AR-15 Gun Builder

All About the AR-15 Gun Builder

The AR-15 is a general term used to describe many brands and models and calibers of sporting rifles, which generally the same look and design. They are usually black, although desert tan and earth green are also popular colors. They typically have adjustable stocks, detachable magazines (usually 30 rounds), and pistol grips, and they readily accept many types of aftermarket accessories.

The AR-15 was originally designed by Eugene Stoner of ArmaLite Corporation for submission to the U.S. Armed Forces to become their primary service rifle. (AR, by the way, stand for ArmaLite Rifle, not Assault Rifle as many believe). Although the AR-15 was not immediately selected by the Armed Forces, it raised some eyebrows and gained some high-ranking supporters.

Several years later, and after the Secretary of Defense himself intervened, the AR-15 was adopted by first the U.S. Air Force and then the U.S. Armed Forces. With that, it was redesignated as the M16. The original AR-15 that Stoner designed for the Armed Forces was chambered in 7.62x51mm NATO (.308 Winchester). Stoner changed the design to feature the new 5.56mm NATO (.223 Remington) cartridge when it wasn’t selected.

Today, 5.56mm is the most common AR-15 cartridge, but they are available in various sizes. .300 AAC Blackout, .308 Winchester, 6.5mm Grendel, 6.8mm Remington SPC, 9X19mm Parabellum, and .22LR are some of the more popular alternatives to 5.56mm.

AR-15 Accessory Guide

One of the best features of AR-15s is the massive amount of accessories available for it. There are entire companies dedicated to making only AR-15 aftermarket accessories. I’ve listed some of the best accessories for AR-15s below.

Optics

Optics

Optics such as scopes allow you to magnify the target so that it appears closer, improving your accuracy. This is helpful when shooting long distances. The AR-15 is moderately accurate at ranges over 300 yards. It’s not as accurate as a sniper rifle, but better than some other rifles on the market. Adding a scope to your AR-15 will extend its effective range.Another optic popular with AR-15 owners is the red dot reflexive sight. These do not magnify the target but provide an illuminated dot or reticle, making close and mid-range target acquisition faster and more accurate.

Collapsible Stock

Collapsible Stock

The collapsible stock is one of the features that identify the AR-15. Many companies make aftermarket stocks that you can add to your AR-15. The benefit of a collapsible stock is to make the overall length of the rifle shorter, in situations such as close-quarters battle (CQB). If you are part of a team going through a building, you will want your AR-15 as short as possible for maneuverability. Also, the reduced length does little to affect accuracy at such close distances.

Handguards and Forward Grips

Handguards and Forward Grips

Another way to customize your AR-15 is to add custom handguards and a forward grip. The handguards are where you place your support or non-firing hand when aiming. Using a forward pistol grip provides you with better positive control while firing, as well as keeping a better hold while firing and moving.

Slings

Slings

Slings are an often-overlooked accessory, but if you ever need to use your hands while also have your rifle nearby, a good sling is essential. Slings are categorized by how many connection points they have on your rifle. There are single-point, double-point, and triple-point slings. Single-point slings allow for the best shooting without the sling getting in the way, while double and triple-point slings offer better weapon retention while moving.
