Firearm Forum Question: What is M.O.A.

Ask A Firearms Question:
New to shooting with a scope. Can you explain and define MOA?
How does MOA determine the Rifle Scope I use?
Thank you Ty Haden.

Subsequent related question -
I have a Remington Model 750, 30-06 Rifle. I want to install a Picatinny Rail on my Rifle. How many minutes of angel does this rifle have?
Thank you Mr. Puma.

MOA is an abbreviation that stands for - 
Method of Angle
The Definition of M.O.A. is:
MOA is essential a convenient method for shooters using English units to measure angle.
One (1) MOA = 1.0472 Inches at 100 Yards (91.44 meters).
Rifle Scope Manufacturers and Shooters both simply round the 1 MOA = 1 Inch, which makes MOA a handy unit to use in ballistics.
One of the most common reticles in Optics is to use a Red Dot which is placed on the target by the shooter. These are generally a small Red Dot measured in 5 MOA. The Dot size is generally 1.5 mrad which is small enough not to obscure the target but large enough to quickly acquire a target.
Many Optics now offer a combination of Green Dot and Red Dot. Green Dots are more visible during bright sunlight and Red Dots work better in cloudy overcast daylight, indoor shooting ranges, or night vision. These optic devices use a battery and project a dot to the target. Correct acquisition (aiming) is done by adjustments up or down and right and left, which is referred to as Vertical and Horizontal, the same method used in a Rifle Scope.
Often times in action shooting with a handgun, a larger dot is used for fast movement and accuracy.
Rifle Scopes do not use projected color optics, instead they place a cross hair or cross with a dot on the target of vision that is seen by looking through the scope with the naked eye, see photos below ....

Many Shooters use a Rangefinder to establish the distance from their shooting point to the target. This device simply sends out a laser beam and measures the distance from the target to the front of the rangefinder. These are very handy when not shooting at a gun range with pre marked target distances.
I personally use a Leupold GX-3, shown below ...

Answer :
Blog Administrator -
M.O.A. or Method of Angle is not complicated to understand if you do not read more into it than simply follow the use.
Below are 2 Youtube Videos.
The first video explains MOA in detail and how to use Method of Angle for Shooting.
The second Video explains how to choose a Rifle Scope for your needs.

As to how many minutes of angle a particular rifle has varies on every rifle, type of scope and optics used. Consult both the manual of the firearm and the manual for the scope or optics used. Hopefully the two videos below will also lend some assistance, see more after the videos.
