Ruger 90431 American Rifle Stock Module Synthetic Black Low Comb

The Ruger 90431 Stock Module transforms the American rifle platform with a precision-molded synthetic construction that delivers consistent performance across varied shooting conditions. This replacement stock addresses common ergonomic issues while maintaining the rifle's proven accuracy standards.

What Makes This Different

The low comb design positions the shooter's eye naturally in line with standard scope heights without requiring cheek risers or uncomfortable head positioning. Unlike higher comb stocks that force awkward shooting positions, this module accommodates a wide range of optic configurations while maintaining proper sight alignment. The standard length of pull measurement ensures compatibility with most adult shooters without modification.

Key Features

• Low comb profile optimizes scope alignment for standard ring heights
• Standard 13.5-inch length of pull fits average adult frame dimensions
• Glass-filled nylon construction resists impact and weather exposure
• Factory-engineered bedding surfaces ensure consistent barrel contact
• Integrated sling swivel studs positioned for balanced carry
• Textured grip surfaces provide secure hold in wet conditions
• Compatible with all Ruger American rifle actions and barrel configurations

Field testing demonstrates the stock's ability to maintain zero through temperature fluctuations and rough handling typical of hunting scenarios. The synthetic material shows no warping or dimensional changes when exposed to moisture, unlike traditional wood stocks that can shift point of impact. Competition shooters appreciate the consistent cheek weld that eliminates variables in scope positioning.
