Trijicon ACOG 4x32 Overview

The 4x32 ACOG Riflescope with Dual Illumination from Trijicon is an Advanced Combat Optical Gunsight that is well-suited for targeting in a wide range of weather and lighting conditions and features a ballistic green Chevron reticle with tritium and fiber optic illumination. This reticle has bullet drop compensation marks that are calibrated specifically for 5.56x45 M193 ammunition.

Trijicon's battery-free dual-illumination reticle system employs a tritium phosphor lamp for low-light and night targeting, and a fiber optic illumination which makes the reticle glow proportionally to the amount of daylight. Additionally, this ACOG provides a ½ MOA per click impact point correction, and has a TA51 mount with two thumbscrews for clamp-on attachment to a Picatinny rail.

A folded light path and multicoated optics allow the ACOG to transmit a bright and wide field of view using a relatively compact form factor. Complementing the ACOG's optical system and caliber-specific ballistic reticle is a nitrogen-filled, aluminum housing that provides the durability needed for reliable performance in a wide range of shooting conditions.

Placed the order easily. Optic was delivered on time and in perfect condition. I feel I got the lowest price available at the time. I would highly recommend B&H to anyone. As expected, the Trijicon optic work perfectly!

Packed Well Unlike Previous Purchase From A Different Vendor Who Couldn't Understand Why I Was Upset That My 4-digit Price Item Arrived In A Bubble Envelope...

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.
