This video debunks the myth that standard AR-15s are sub-MOA sniper rifles. It explains that M193 ammunition's specification (MIL-C-9963F) allows for up to 3 MOA, and military testing of M16s showed accuracy ranging from 2.6 to 4.3 inches at 100 yards from a machine rest. The speaker emphasizes understanding equipment limitations and improving personal shooting fundamentals to set realistic accuracy expectations.

Quick Summary

Standard AR-15s are not sub-MOA sniper rifles. M193 ammunition's MIL-C-9963F spec allows up to 3 MOA, and military M16 testing showed 2.6-4.3 inch groups at 100 yards from a machine rest. Focus on improving your shooting fundamentals for better accuracy.

Frequently Asked Questions

What is the expected accuracy for M193 ammunition?

According to MIL-C-9963F, the military specification for M193 ammunition, the average mean radius should not exceed 2.0 inches at 200 yards. This roughly translates to an acceptable accuracy of around 3 MOA.

How accurate are standard AR-15 rifles like the M16?

US Army testing of the M16 rifle, fired from a machine rest at 100 yards, showed accuracy ranging from 2.6 to 4.3 inches. This indicates that standard military rifles are not inherently sub-MOA precision instruments.

What factors affect AR-15 accuracy?

AR-15 accuracy is influenced by ammunition quality, barrel profile (e.g., pencil vs. heavy), and crucially, the shooter's fundamentals, including sight picture, trigger squeeze, grip, and breathing control.

Should I expect my AR-15 to be a sub-MOA sniper rifle?

No, it's a common misconception. Standard AR-15s, especially those with pencil barrels, are not designed for consistent sub-MOA accuracy. Understanding the specifications for ammunition and military rifle testing helps set realistic expectations.
