Duration: 18:18

This review of the Global Ordnance Monolith rifle, with over 600 rounds fired, details its accuracy performance with various 5.56 and .223 ammunition types at 100 yards. The presenter, Mark, also addresses reliability issues encountered when shooting suppressed, specifically light primer strikes, and offers workarounds. The video highlights the importance of ammunition selection and recoil spring tuning for optimal suppressed performance.

Quick Summary

The Global Ordnance Monolith rifle experienced light primer strikes when shot suppressed with its dedicated springs. This issue was resolved by switching back to the standard recoil springs, which allowed for reliable suppressed function. Accuracy varied significantly by ammunition type, with Winchester M855 62gr performing poorly.
