Dominate the field with Trijicon's 4x32 ACOG BAC Dual-Illuminated Riflescope. This almost-indestructible (7075-T6 aluminum alloy body) and self-powered (battery-free) Advanced Combat Optical Gunsight (ACOG) offers a low-distortion 4x optical system and an illuminated red Crosshair ballistic reticle to help you achieve your goals. The reticle is optimized for 300 Blackout ammunition and features a dual (tritium and fiber optic) illumination system that does not require any electrical power and can run for years. It automatically adapts to the environmental lighting conditions and delivers a highly visible reticle pattern. The optical system complies with the Bindon Aiming Concept (BAC), allowing you to aim with both eyes open. This ACOG provides a 1/2 MOA windage and elevation clicks, and ships with a TA51 mount for attachment to your firearm.

        Q: 1. Specs say this RCO is designed for 14.5 inch barrel. Will it be ok on a 16 inch barrel? Trajectory of a 5.56 is pretty comparable regardless of barrel length I thought.

        A: The problem is one of velocity, not so much barrel length. Generally speaking the longer the barrel the higher the velocity. The difference in barrel length is 1 1/2 inch but remember that rarely does manufacturer specs match up with the actual velocity, too the outside temperature will affect the actual velocity. Unless you are a purist the difference is not worth worrying about. Also, the 223/5.56 is a very flat shooting cartridge, depending on the load and I am assuming a standard 55 grain load. With the right zero the bullet will never be more than 3 high or 3 low out to over 300 yards. If you hand load it would be a very easy matter to adjust the velocity if you felt the need to do so. Regardless of what ammo you shoot there will be variances in velocity unless you have match grade ammo. You can zero this scope wherever you want with the added benefit that it has range finding ability. By the way, the horizontal line is NOT for windage . . . . . the Chevron is used for that. The horizontal line is in Mil's . . . . . read the manual.
