ARX-100 Accuracy Tests

Published on August 20, 2014
Duration: 24:15

This review details accuracy tests of the Beretta ARX-100, revealing 'service grade' accuracy under 3 MOA, with a rail fix not significantly improving it. The Robar SR21 demonstrated impressive sub-MOA performance with match-grade .308 loads. The MGI Hydra was also shown in its 7.62x39mm configuration, highlighting magazine compatibility nuances.

Quick Summary

The Beretta ARX-100 achieved 'service grade' accuracy, averaging 2-2.5 MOA at 100 yards. A manufacturer-provided fix for the rifle's rail wobble eliminated physical movement but did not significantly improve accuracy, suggesting other factors were the primary limitation.

Frequently Asked Questions

What accuracy did the Beretta ARX-100 achieve in the test?

The Beretta ARX-100 achieved 'service grade' accuracy, producing groups of approximately 2 to 2.5 inches (roughly 2-2.5 MOA) at 100 yards with tested ammunition like Wolf Gold and Black Hills Match.

Was the ARX-100's rail wobble issue fixed effectively?

Beretta provided a fix involving a roll pin installed in the receiver to stabilize the monolithic rail. While it eliminated physical wobble, testing indicated this fix did not significantly improve the rifle's inherent accuracy.

How did the Robar SR21 perform in accuracy tests?

The Robar SR21, a custom rifle featuring a Remington 700 action in an MDT TAC 21 chassis, demonstrated impressive sub-MOA performance, with one load achieving 3/4-inch groups at 100 yards.

What were the key findings regarding the ARX-100's accuracy limitations?

The testing suggested that the ARX-100's accuracy was limited by factors beyond just the rail's movement. Even after fixing the wobble, the rifle maintained its 'service grade' accuracy, indicating other design elements might be the primary constraint.
