What is a P80 AR 15 Upper?

A P80 AR 15 upper is a complete assembly for an AR-15 rifle that includes the upper receiver, barrel, gas system, and handguard. The "P80" in the name refers to Polymer80 which manufactures parts for firearms including the popular Glock pistol and now they have made parts for rifles like the AR-15. It has gained popularity because it can be built at home by enthusiasts who want to customize their guns with personal touches.

The upper receiver houses important components of the firearm including bolt carrier group, charging handle and forward assist among others. Barrel length varies from one manufacturer to another but most often it measures between 16 inches -20 inches long or sometimes more depending upon local gun laws.

One advantage of using P80 components on your firearm is you can make adjustments such as customizing your own color scheme or ergonomics without having any restrictions since these are not considered firearms yet.

How do I install a P80 AR 15 Upper?

Installing a P80 Ar 15 Upper requires some level of technical skill that involves keen attention to detail when assembling all its different parts together onto an existing lower receiver into one functioning unit.

Before starting any work on your new build there are safety precautions you must take into consideration. Ensure that there are no rounds in your chamber before beginning any work as well as ensuring safety glasses should always be worn during installation processes especially if you're handling tools like hammers which could inadvertently cause harm.

Begin by installing all internal components such as bolt carrier group (BCG), charging handle and forward assist mechanism onto their respective locations within the assembled upper receiver then sliding down onto lower half while matching up trigger pins located inside both receivers until they align properly allowing them slide into place seamlessly once tightened down using provided hardware screws with proper torque settings so nothing moves around unpredictably post-installation.

Are There Any Legal Requirements for Building a P80 AR 15 Upper?

There are no legal restrictions on building your own firearm from scratch and this includes an AR-15 rifle. However, the process of building one may vary depending on which state you reside in. California has laws that have set limits to what parts can be used in a DIY build, requiring certain features such as bullet button tools rather than fixed magazines whereas other states do not have any regulations.

In order to avoid potential legal issues when building your own rifle it's highly recommended that you research local gun laws prior starting your build so as not run into complications down the line.

What Makes P80 AR 15 Uppers Different from Other Manufacturers?

P80 stands out among other manufacturers due to its use of polymer material which makes their products more lightweight than traditional aluminum upper receivers while still maintaining high levels of strength and durability. They also create unique designs for their upper receiver shapes that differ significantly from most industry standard models giving you more options for customization.

Another aspect is how they make modifications easier by having pre-drilled holes already located within the unit with screw threads making installing accessories or rails effortless compared to traditional uppers where modding may require drilling new holes or tapping metal parts into place.

Where Can I Buy a P80 AR 15 Upper?
