XTS 106 AR-15 Stock with Adjustable Cheek Rest, Matte Black The XTS 106 stock combines AR-15 fit with an adjustable cheek rest and a matte black finish. The cheek rest provides the stock's cheek-contact area, with adjustment offering a way to vary that support position. A cheek rest supports the side of the face at the stock, and an adjustable version allows that contact position to change. This is useful when comparing stock shapes and cheek support for an AR-15. The matte black finish gives the stock a subdued appearance alongside matching rifle furniture.
