Frequently Asked Questions

What is Larry Vickers' 50% Rule for carbine reliability?

Larry Vickers' '50% Rule' is a set of four simple techniques designed to eliminate at least half of potential malfunctions in AR-15/M4 style carbines. It involves specific methods for magazine loading, lubrication checks, magazine seating, and charging the weapon.

How should I load a magazine according to LAV's 50% Rule?

Load your magazine to its full capacity, then remove two rounds. Use the 'thumbnail trick' to ensure the top round can be depressed enough to clear the magazine feed lips easily, preventing feeding issues.

What is the correct way to seat a magazine for maximum reliability?

To ensure a secure magazine seat, anchor the buttstock firmly. Then, use a 'push-pull' method: push the magazine firmly into the well, and then pull on it to confirm it's locked securely in place.

Why is proper lubrication important for AR-15 reliability?

Adequate lubrication on the bolt and bolt carrier group is essential to prevent friction-related failures. Visually inspecting these components through the ejection port and adding oil if dry can prevent stoppages.
