How to Build an AR-15 for Home Defense

8th Feb 2021

There are several essential factors to consider if you're looking to build an AR-15 for home defense. Make sure you have the right firearm and supplies to protect your home safely and effectively.

6 Parts to Consider When Building a Home Defense AR-15

As you build a home defense AR-15, gather parts to help you respond quickly and safely in an emergency. The right preparation will give you the accuracy and control to neutralize a threat while keeping your home and anyone else in the vicinity safe.

1. Barrel Length

One of the first things to consider is your barrel's length — in the case of a home intruder, you will likely be firing in a tighter space, meaning that a shorter barrel will provide critical maneuverability. Just bear in mind that the barrel must be at least 16 inches in length if your firearm is configured as a rifle and you haven't purchased the required tax stamp for a short barreled rifle (SBR).

2. Sights and Optics

Having both a non-magnified optic and iron sights is a good way to be prepared for anything. In a situation where damage or battery issues might compromise the optic, backup iron sights ensure you can still place your shots accurately.

3. Muzzle Device

Muzzle devices, including muzzle brakes, flash suppressors and compensators, help you keep better control of the gun when you need to fire. With a muzzle brake or compensator, you can manage recoil to help you keep control of the firearm. The flash suppressor hides the muzzle blast so that you can maintain your night vision in low-light environments and avoid giving away your location when you fire.

4. Foregrip

With a foregrip, you can maintain a sturdy grip on your AR 15. The grip is a valuable mod for home defense that allows for positive reinforcement and responsive grip as you maneuver around tight spaces.

5. Stock

Pick an adjustable stock to give you more versatility and responsiveness for a potentially volatile situation. You can adjust the stock to the right arm length for you, helping you maintain better control of the firearm. The adjustability also makes the gun easier to store safely.

6. Light and Laser Attachments

Consider a flashlight front handguard assembly with both white and red light attachments. In areas with limited light, a red light can help you navigate and target safely and effectively. A white light, meanwhile, can powerfully illuminate a dark space while blinding your opponent.

Other Things to Consider

Along with parts, think through the additional supplies and preparation you may need for a quick response in an emergency.

  • Cartridge: When it comes to cartridges, it's essential to select the right ammo to stop the threat without completely passing through them and risking a bystander's safety. To ensure the bullet's stability as it leaves the barrel, choose cartridges that fit your barrel's twist rate, based on the bullet's weight in grains. When it comes to the type of bullet you need, a round using a full metal jacket (FMJ) projectile is typically inexpensive and works well for training. Hollow points are ideal for self-defense, as they can cause more damage while lowering the risk of complete penetration and injury of a neutral party.
  • Training: To be thoroughly prepared, ensure that you have training on techniques to protect yourself and your property. Many local police departments and other agencies offer training courses to help you prepare for and handle home intruders. You and your family should form a plan on who will do what and how to stay safe during a home defense situation.
  • Environment: Awareness of your surroundings is essential to an effective threat response. If you faced a threat to your home, think through where you would keep supplies, where you could barricade yourself and how you could navigate open spaces in your home to evade harm.
