What is Minute of Angle (MOA)?

MOA is the abbreviation of the term Minute Of Angle. MOA is commonly used to describe the relative accuracy of a firearm. MOA is also less commonly described as Minute of Arc or Arcminute.

Calculating MOA is usually undertaken in empirical measurements ie inches and yards.

Fundamentally, MOA is 1/60th of one degree. A full circle is divided into 360 degrees and each degree is divided into 60 minutes. Thus, there are 21,600 minutes in a full circle (360 x 60 = 21,600).

Therefore, to calculate MOA, imagine a very large circle with a 100 yard radius (distance from the circle centre to the edge of the circle). This circle would also have a circumference (the full perimeter distance of the circle) of approximately 628.32 yards or 22,619 inches.  By dividing the circumference (22,619 inches) by the number of minutes in a full circle (21,600 inches) gives a value of about 1.047 inches (22,619 / 21600 = 1.047). Similarly, the size of a bullet's impact point would change by 2.094 inches at 200 yards (1.047 x 2) and change by 3.141 inches at 300 yards (1.047 x 3) and so on.

So, if you calculate 1/60th of a degree when firing a rifle at a target 100 yards away, the measurement between the two lines of the angle that radiate from your shooting position to the target 100yards away is 1.047 inches or approximately 1 inch.

A major concept that most target shooters or hunters need to understand is that for every firearm and ammunition combination employed there will be a specific and individual MOA value associated with that combination. We are considering purely MOA in this discussion, however it should be noted that there are factors or variables that impact on the MOA. Such obvious factors are the variances attributed to the expertise of an individual operator of the firearm.

In evaluating MOA potential of a particular rifle and ammunition combination, it needs to be highlighted that precision and accuracy do not mean the same thing.  That is, rifle precision is a measure of how close a bullet will hit at the same point it had before. Where, rifle accuracy is hitting the aiming point. When combing precision and accuracy, where the point of aim coincides with accuracy we call this MOA Performance.

Therefore MOA is a concept that provides the shooter a reference point for evaluating Performance of any combination of firearm and ammunition. 

By understanding the MOA Performance concept it is also possible to provide an understanding at what ranges a shooter could conceivably hit targets, particularly at long distances. In deed, if all things are made equal, it also provides feed back as to the ability of the operator.

BulzEyePro Optical Boosters

MOA Performance proudly introduces the BulzEyePro Optical Boosters to the Australian shooting enthusiast.

BulzEyePro has created a revolutionary new product that boosts the magnification of your rifle scope without any modification to your scope. It is an eyepiece lens extension that fits on your rifle scope between your eye and the end of the scope.

The Optical Booster comes in a number of different strengths from 2X right up to 13X for special applications.  Generally though the magnifications available will be 2X, 2.5X, 3X, 3.5X, 4X, 4.5X and 5X.

Application of the BulzEyePro Optical Booster

Essentially a 2X version of the Optical Booster can increase an image size by approximately 15% while a 3X Optical Booster can boost the viewed image by about 30%.  Therefore, as an example a 25X scope with a 3X Optical Booster creates the equivalent of a 32X scope.  Or for the bench rest shooters using a 3X Optical Booster on a 45X scope will see the image as though you were looking through a 58X scope! 

There are many magnifications and versions available to meet the need of the shooting enthusiast for a wide cross section of applications, including hunting and varmint shooting and competition shooting.

Further Beneifits

There are versions of the lens that are designed for specific purposes such as long distance competition shooting.  As an example, the use of a multicoated polycarbonate lens can reduce or negate the affects of mirage and parallax errors.

Bulzeyepro state that their Optical Boosters will address and correct every known optical illusion experienced by scoped firearm shooters while improving safety, and increasing size and clarity of targeted image.

As we age, our shooting ability should not decline due to diminished eyesight. The Optical Booster can assist in restoring sight loss and increasing clarity of picture for all shooters and also improves firearm optics and their safety.

Hunters will enjoy quick, huge, clear, precise sight pictures with improved safety. Competitive shooters can add an enhanced ability to read mirage and adjust to zero parallax. Diabetics will also see all of this, along with a vast improvement in consistency and repeatability of shot.

Unlike an internal boosting job, you can simply remove the Booster if you want to return to the original magnification level.

In addition, the Boosters require no internal modification and will not effect the factory warranty.

Available Models

At this time there are two models available with more models to come shortly.  The two existing models include the following:

1.  Screw on model – Utilising the threads provided for lens caps on your rifle scope, a lens fixed in a threaded ring simply screws onto the rifle scope behind the eyepiece.  This model is presently available for the Leupold competition series made after 2003, Weaver T series, Sightron BR series, Nightforce BR series, and March rifle scopes.

Below is an Optical Booster fitted to scope.

2. Slip on model with Interchangeable lenses – This model offers greater versatility where a rubber housing will fit any scope with an eyepiece diameter of 1.45” to 1.8”.  Basically, this model will fit just about any 30mm and 1” tube rifle scopes.

This model provides the shooting enthusiast with the ability to move the Optical Booster from one scope to another.  Also, a variety of lenses can be inserted in the flexible rubber housing.  For example, you can switch from a 2.5X lens for say 300 yards shooting to a 4.5X Multicoated lens for extreme long range shooting without having to swap out scopes.

Below is a Slip-on rubber Optical Booster shown fitted to scope.

BulzEyePro Guarantee

In addition, BulzEyePro state that if you are not satisfied with your Optical Booster for any reason, simply return the booster within 45 days of the purchase date for a full refund of the item purchase price.

Cooper Firearms in Australia

At last, Cooper Firearms will be in Australia and proudly imported by MOA Performance.

MOA Performance is a new specialist importer of firearm products catering to predominantly the rifle and handgun shooter. MOA Performance will focus on firearm products that are renowned for accuracy, durability and quality.

As our company name implies, the focus of MOA Performance is to provide the shooting enthusiast with products that display inherent accuracy and/or products that will contribute to improved accuracy or enhance accuracy of your existing shooting systems.

The Cooper rifle embodies all of the attributes that MOA Performance look for in a shooting product.Cooper Firearms is well-known for the quality and accuracy of its varmint, rimfire, and hunting rifles. When Dan Cooper started Cooper Firearms in 1989, he summed up the direction of the company by stating:

“When I came up with the idea of Cooper Arms in 1989, I wanted to do more than make beautiful rifles. They had to be the most accurate production rifles available in the US.”

This commitment to accuracy is why in 1990 Cooper Arms were the first to guarantee ½ MOA accuracy. In fact, Cooper Arms accuracy guarantee is specifically ¼ MOA accuracy for their 22LR rifles for 5 shots at 50 yards and ½ MOA for 3 shots at 100 yards for all other rifles in the Cooper Arms line-up. The accuracy guarantee is based on match grade ammunition for rimfire and quality match grade handloads for centrefire.

Significantly, because of the emphasis of providing highly accurate rifles in a package that exhibits some of the finest gunsmithing in the world, a Cooper rifle is not necessarily for everyone. It is important to know and appreciate that the Cooper rifle is an expression of some of America’s finest rifle craftsmen.
