While we still can, building AR-15 pistols is not only prudent in terms of avoiding arguably unnecessary fees paid to the ATF, but also prudent in terms of sheer maneuverability, portability, and suitability for a home defense weapon. While pistols are great at being concealed, and much easier to maneuver in tight spaces, they lack a lot to be desired for when it comes to handling accurately and effectively when compared to a rifle or a braced AR-15 pistol. To create a reliable and effective home defense firearm, you need to define your purpose, choose the ammunition, and components, optics, sights, ammunition, and accessories for your AR-15 pistol and today we’re going to show you how we think you should do that.
Build Around YOUR Home
Consider the layout of your living space, potential barriers, and the specific risks you may face at home. Tailor your AR-15 pistol to meet these needs effectively. Once you have a clear understanding of your requirements, proceed to choose the right caliber and components. Opt for a suitable caliber, such as 5.56x45mm NATO or .300 AAC Blackout, and select a barrel length that can still utilize a fair amount of the muzzle velocity potential for the cartridge but won’t compromise your maneuverability in your home.
Shorter barrels about 12” or under increase maneuverability in close quarters. Ensure that the upper receiver, barrel, handguard, and gas system come from reliable and reputable brands as you want to eliminate any potential hiccups when it comes to reliability. You could arguably opt for a barrel even shorter than 8” but at this point, the AR-15 pistol loses a lot of effectiveness even at short ranges (under 50 yards). While this might not be a concern inside the home, also keep in mind that the shorter the barrel is, the louder the firearm will be even if you select subsonic ammo and use a suppressor.
Optics and Sights
For quick target acquisition, equip your AR-15 pistol with a red dot sight or holographic sight. These options allow you to quickly aim at potential threats during critical moments. Modern red dots are extremely reliable, affordable, and have batteries that last for years when left on or even have shake-awake features that ensure your optic is on and ready to go as soon as you pick up the AR-15 pistol.
As an extension to sights, a weapon-mounted flashlight might be a wise accessory to add to the mix along with a tape switch for easier activation. Since most home invasions tend to happen during the darker hours of the day, having a flashlight not only means you’ll be able to see any potential threats but also confirm that the unknown person in your house is actually a threat.
Ammunition Selection
Opt for reliable, high-quality, hollow-point ammunition specifically designed for self-defense. This choice helps minimize over-penetration and enhances stopping power out of shorter barrels. Companies like Hornady, Federal, and a few other boutique ammo manufacturers make great self-defense 300 blackout and 5.56 ammo that should stop virtually any threat that might enter your home unannounced.
One thing to keep in mind and even test for is the reliable expansion of self-defense ammunition out of your selected barrel length. Hollow Point ammo expands to deal more lethal damage and shorter barrels might rob the ammo of its ability to expand in targets due to the lower velocity. Shooting the ammo into a couple of layers of denim into a couple jugs of water or even ballistics gelatin should help confirm if your ammo remains effective out of your short AR-15 pistol barrel.
Closing Thoughts
Remember, building and owning an AR-15 pistol is a significant responsibility. Prioritize safety, proper storage, and ensure the firearm is kept out of reach of unauthorized people who may enter or be in your home, especially children if they are untrained. If you are unsure about the building process, seek advice from a knowledgeable gunsmith or firearms instructor. Regularly practice shooting and attend training courses to become proficient in handling your AR-15 pistol. Familiarize yourself with your firearm's capabilities and limitations. By following these guidelines and taking necessary precautions, you can have a well-built AR-15 pistol that serves as a reliable tool for home defense and possibly even beyond.
