The black 3 mm cheek piece spacer for the Sako TRG 22 and TRG 42 allows for precise adjustment of cheek height to improve shooter alignment and comfort. It provides a small but effective lift for achieving a consistent and repeatable cheek weld, enhancing accuracy during extended shooting sessions. Designed to fit securely on standard TRG stocks, this spacer maintains the solid feel and reliability expected from Sako components and is not compatible with folding stock models.
