The .223 Remington is a popular rifle cartridge that shares almost the same external size dimensions with the 5.56x45mm NATO round. It comes in different weights depending on the manufacturer, with options ranging from 40 to 90 grains. Bullets weighing 38-55gr (2.5 to 3.6g) are mostly used with bolt-action varmint rifles that offer a 1-in-12 rate of twist. Heavier .223 Remington rounds of up to 69gr are mostly used on law enforcement or home defense semi-automatic rifles such as the Ruger Mini-14 and AR-15s, which are commonly found to have twist rates of 1-in-7, 1-in-8, or 1-in-9.
Generally, the small and fragile .223 Remington rounds splinter on impact, allowing almost no penetration through the target. While this fragmentation and lack of penetration is a desirable trait when looking to incapacitate a target, it calls for precise shot placement. The concern for insufficient penetration also leaves almost no room for error. Additionally, nothing increases accuracy when firing .223 Remington ammunition than a good riflescope.
If you’re looking to outfit a .223 caliber rifle with a scope, then you need to find one that can take full advantage of this round’s effective range. The .223 Remington has a maximum effective range of up to 600 yards on a calm day. However, its progressive loss of velocity and the effects of wind greatly compromise accuracy and effectives at such long distances. When used within fairly short distances of 100-300 yards, this round can deliver lethal terminal ballistics with a greater level of accuracy.
With these facts in mind, it becomes easier to match your .223 Remington rifle with a scope that will provide ample magnification. However, there’s still a lot more to consider when selecting the best scope for 223 caliber rifles. For instance, any good riflescope will need to be durable, versatile, and provide excellent light transmission as well as optical clarity. The following are three of the best .223 scopes that match these criteria while giving you a good range of price points from which to choose.
- Generous, Consistent Eye Relief-Keeps your brow safe-even with the heaviest recoiling cartridges, lightweight rifles, and severe shooting angles.
- BDC 600 Reticle-Developed specifically for the trajectory of the .223 Rem /5.56 NATO round with 55-grain polymer tip bullet, the BDC 600 reticle offers shooters unique open circle aiming points and hash marks from 100 to 600 yards.
- Precise, 1/4-MOA Hand-turn Tactical-Style, Zero-Reset Turrets-Positive click reticle adjustments get you zeroed in quicker and maintain your setting-even withrepeated recoil.
- 100-yard Parallax Setting-Eliminates parallax for precise shooting.
- Waterproof/Fogproof-Nitrogen filled and O-ring sealed
Nikon produces riflescopes designed for specific calibers in their P series line. As the name implies, the Nikon 3-9x40mm P223 (Review) was precisely designed for the .223 Rem round. This feature-rich model packs a lot of value for scope priced in the mid-range section.
