Ruger 30mm Med(4) Mst (4k30hm) Indv

The Ruger 30mm Medium Ring with Matte Stainless Finish (model 4k30hm) is a precision optic mounting solution designed for riflemen who demand factory-engineered reliability and durability. This medium-height ring is engineered to accommodate objective lens diameters up to 42mm, making it ideal for mid-range scopes on hunting rifles, tactical platforms, and precision shooting systems. As a genuine Ruger factory accessory, this mount delivers the same quality control and fit specifications that Ruger applies to its firearms themselves.

Constructed from durable stainless steel with a matte finish, the Ruger 30mm medium ring resists corrosion and glare while maintaining a professional, low-profile appearance on the receiver. The matte stainless surface prevents light reflection that could compromise shooting positions and withstands harsh field conditions, from rain and humidity to dust and temperature extremes. The medium ring height positions your scope at an optimal sight picture relative to your rifle's bore axis, reducing head positioning errors and improving cheek weld consistency across different shooting platforms.

This Ruger mount ring is best suited for hunters, sport shooters, and tactical operators who are equipping Ruger rifles or compatible 30mm picatinny receivers with quality glass. The 30mm tube standard accommodates most modern hunting and tactical scopes in the mid-power range, and the medium ring height works particularly well with standard-height receiver rails. Installation requires proper scope mounting technique and compatible Ruger or universal 30mm scope rings; refer to your rifle's manual for torque specifications and mounting orientation to ensure optimal performance and zero retention.
