If you are a gun enthusiast, you must have basic knowledge of building a gun from an 80 lowers. It’s legal in most parts of the United States, but it would be wise to check your local state laws. If you are interested, 80 lowers will help you build your very own firearm from your own home. Following are some things you will need to build a gun at your home.
“Frame kits” are now being sold by third-party firms, allowing anyone to construct pistols that can be interchanged using the same parts. An “80% frame” or “80% receiver” is a more colloquial term.
To put together everything, you need a few tools that are listed below:
- A vise,
- Flat-headed screwdriver
- A drilling machine
- Fine grit sand papers
- A Dremel
- Machine oil/ lubricant
For assembling, one must follow these steps:
Make sure the jig is level by securing the frame using a vice. Screw the jig’s ends if desired to minimize frame movement. Start sanding the polymer tabs designated for removal with the sanding drum attachment on the Dremel.
For the next step, you must drill the holes for the rear slide rails and the trigger assembly while the frame is still in the jig. You can see these holes’ exact location and size on the jig. This phase uses a hand drill with the supplied drill bits. Strike the whole frame from both sides when drilling. After doing so, apply WD-40 to a piece of coarse-grit sandpaper to get the wet-sand effect. Sand off and clean polymer remains stuck to the frame, very cautiously to avoid biting into it.
You may begin putting the frame together at this point. At the top of the frame goes the slide lock spring to install the lock. Push the slide lock into the frame channel above the spring after pressing the spring with a flathead screwdriver. The sliding lock’s tiny lip should be placed at the frame’s rear.
Now it’s time to assemble the magazine catch spring via the top of the frame into the groove at the front of the magwell. A screwdriver should be used to guide the spring of the magazine catch into the magazine release’s catch hole.
The sliding rails for the front and back of the frame should now be installed. To use the trigger assembly, place it in the back of the frame from the side. Now, drive in the trigger housing pin, the P80 front rail pin, and the locking block pin, respectively.
Pull out the sliding stop lever. A U-shaped spring rests under the locking block pin, and the hole lines up with the trigger pin hole. Set the trigger pin and attach the slide to the rails by lubricating them.
