A Comprehensive Guide to Buying Your First AR-15

The AR-15 rifle is one of the most popular sporting rifles in America, known for its modularity, versatility, and wide range of customization options. Whether you are a first-time buyer or looking to upgrade your current rifle, understanding the essentials of buying an AR-15 will help you make an informed decision that fits your needs and budget.

Understanding the AR-15 Platform

The AR-15 is a modular rifle primarily composed of two main parts: the lower receiver and the upper receiver. The lower receiver is the serialized firearm component that houses the trigger mechanism and controls, while the upper receiver contains the barrel, bolt carrier group, and other components. This modular design allows users to swap uppers easily, changing calibers or barrel lengths without purchasing a new firearm.

This flexibility means you can have multiple uppers for different purposes—ranging from long-range precision shooting to close-quarters combat carbines—paired with a single lower receiver, simplifying ownership and paperwork.

Popular Calibers and Uses

  • 5.56 NATO / .223 Remington: The most common calibers for general use, including target shooting and home defense.
  • .300 Blackout: Popular for suppressed shooting and hunting.
  • .22LR: Great for training and plinking due to low recoil and cost.
  • .50 Beowulf: Used for big game hunting and specialized applications.

What to Consider When Buying an AR-15

1. Purpose and Use

Define what you want your AR-15 for: target shooting, hunting, home defense, or competition. This will influence your choice of barrel length, caliber, and accessories.

2. Budget

AR-15 rifles come in a wide price range. Entry-level models can be affordable, while premium rifles with high-end components and factory upgrades cost more. Consider what features are essential versus nice-to-have.

3. Build vs. Complete Rifle

You can buy a complete AR-15 rifle or build one from a kit. Building from a kit can be rewarding and educational, allowing you to customize every part. Kits often come with a pre-assembled upper receiver, making assembly easier.

4. Quality and Brand

Look for reputable manufacturers known for quality and reliability. Some brands come with factory-installed premium parts like Geissele triggers, Radian charging handles, and Criterion barrels, which can save you upgrade costs later.

Step-by-Step Guide to Buying and Building Your AR-15

  1. Research and Choose Your Model: Read reviews and compare models based on your needs. Consider expert recommendations and user feedback.
  2. Check Local Laws: Ensure compliance with your state and local firearm regulations, as some states have restrictions on features or require specific permits.
  3. Purchase from a Licensed Dealer: Buy from a Federal Firearms License (FFL) dealer to ensure legal transfer and background checks.
  4. Consider Accessories and Upgrades: Plan for optics, slings, lights, and other accessories that enhance your rifle’s performance and usability.
  5. Assemble (if building): If you buy a kit, prepare your workspace with essential tools like a bench vise, armorer’s wrench, roll pin punches, hammer, and torque wrench. Start with installing small components on the lower receiver, attach the buffer tube and stock, then mate the lower to the upper receiver. Perform function checks to ensure proper operation.

Maintenance and Safety

Owning an AR-15 requires regular cleaning and maintenance to ensure reliability and longevity. The modular design makes disassembly and cleaning straightforward. Always follow firearm safety rules:

  • Treat every firearm as if it is loaded.
  • Keep your finger off the trigger until ready to shoot.
  • Never point the firearm at anything you do not intend to destroy.
  • Be sure of your target and what is beyond it.

Popular AR-15 Models to Consider

  • ADM Mod 2: Known for out-of-the-box readiness with premium parts like Geissele triggers and Criterion barrels, suitable for duty use and precision shooting.
  • Stag Arms STAG 15L Tactical Lefty: A unique left-handed AR-15 with mirrored controls and ejection port, highly praised by left-handed shooters.
  • Dirty Bird and NBS Rifle Kits: Affordable and reliable kits ideal for those wanting to build their own AR-15.
