Trijicon ACOG 4x32 Overview

The 4x32 ACOG Dual-Illuminated Riflescope from Trijicon features a battery-free illuminated ballistic reticle and a durable waterproof housing to create a versatile weapon sight that is well-suited for use in a wide range of weather and lighting conditions. This Advanced Combat Optical Gunsight (ACOG) sight is outfitted with a green duplex crosshair reticle that has bullet drop compensation stadia on the lower vertical hair that are specifically calibrated for .223 caliber ballistics. Anti-reflection broadband fully multicoated optics maximizes light transmission to provide bright and clear views with limited distortion.

Trijicon's battery-free dual-illumination reticle system employs a tritium phosphor lamp for low-light and night targeting, as well as a fiber optic illumination that automatically adjusts reticle brightness when operating in daylight. The reticle’s aiming point can be adjusted in 1/2 MOA increments, and an internal adjustment mechanism allows the ACOG to reliably hold zero. The ACOG is outfitted with a TA51 mount that has two thumbscrews for clamp-on attachment to a Picatinny rail. Complementing the ACOG's optical system and caliber-specific ballistic reticle is a nitrogen-filled, aluminum housing with a wear, corrosion, chemical, chip, and scratch-resistant Cerakote ceramic coating that provides the durability needed for reliable performance in a wide range of shooting conditions.

question

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.
Asked by: H G.
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.
