This video investigates reports of uncommanded discharges in the MK22 military sniper rifle (Barrett MRAD) following failures to fire. The presenter attempts to replicate the malfunction by simulating conditions described online, including trigger pull, safety engagement issues, and bolt manipulation after a failure to fire. While the specific malfunction was not induced on the presenter's rifle, the video provides insights into potential causes like trigger adjustment and demonstrates the rifle's performance with .338 Lapua Magnum ammunition on various targets.

Quick Summary

Reports indicate the MK22 sniper rifle (Barrett MRAD) may experience uncommanded discharges after failures to fire. This malfunction involves the rifle discharging when the bolt is manipulated, often after the safety fails to re-engage. This differs from a hangfire, suggesting a mechanical issue.

Frequently Asked Questions

What is the reported problem with the MK22 sniper rifle?

Reports suggest the MK22 sniper rifle (Barrett MRAD) can experience uncommanded discharges. This typically occurs after a failure to fire, where the rifle discharges unexpectedly when the bolt is manipulated, often after the safety fails to re-engage.

How does the MK22's malfunction differ from a hangfire?

A hangfire involves a delay in ignition after the primer is struck. The MK22's issue is described as a failure to fire where the primer isn't struck, but the rifle discharges later when the bolt is cycled, suggesting a mechanical issue rather than a slow ignition.

Can the safety on the MK22 be re-engaged after a trigger pull?

According to reports and the presenter's observation, the safety on the MK22 cannot be returned to the 'safe' position after the trigger has been pulled, even if the rifle fails to fire. This indicates the hammer has been released sufficiently to prevent safety engagement.

What caliber is the MK22 sniper rifle and what is its performance like?

The MK22 sniper rifle is chambered in .338 Lapua Magnum. This powerful round demonstrated significant destructive capability, completely disintegrating a 50-pound salt block and leaving substantial impact marks on steel targets.
