Ruger AR 556 MPR Problems: A Comprehensive Guide

Ruger, a renowned American firearms manufacturer, has been producing quality firearms suited for both civilian and military use since 1949. One of their popular products in the market today is the Ruger AR 556 MPR Multi-Purpose Rifle. This firearm is a variant of the AR-15, distinguished by its 18-inch barrel, free-float handguard, and Ruger’s two-stage trigger. However, like any other firearm products, the Ruger AR 556 MPR is not perfect and does have its fair share of challenges and caveats.

Examining Ruger AR 556 MPR Problems

Issue 1: Cycling Issues

One common issue observed among the Ruger AR 556 MPR users is the cycling issue. In some cases, users may experience instances where the firearm fails to feed or eject the cartridge properly. This can be caused by multiple factors such as insufficient gas pressure, defective magazines, or merely the characteristics of the ammunition being used. It can affect the overall performance of the firearm, causing delays and frustrations during shooting sessions.

Issue 2: Trigger Concerns

The Ruger AR 556 MPR is designed with a two-stage trigger that offers a smooth, sturdy pull. However, a number of users have reported issues with the trigger failing to reset after firing a round, causing the gun not to fire at all. This trigger issue is worrying as it can lead to unexpected firearm malfunctions that could escalate safety risks.

Issue 3: Barrel Accuracy

Barrel accuracy is crucial in a firearm, and unfortunately, some users have reported this as an issue in the Ruger AR 556 MPR. Inconsistent groupings and deviations from the point of aim can be alarming for expert shooters. This could be attributed to various factors, including the quality of the barrel, the type of ammunition, or even environmental factors such as wind speed and temperature.

Addressing Ruger AR 556 MPR Problems

Solution 1: Resolving Cycling Issues

To troubleshoot cycling issues, first, check if your firearm is well lubricated; lack of adequate lubrication can contribute to cycling issues. Try using different brands or loads of ammunition to establish if it is an ammunition-specific problem. Also, consider checking if you are using quality magazines; inferior magazines can lead to feeding issues.

  1. Check the gas block and gas tube alignment. Incorrect alignment can prevent proper cycling.
  2. Clean the firearm regularly. Dirt, sand or any debris can restrict the firearm’s action.

Solution 2: Addressing Trigger Concerns

Fixing the trigger problems is a bit more complex and might require the expertise of a gunsmith for you not to alter the firearm’s original structure and potentially void its warranty.

  1. Ensure the gun is not overly dirty – excessive dirt and carbon buildup in the trigger mechanism can cause malfunctions.
  2. If the problem persists, consider a trigger upgrade or replacement. Be sure to consult with a professional to ensure proper installation and functionality.

Solution 3: Improving Barrel Accuracy

Improving barrel accuracy involves a bit of experimentation.

  1. Try using different brands or types of ammunition. Some firearms prefer certain ammo while others may perform poorly with the same ammo.
  2. Control environmental factors. Learn to adjust your shooting to compensate for factors such as distance, wind direction, and speed.
  3. Consider seeking the help of a gunsmith for a potential barrel upgrade if problems persist.
