Functions of Each Component in an AR 15 Lower Parts Kit
The AR 15 lower parts kit is a collection of components that are essential for the functioning of the lower receiver of an AR 15 rifle. Each component has a specific function, and together they ensure the smooth operation of the firearm. Let’s take a closer look at the functions of some of the key components in an AR 15 lower parts kit:
1. Trigger
The trigger is perhaps one of the most critical components in an AR 15 lower parts kit. When the trigger is pulled, it releases the hammer which strikes the firing pin, igniting the round and firing the rifle. The trigger has a sear that holds the hammer in place until the trigger is squeezed, allowing it to move forward and engage the hammer.
2. Hammer
The hammer is responsible for striking the firing pin, which in turn ignites the primer of the ammunition. It is held in place by the trigger sear and is released when the trigger is pulled. The hammer also resets after each shot and prepares for the next round to be fired.
3. Disconnect
The disconnect is a small component that plays a crucial role in the semi-automatic function of the AR 15 rifle. When the trigger is released, the disconnect engages the hammer and prevents it from engaging the firing pin, ensuring that the rifle does not fire in a fully automatic mode.
4. Magazine Release
The magazine release is the mechanism that allows the shooter to quickly and easily remove an empty magazine from the rifle and replace it with a fully loaded one. It is usually located on the side of the lower receiver and can be operated with the shooter’s thumb or finger.
5. Bolt Catch
The bolt catch is a component that holds the bolt carrier group in its rearward position after the last round has been fired. It allows for easy reloading by locking the bolt carrier group open, providing access to the chamber for inserting a new magazine.
The AR 15 lower parts kit consists of many more components, each with its own specific function. These include the safety selector, pistol grip, trigger guard, takedown pins, pivot pins, and more. Together, these components work harmoniously to ensure the reliable and accurate functioning of the AR 15 rifle.
How to Assemble an AR 15 Lower Parts Kit
Assembling an AR 15 lower parts kit is a crucial step in building your own AR 15 rifle. While it may seem intimidating at first, with the right tools and knowledge, anyone can successfully complete this task. In this guide, we will walk you through the process, step by step, to ensure that you have a functional and reliable firearm.
Step 1: Gather the necessary tools and parts
Before starting the assembly process, it’s important to have all the necessary tools and parts ready. You will need a workbench or sturdy table, a vise block or gunsmithing vice, punches, a hammer, needle nose pliers, a roll pin punch set, and oil or lubricant. Additionally, make sure you have your AR 15 lower receiver, lower parts kit, and a receiver extension (buffer tube) with a buffer and buffer spring.
Step 2: Install the magazine catch
Start by installing the magazine catch. Insert the catch into the receiver and push it all the way through until it protrudes from the other side. Secure it in place with the magazine catch spring and button. Make sure the catch moves freely and locks securely in place.
Step 3: Install the bolt catch
Next, install the bolt catch. Insert the bolt catch into the receiver and secure it in place using the roll pin. Use a roll pin punch and hammer to drive the pin all the way through until it is flush with the receiver. Check that the bolt catch moves smoothly and engages the bolt properly.
Step 4: Install the takedown and pivot pins
Now, it’s time to install the takedown and pivot pins. Insert the takedown pin from the left side of the receiver and secure it in place with the detent and spring. Repeat the same process for the pivot pin on the right side of the receiver. Make sure the pins move freely and snap into place securely.
Step 5: Install the trigger guard
Install the trigger guard by aligning it with the receiver and pushing it into place. Use a punch and hammer to drive the roll pin through the guard and receiver until it is flush with the receiver. Verify that the trigger guard is securely attached and does not move or shift.
Step 6: Install the pistol grip
Attach the pistol grip by sliding it onto the receiver and aligning it with the grip mounting hole. Insert the grip screw and tighten it securely using a screwdriver. Make sure the grip is firmly attached and does not wiggle or rotate.
Step 7: Install the buffer tube, buffer, and buffer spring
Install the buffer tube by screwing it into the receiver extension (buffer tube) until it is tight. Slide the buffer spring and buffer into the buffer tube, making sure they fit properly. Test the buffer and spring by compressing them and ensuring they move freely.
Step 8: Final check and lubrication
Before completing the assembly, perform a final check of all the parts to ensure they are properly installed and functioning. Apply a moderate amount of oil or lubricant to all moving parts to ensure smooth operation.
By following these steps, you should have successfully assembled your AR 15 lower parts kit. Remember to always follow proper safety procedures and consult any additional resources or guides for specific instructions related to your particular lower parts kit.

Apply lubrication where necessary
During the installation process, it is crucial to apply lubrication to areas where metal parts come into contact with each other. This helps reduce friction and ensures smoother operation. Pay specific attention to the trigger and hammer pins, as well as any other pivot points. Using an appropriate firearm lubricant, apply a small amount to these areas to ensure optimal performance.
Take your time and double-check
When installing an AR 15 lower parts kit, patience is key. Take your time to carefully place each component in its correct position and use the appropriate tools to secure them in place. It is crucial to double-check each step along the way to ensure everything is correctly installed and properly functioning. Rushing through the process can lead to mistakes and may compromise the performance and safety of the firearm.
By following these tips and tricks, you can confidently install an AR 15 lower parts kit and enjoy the satisfaction of assembling your own firearm.
