The Ultimate Roundup of AR Build Kits for Enthusiasts

Introduction

Building your own AR build kit has become an increasingly popular pastime for firearms enthusiasts in the U.S., and for good reason. Here’s what you need to know right away:

• Overview: Customizing your AR-15, AR-9, or AR-10/LR-308 from the ground up lets you choose every part and feature to suit your needs.
• Importance: Building your own rifle can save money, improve your understanding of firearm mechanics, and ensure you get the exact components you want.
• Popularity: Thanks to the accessibility of quality build kits and the wealth of online resources, more people are taking on DIY AR builds than ever before.

Constructing an AR from a kit is more than just piecing together parts; it’s about creating a reliable, personalized firearm tailored to your specific needs and preferences. As the interest in quality build kits has skyrocketed, companies like Daytona Tactical provide enthusiasts with everything they need to build, minus the stripped lower receiver.

What is an AR Build Kit?

An AR build kit is a package that includes almost all the parts you need to build an AR-15, AR-9, or AR-10/LR-308 rifle from scratch. These kits are perfect for enthusiasts who want to customize their firearms and save money compared to buying a pre-assembled rifle.

Definition

An AR build kit typically provides all the necessary components except for the stripped lower receiver. The lower receiver is the part of the firearm that is regulated and must be purchased separately through a licensed dealer. The rest of the parts in the kit can be shipped directly to your door.

Components

Here’s what you usually get in an AR build kit:

• Upper Receiver: This comes pre-assembled and includes the barrel, handguard, and bolt carrier group (BCG).
• Lower Parts Kit: This contains all the small parts needed to complete the lower receiver, such as the trigger, hammer, and pins.
• Stock or Brace: Depending on whether you’re building a rifle or a pistol, this part provides stability and comfort.
• Buffer Tube Assembly: This includes the buffer, buffer spring, and tube necessary for the firearm’s recoil system.
• Gas System: This includes the gas block and gas tube, which are essential for the semi-automatic function of the rifle.
• Muzzle Device: This can be a flash hider, muzzle brake, or compensator to manage recoil and muzzle flash.

Legal Status

Before diving into your build, it’s crucial to understand the legal landscape. According to the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), the lower receiver is the firearm’s serialized part. This means it requires a Federal Firearms License (FFL) transfer.

However, the other parts in an AR build kit do not require an FFL and can be purchased online. Some states have specific laws that restrict certain parts or the sale of 80% lowers (partially finished lower receivers). For instance, states like California, New York, and New Jersey have stringent regulations.

The Biden administration has also focused on regulating “ghost guns,” which are firearms built from parts without serial numbers. As of April 2022, kits that can be easily assembled into functional firearms must include a serial number and require background checks for purchase.

Fact: A senior administration official stated that the ATF could trace fewer than 1% of roughly 45,000 ghost guns linked to criminal investigations between 2016 and 2021 .

Understanding these legal requirements ensures that your build is compliant and safe. Always check your local and federal laws before starting your project.

Next, we’ll explore the different types of AR build kits available, helping you decide which one is right for your needs.
