The Trijicon ACOG is still the most practical, durable and reliable combat optic. They are being used in combat for long range and close quarters combat roles and many troops use the low magnification to identify wires running to IEDs from hundreds of yards away. Increase your proficiency and firearm speed with optics that are setup for shooting military grade ammo. Illuminated reticles will void the need for storing batteries for gun sights that become useless when the batteries die. The AR15/M16 family of rifles are the most versatile combat Carbine. Trijicon optics are also one of the best chooses in using these rifles due to the variety of bullet reticles and optic chooses.
The M4 is a very capable close quarters optic, and the 556 round is very accurate at long ranges. Having the ability to get an accurate hit on target at 200-600 meters is a challenge with standard reticles, but the Trijicon family of rifle scopes has bullet compensators for fast engagements at long ranges. Trijicon ACOGs and Trijicon Accupoint rifle scopes give you broad uses and configurations. Understanding the limitations of a rifle is important, but knowing how to use your carbine or rifle to it's fullest is another. The Trijicon Accupoint rifle scopes are very good for hunting. They are available in red and green dot. There are also combat optics available for .308 rifles with the same style of optics that are available for the .223 and are capable of taking the beating that the 7.62 round can do to rifle optics.
