What Adjustments Should Be Made When Switching to Carbon Fiber?

Mounting and Alignment

When transitioning to a carbon fiber stock, ensure the scope mounts are securely attached and aligned with the rifle’s action. Most carbon fiber stocks require a 11mm or 17mm rail system, so you’ll need to use compatible mounts. For example, if you’re using a Leupold scope, use their 11mm quick-release rings. Also, verify the rail spacing; some carbon fiber stocks have a 20mm or 30mm rail, which may require an adapter.

Action Sling and Bolt Location

The bolt location on a carbon fiber stock typically needs to be slightly adjusted to accommodate the rifle’s bolt handle. This adjustment ensures a proper fit between the stock and action. If necessary, you can use a bolt stop or a bolt guide to secure the bolt handle in place. When attaching a sling to the action, ensure the sling is positioned on the correct attachment points to avoid interference with the bolt.

Stock Fit and Action Clearance

To ensure a proper fit, check the action clearance between the stock and the rifle’s action. This clearance should be about 1/8 inch (3 mm) to allow for smooth bolt operation. If the clearance is too tight, the bolt may bind or the stock may crack. To prevent this, you can use a stock shims or adjust the stock’s bedding to achieve the correct clearance.
