A Shooter’s Guide to the Trijicon Accupoint

Trijicon may be best known for its ACOG, but they also manufacture a series of variable powered scopes that match its high build-quality and unique design.

The Trijicon Accupoint series has become the go-to choice for hunters and defensive shooters who are looking for zoom flexibility paired with reliability. Here we’ll dig into the Accupoint’s features and specs to see why it has become such a popular scope.

Trijicon Accupoint: Features

trijicon 1One of the best options for an upgraded rifle optic is a variable powered scope that allows shooters to adjust the zoom level according to their needs at any given time.

This on-the-fly versatility can make just a single scope suitable for a broad range of shooting applications. With simple and quick magnification and focus rings the Accupoint provides this exact functionality.

A major selling point of the Accupoint is the illuminated center of each available reticle pattern. This feature gives shooters a solid aimpoint that is viewable in any lighting condition and constrasts well against both targets and backgrounds. Quicker target acquisition and increased precision are the benefits here.

Even more interesting is the power source behind the reticle – a combination of tritium phosphor lamp and fiber optics makes for self-illumination that is entirely battery free. Savings on weight and added reliability are gained here. More details on this below.

Accupoint scopes are built to last through the wear and tear that yearly hunting seasons and extended field use can bring. The matte-black housing is made from aircraft-grade aluminum and comes dry-nitrogen filled to prevent any lens fogging; something you’ll really appreciate on cold days in the woods.

The lenses themselves are multi-layer coated to provide maxium light transmission – a necessity when it comes to low-light shooting during the early mornings and late evenings while hunting.

Windage and elevation turrets are found on the top and side and are finger adjustable at 1/4 MOA clicks. There are both picatinny and weaver mounts available, and the scope’s tube diameter will fit in most standard sized rings.

Available Sizes

The Trijicon Accupoint is available in a handful of different magnification ranges which each share the same baseline features described above. There are four different configurations which span the a gamut of close- mid- and long-range shooting. Out of all these options shooters should have no trouble finding one that is right for their setup.

Determining which  magnification to use depends mainly on the type of shooting application it will be intended for. There’s a balance of power, weight, size, and functionality that plays into it. Here are some general guidelines to follow:

accupoint31-4×40 – For shooters who are engaging targets at close to mid ranges this magnification span is ideal. Its size, weight, and max zoom makes this scope a great pair for defensive carbines or rifles that need a boost over their iron sights (5-200 yards)

2.5-10×56 – With a large objective and reasonable magnification this scope is best suite for hunters. The lens can gather plenty of light in dim mornings or evenings while the zoom makes for accurate kill shots on game at semi-distant ranges (10-600 yards)

3-9×40 – This scope is another solid hunting option with a different balance of magnification and size. It trades off some maximum zoom for a smaller body that’s less bulk and easier to trek through the woods with (50-500 yards)

5-20×50 – This is a specialized scope that will be used almost exclusively for long range work. Its bulky size and weight likely reserves it for either a dedicated bench rest rifle or sniper rifle built for extreme range (50-700 yards)

Reticle Styles

For each of the Accupoint’s different size options there comes a number of reticle options to choose from as well. The available reticles vary both by pattern and color, and choosing the right one can depend on everything form the distances you’re shooting at to what kind of targets you’re after.

triangle postTriangular Post – This pattern is great for shooters who don’t like a lot of ‘clutter’ in their sight picture. Its minimalist design is simply made up of a centered triangle with vertical lines extending to the bottom edge, preventing any unwanted target occlusion. Zero at the triangle’s peak for a precise aimpoint.

duplexStandard Duplex Crosshair – This is the most common pattern found in today’s scopes which consists of crosshairs that are thin at the center and thicker towards the outside perimeter. The thick bars are easy for the eye to catch against a busy background and trace along towards the center where the thin lines allow for exact aiming.

germanGerman #4 Crosshair – This option is only available in the 1-4×24 version and differs slightly from the Duplex Crosshair in that it has shorter, thicker perimeter bars, on of which is not present along the top. This opens up the sight picture above targets and bracketing the target between the bars makes for quick target acquisition.

mildotMil-Dot Crosshair – This type of crosshair features ‘mil-dots’ lining each axis which can be used for rudimentary target range estimations. The space between each dot corresponds to one mil, or milliradian, that’s equivalent to 3.6 inches at 100 yards. By knowing the target’s actual size and then viewing how many dots it spans in the FOV a simple calculation will tell you the range to it.

Each reticle aimpoint, either the crosshair center or triangle, is illuminated in one of three colors: red, green, or amber. Each of these can get plenty bright to contrast against any background, so the choice in color mostly comes down to personal preference.

AccuPoint-Features3Like most variable scopes the reticle falls on the second focal plane of the Trijicon Accupoint. Essentially, this means that as the magnification is increased the reticle size remains constant in the FOV, which makes it smaller and more precise relative to a target at higher magnifications.

It should be noted that this has an effect when using the Mil-Dot reticle. Because the reticle stays a constant size the dot spacing only accurately represents a measurement of one ‘mil’ when the scope is set to its maximum magnification. At all other magnifications the target range formula using the mil-dots is inapplicable.

Fiber Optic & Tritium Powered

Any illuminated reticle is going to require a power source in order to operate. Typically, this comes in the form of an internal battery, but the Trijicon Accupoint instead utilizes two different technologies which together provide constant illumination in any lighting condition. Event better, they are both completely passive and require no batteries at all.

accupoint2Along the top of the Accupoint, in front of the eye piece, you’ll find a small cutout that exposes colored filaments to the light. These are fiber optics, one of the power sources that work by collecting ambient light from the shooter’s surrounding environment and piping it through the scope to the reticle.

As shooters move from darker to bright areas the fiber is able to pick up more incoming light and in turn make the reticle brighter. This acts as an auto-brightness adjustment that keeps the reticle visible in changing lighting conditions. Shooters also have the option of sliding a cover over the cutout to gain some manual control over the brightness.

In low- or no-light, when the fiber optics aren’t able to pick up enough light to illuminate the reticle properly, the primary power source becomes the scope’s internal tritium phosphor lamp.

Within each Trijicon Accupoint is a small capsule of tritium gas, a radioactive isotope of hydrogen. The gas is in a constant state of decay in which it is emitting electrons that react with surrounding phosphor, creating fluorescent light that powers the reticle. The tritium used is perfectly safe and has become a common power source for other Trijicon sights.

The real benefit of using a tritium phosphor lamp is that it runs 24/7, day and night; there is no ‘off’ switch here. Tritium is incredibly long lasting and is warrantied by Trijicon to keep illuminating for 15 years.

Its independence from batteries makes the Accupoint very reliable. You’ll never have to worry about batteries draining in storage or dying while you’re out in the woods. Saving on space and weight is an added bonus as well.
