Cmmg Ejection Port Cover Kit Mk3

The CMMG Ejection Port Cover Kit Mk3 is a precision-engineered accessory designed to protect the ejection port of .308-caliber rifles from environmental contamination, debris, and corrosive elements. This kit includes the cover itself and a spring mechanism for quick, tool-free installation and removal in the field. It is ideal for tactical shooters, competitive rifle competitors, and hunters who deploy .308-caliber platforms in challenging environments.

The kit's compact design reflects thoughtful engineering for active shooters who need to maintain bolt-face and gas tube cleanliness without sacrificing speed of access. The spring-loaded mechanism allows the cover to flip open on demand while remaining firmly closed during storage or transport, preventing dust, sand, and moisture from entering the action. Weighing just 0.06 pounds with dimensions of 4.5 x 0.25 x 2.5 inches, the Mk3 adds negligible weight while delivering meaningful protection to a rifle's internal systems.

Whether training in dusty ranges, hunting in arid terrain, or maintaining rifles in vehicle-mounted or field-stored configurations, the ejection port cover kit preserves long-term action integrity and reduces maintenance demands between cleanings. This accessory is essential for maintaining the reliability of your rifle in various environmental conditions. Trust in the quality and performance of CMMG products to enhance your shooting experience.
