Handguns are typically less accurate; at a shooting distance of 25 yd, a grouping is considered acceptable for self-defense if the shots fall within a circle of 4 to 5 inches, which is 15 to 19 MOA (equivalent to a grouping of 100-150 mm at 25 meters, which is 4-6 mils), [9] representing the shot pattern needed to hit the vital organs of a ...
For 5-shot groups, based on 95% confidence, a rifle that normally shoots 1 MOA can be expected to shoot groups between 0.58 MOA and 1.47 MOA, although the majority of these groups will be under 1 MOA. What this means in practice is if a rifle that shoots 1-inch groups on average at 100 yards shoots a group measuring 0.7 inches followed by a ...
The sights move in the vertical and horizontal planes in fixed increments of (typically) 1/4 minutes of angle (MOA); as a rule of thumb, moving the sight by 1 MOA moves the impact of the shots by 1 inch (25 mm) per hundred yards distance of the target from the rifle.
Its shot-to-shot variation is expected to be better than 1 minute of angle (MOA) with match ammunition. This level of accuracy is only average compared to most modern bolt action sniper rifles, but is still exceptional for a semi-automatic rifle and at one time was claimed to be "one of the most accurate semi-automatic sniper rifles in the world."
The M24 Sniper Weapon System adopted in 1988 has a stated maximum effective range of 800 meters and a maximum allowed average mean radius (AMR) of 1.9 inches at 300 yards from a machine rest, which corresponds to a 0.6 MOA (0.17 mrad) extreme spread for a 5-shot group when using 7.62×51mm M118 Special Ball cartridges.
200 yards (183 m): 1.3 inches; 273 yards (250 m): 1.4 inches; 300 yards (274 m): 1.9 inches; The radial distance from the calculated center of impact of the first target compared to the calculated center of impacts of the subsequent targets shall be less or equal to 1.086 MOA (3.3 inches @ 300 yards, 2.2 inches @ 200 yards, 2.4 inches @ 200 ...

The USMC standard is that 1 mil (that is, 1 milliradian) equals 3.438 MOA (minute of arc, or, equivalently, minute of angle), while the US Army standard is 3.6 MOA, chosen so as to give a diameter of 1 yard at a distance of 1,000 yards (or equivalently, a diameter of 1 meter at a range of 1 kilometer.) Many commercial manufacturers use 3.5 ...
