The 10mm cheek piece spacer is designed specifically for the Sako TRG 22 and TRG 42, offering shooters a more precise and customizable cheek height adjustment for improved comfort and alignment. This spacer kit includes a single black 10mm spacer along with the required extended fastening screw for proper installation. It provides a secure and stable fit on standard TRG stocks but will not fit folding stock models. This 10mm tan spacer delivers a simple, effective upgrade for fine‑tuning cheek weld on compatible Sako TRG rifles.
