If you choose a stock without a mini chassis, you must have it glass bedded with pillars. At minimum, the pillars must be installed and the lug area bedded. The pillars prevent stock crush over time, keeping the torque values consistent. We build our stocks with tolerances needed for a competent gunsmith to bed your action. The glass bedding will ensure your action stays secure and is repeatable for a lifetime of use.  The bedding will give a mirrored fit of your barreled action and will help with accuracy, repeatability, and longevity.
