My first build questions. How to assemble AR15 lower parts?
There are a few things you’ll need to install an AR-15 lower parts kit. You’ll need a vise, screwdriver, hammer, and punches. The first step is to remove the pistol grip and the stock. To do this, use the screwdriver to remove the screws on the pistol grip and the stock. Once they’re removed, take the grip and stock off of the firearm.
The next step is to place the firearm in a vise. If you don’t have a vise, you can use some clamps. Once it’s in place, use a punch to drive out the pins that hold the lower receiver together. There are four pins in total – two on each side. Once they’re removed, the upper and lower receivers will come apart.
Now, it’s time to install the new parts. Take the trigger assembly and place it in the lower receiver. Then, put the disconnector and spring in place. Next, install the hammer and spring. Finally, put the selector switch in place.
Once all of the new parts are in place, it’s time to reassemble the lower receiver. First, put the upper and lower receivers back together. Then, replace the pins that hold them together. Finally, screw the pistol grip and stock back on.
Your AR-15 lower parts kit is now installed!
