiver is not as difficult as it may seem, but there are a few things to keep in mind. Here are some tips on how to assemble an AR-15 lower receiver:
- Start by removing any burrs or sharp edges from the receiver with a file or deburring tool. This will ensure that all of the parts fit together smoothly and prevent any damage to your fingers or tooling when assembling the lower.
- Next, instalthe magazinene catch springand magazine catch into their respective positions in the receiver. Make sure that the Magazine Catch Spring is properly seated in the groove in the receiver, and that the catch is flush with the surface of the receiver.
- Now it’s time to install the Bolt Catch Springand Bolt Catchinto the receiver. Again, make sure that all parts are properly seated and aligned before moving on to the next step.
- The next step is to install the Safety Selector Leverand Safety Selector Detentinto the receiver. Start by inserting the selector lever into the receiver from the right side, and then rotate it clockwise until it is flush with the left side of the receiver. Next, insert the detent into the hole in the receiver and push it down with a small punch or tool until it is flush with the surface of the receiver.
- The final step is to install the Pistol Grip Screwand Pistol Gripinto the receiver. First, insert the screw into the hole in the bottom of the receiver and then thread it into the grip. Next, push the grip onto the receiver until it is seated against the stop pin. Finally, tighten the screw down until the grip is secure.
With these tips in mind, assembling an AR-15 lower receiver is a relatively simple task that can be completed in just a few minutes. However, it is always a good idea to consult with a qualified gunsmith or armorer if you have any questions or concerns about your receiver or any other part of your rifle.
- To begin, clamp your lower receiver into the vice. You want to make sure that it is secure, but not so tight that you risk damaging the receiver.
- Next, install the trigger guard into the receiver. Start by inserting the front portion of the trigger guard into the receiver. Then, rotate the guard up into place and secure it with the roll pin.
- With the trigger guard in place, you can now install the rest of the lower parts kit. This includes the trigger, trigger spring, disconnector, disconnector spring, hammer, hammer spring, bolt catch, bolt catch plunger, bolt catch spring, magazine release, and magazine release button. Start by inserting each piece into its respective place in the receiver.
- Once all of the lower parts are in place, you can now move on to installing the stock. First, remove the buffer tube from the stock. Then, insert the buffer tube into the receiver and thread it in until it is tight. Next, reattach the stock to the buffer tube.
- Finally, install the magazine release spring and button. Insert the spring into the receiver first, followed by the button. Once both are in place, you are finished assembling your AR-15 lower receiver.
