Here is a detailed step by step video on how to install the lower parts kit and buffer/buttstock assembly for the AR15 and M4 platform rifles.
In this video, we are walking viewers through the process of assembling an AR-15 lower receiver, which involves several steps. Here's a breakdown of what you covered and key details:
**Parts Overview**:
You start by showing the **lower parts kit**, explaining each piece:
**Front and rear takedown pins**: One long (front) and one short (rear).
*Detent springs* and *detents* for the pins.
**Magazine release**: Button and spring.
**Bolt catch and release assembly**: Including the specific spring types.
**Trigger assembly**: With components like the hammer, hammer spring, trigger, trigger spring, disconnector, and related pins.
**Trigger guard**: If your receiver doesn’t have an integrated guard.
*Fire and safety selector* components: Detent and spring.
**Buffer tube assembly**: Buffer tube, plunger, spring, and associated pins.
*Pistol grip and screw* for securing it.
**Assembly Process**:
1. **Magazine Release**:
Begin by inserting the *magazine release assembly* (button, spring, detent) into the receiver.
Use a tool to help push the button into place and secure it with the threaded portion.
2. **Bolt Catch and Release**:
Insert the *bolt catch and release assembly* with its pin and spring.
Tip: Using electrical tape can prevent marring the receiver during installation.
3. **Trigger Assembly**:
Install the *trigger spring**, **disconnector spring**, and **disconnector* into the receiver.
Line up everything carefully and use a push pin to help hold components in place while securing the trigger pin.
4. **Hammer and Spring**:
Install the **hammer**, ensuring the hammer spring is positioned correctly to engage with the trigger assembly.
Do a function check to make sure the hammer locks and releases properly.
5. **Trigger Guard**:
Install the **trigger guard**, making sure the plunger pin is on the left side (as viewed from the back of the receiver), and it’s inserted properly to allow for easy operation.
6. **Pistol Grip and Safety Selector**:
Install the **fire and safety selector**: Ensure the hammer is in the locked position before inserting the selector.
Secure the *pistol grip* using the screw and ensure the safety selector functions correctly.
7. **Rear Takedown Pin and Buffer Assembly**:
Install the *rear takedown pin* and **buffer tube assembly**.
Use the *castle nut* to secure the buffer tube, ensuring the buffer tube is properly threaded and locked into place.
8. **Buffer Spring and Buttstock**:
Install the *buffer spring* and *buffer* into the buffer tube.
Attach the buttstock of your choice to complete the lower receiver assembly.
9. **Final Steps**:
Tighten all components securely, using tools like an *armorer's wrench* to tighten the castle nut and ensure proper function.
Perform a final *function check* on the trigger, safety selector, and hammer.
**Tips & Tools**:
Tools: Hammer, **AR-15 armorer’s wrench**, push pins, and possibly a special tool for disassembly pins.
Suggest using *blue Loctite* on the threads for the castle nut to keep things secure.
Emphasize doing a *function check* after each step to ensure everything operates smoothly.
