The Barrett MRAD / MK22 is a U.S. multi-caliber bolt-action sniper rifle family used here as a relationship-only support record for chambering and rifle-system context. Army and Marine Corps sources identify the MK22 as a modular Barrett MRAD-derived sniper system fielded with 7.62 mm, .300 Norma Magnum, and .338 Norma Magnum barrels, while Barrett's MK22 page lists .300 Norma Magnum configuration details.
This record groups the Barrett commercial MRAD family with the U.S. MK22 ASR and PSR service configurations only where official sources tie the systems together.

The MK22 is represented as a support page because the sources used here document service adoption, modular chambering, and cartridge compatibility rather than direct conflict use by this catalog record.
