Design Philosophy
This stock prioritizes shooter comfort and control. The integrated cheek weld helps establish a repeatable shooting position, while the rubberized buttpad absorbs recoil and prevents slipping during shouldering. The lightweight composite material reduces overall rifle weight without compromising structural integrity—a consideration that matters over the course of a long shooting session.
Whether you're building a new rifle or upgrading an existing platform, the GL-Core delivers practical improvements in handling and shooting consistency.
