Choosing a Scope for Your Ruger AR-556
Although the AR-556 comes equipped with a rapid-deploying folding rear sight, the right optic will increase this weapon’s accuracy and performance. The type of optic you need mostly depends on the type of shooting you do.
However, it’s important to remember both the limitations and capabilities of your weapon when choosing an optic. The Ruger AR-556 is a lightweight, highly maneuverable, lightning-fast rifle. These compact carbines aren’t long-range heroes.
The .223/5.56 cartridges the AR-556 shoots are most effective on targets from point-blank range to around 300 yards. This means you don’t need a high power optic on your rifle. In fact, the bulk and weight of a high-magnification scope will unbalance your weapon and limit maneuverability.
Ultimately, you want a compact, lightweight optic to match your compact, lightweight rifle.
Here are a few suggestions for picking a scope to match both your rifle and your shooting application.
The AR-556 is a great entry level rifle for 3-gun competition. If you want to compete in the factory division, you’ll need a red dot or holo sight. These sights are non-magnified (making them perfect for the factory division), but they will still help you get on target faster than iron sights.
Other divisions may allow shooters to use an LPVO. Topping your AR-556 with a no-to-low power variable scope delivers the ultimate in shooting versatility. You can choose 1x magnification for close range targets or zoom in on distant targets for precision shooting.
A prism scope is also a popular option for 3-gun. These compact, lightweight optics also work well for tactical applications. Prism scopes bridge the gap between red dots and magnified scopes. They offer the quick target acquisition of a red dot and pair it with a more complex reticle design. Prism scopes are highly versatile and work well for close to medium range targets.
If you plan to hunt with your AR-556, you’ll need a scope with moderate magnification. Look for an optic with a wide field of view (FOV) to help spot moving game. A scope with a BDC reticle will help you hit small vital areas on distant game.
For feral hogs and predators, a thermal or night vision scope can help improve hunting success after the sun goes down.
The AR-556 has a short barrel and lightweight design that makes it easy to maneuver in tight areas. For this reason, some shooters choose the AR-556 as a home defense weapon.
In a home defense scenario, you’ll be engaging close range targets. A red dot or holographic sight makes the perfect addition to your home defense rifle.
A Note About Price
One of the best things about the Ruger AR-556 is its price. These rifles come fully assembled and ready to shoot for well under $1000. Because the rifle is inexpensive, it’s tempting to slap a cheap scope on it and call it a day.
However, when it comes to optics, the old adage of “you get what you pay for” is completely true. If you want a quality optic, you’ll need to invest some money.
That being said, we’ve included some very affordable options on our list of top picks. We’ve tried to add something to fit every budget. Just don’t expect a budget scope to perform like a top-of-the-line model.

5 Sig Sauer Bravo 3 Battle Sight
Sig Sauer is one of Germany’s oldest and most respected weapons manufacturers. Although the company is best known for their high-quality pistols, they also do an impressive job with their optics.
The Bravo 3 is Sig’s 3x prism scope. Compact and lightweight, this optic compliments the AR-556’s design. It also won’t take up a ton of rail space.
Specially designed to provide a flat, distortion-free image, the Bravo 3 features aspherical lenses and extra low dispersion (XD) glass for incredible edge-to-edge clarity. The lenses on the Bravo 3 are also coated with Sig’s patented Lensarmor abrasion-resistant coatings for extra protection in rough shooting environments.
We also love the Bravo 3’s easy-to-use illuminated horseshoe dot reticle. This glass-etched reticle features BDC hash marks calibrated for standard 5.56 NATO loads.
6 Steiner T5Xi 3-15x50mm
Although the Ruger AR-556 isn’t exactly the perfect tool for extreme distance shooting, this Steiner scope will help you milk every ounce of long-range accuracy you can out of your rifle. You shouldn’t expect sniper-like feats of accuracy. However, the Steiner T5Xi can certainly help you put lead on targets beyond 500 yards.
The T5Xi features a unique Special Competition Reticle (SCR). This illuminated, glass-etched FFP reticle provides MOA windage and holdover lines with fine, sharp detail that is easy to see in any lighting condition. This highly detailed reticle helps you achieve the best precision shooting you and your rifle are capable of dishing out.
Steiner also built this scope to endure rough handling and extreme conditions. It is milled from a single piece of solid, high-grade aluminum stock. It is completely fogproof and waterproof. It even survives being completely submerged to a depth of 33 feet.
