Call Trijicon. Their tech department can tell you the exact specs.

For what it's worth, I shoot a TA11 which was calibrated for 55gr M193 from a 20" barrel (3120fps). Instead, I shoot 75gr OTM from a 20" bbl (2650fps). At 400 yards, I'm only 5" low versus the bullet-drop stadia lines.

TechBrute: I should have asked "do you really need magnification for the duty you're pulling?" If fast reaction firing at 0-200 yards is all you really need, an EOTech will do it very well, and then you can spend $500 bucks on some other piece of needed gear. That's my opinion.
 
Just curious- If you had to clear a house with a 4x ACOG equipped M-4, how would you use a 4x scope at close range? Or would you just switch to the tube mounted irons?
 
Regarding red-dot vs. ACOG:

At SMM3G just two weeks ago, the short-range CQB in-the-darkhouse stage was won by a guy shooting a TA11 ACOG (3.5X). The long-range rifle stage (300 yards) was won by a guy with a Holosight.

Go figure.

The Nature of Binocular Sighting

Human vision is based upon a binocular (two eyes) presentation of visual evidence to the brain. The word binocular literally means using both eyes at the same time. We most often associate this word with binocular instruments such as field glasses or a binocular microscope. These instruments specifically strive to present the object to be viewed the same way to both eyes.

Vision research material was examined for its assistance to understand the optically aided weapon aiming process. Three major types of optical enhancement were compared. There are strong customer preferences in reticle designs, some simple reticles enhance the speed of target acquisition, others allow for greater precision in a given time limit.


The simple substitution of a bright red dot for the usual cross-hairs makes it very easy to keep both eyes open. Just as in the Single point or Armson O.E.G. sighting, the brain merges the two images. During dynamic movement, the scene through the telescope blurs because the image moves more rapidly due to magnification. The one eye sees the bright dot against the blurred target scene, so the brain picks the scene from the unaided eye. The shooter swings the weapon towards the target while perceiving the dot indicating where the weapon is pointed. As soon as the weapon begins to become steady in the target area, the brain switches to the magnified view.

A long search was made to try to combine the speed and non-battery features of the Singlepoint or Armson with the precision of the telescopic system. This discovery was made several years ago. Trijicon has sponsored research in the field of human vision to better understand this generic phenomenon. Although the study concentrated on the Armson O.E.G., some aspects are applicable also to the Bindon Aiming Concept.

Taken directly from the Trijicon website; please don't sue me I am an insignificant working stiff.
 
I've got a $700 scope on a $495 rifle. Couldn't be happier!

I'm getting the same $700 scope for a $1600 rifle too.

Forget silly hangups, use what works and/or what you like.

9mmMike, I am sure your buddy will get the gear he needs in a most timely fassion thanks in part to the class of people we have here at THR.
 
Brownells carries them also. Ask about military discount.

Retail is about $1000 bucks , their discounted price is approx $870

I got my TA31F today.
I am glad I didn't spend weeks looking for the absolute lowest rock bottom price. I am going to take the time I saved and shoot it as soon as I finish my Burrito Supreme. :uhoh:
