How To Build An Ar15 Lower Receiver

Hey there, DIY Hero! Let's Build an AR-15 Lower Receiver!

Alright, listen up! Today, we're rolling up our sleeves and diving into the exciting world of AR-15 building. Specifically, we're gonna tackle the lower receiver, the heart of your rifle. Don't worry, it's not as scary as it sounds. In fact, it's a blast!

First things first, safety first! Make sure you're in a safe, well-lit space, and always keep your firearm unloaded while working on it. Now, let's gather our tools and parts.

Tools You'll Need:

• AR-15 Lower Receiver Parts Kit
• AR-15 Lower Receiver Vice Block
• AR-15 Armorer's Wrench
• Hammer
• Punch
• Screwdriver Set
• Oil

Got everything? Great! Now, let's start with the lower receiver. This is the serialized part of your AR-15, and it's the only part you need to register with the ATF. Most people start with an 80% lower receiver, which is essentially a blank slate. It's not considered a firearm until you complete it, so it's a fun, legal way to get started.

First, we need to punch the pin holes. This is where you'll install the buffer tube and trigger pin. Grab your punch and hammer, and carefully punch the holes in the marked spots. Be gentle, we don't want to damage the receiver.

Next up, we're gonna install the trigger pack. This includes the trigger, hammer, disconnector, and other small parts. It's a bit like putting together a tiny puzzle, but don't worry, it's not as tricky as it looks. Just follow the instructions in your parts kit, and you'll be golden.

Now, let's install the safety selector. This is the little lever that lets you switch between safe, semi-auto, and (if you're feeling fancy) fully auto. Line up the holes, insert the roll pin, and tap it in gently with your hammer.

Alright, we're cookin' now! Next, we're gonna install the bolt catch and release. These are the parts that let you lock the bolt back and release it. They're a bit fiddly, but with a little patience, you'll get them in no time.

Almost there! Now, let's install the takedown and pivot pins. These are the pins that hold the upper and lower receivers together. They're big, so they're hard to miss. Just line up the holes, insert the pins, and tap them in gently.

Last but not least, we're gonna install the buffer tube and buffer. This is where the buffer spring and buffer live. They're what give your AR-15 its distinctive "ping" sound when you fire it. Just line up the holes, insert the buffer tube, and tap it in gently.
