How to properly adjust a Bergara stock for better fit?

Measuring the Rifle

To begin the adjustment process, use a rifle stock measuring tape or a digital caliper to measure the rifle’s length of pull (LOP) and the length of pull to the trigger (LOP to trigger). The LOP is the distance from the center of the trigger to the end of the stock, while the LOP to trigger is the distance from the center of the trigger to the tip of the shooter’s nose. Aim for a LOP of 13-14 inches for most adult shooters. Use a ruler or measuring tape to measure the comb height from the stock’s surface to the top of the comb.

Adjusting the Comb Height

To adjust the comb height on a Bergara stock, use a shim or a stock lift to raise or lower the comb. Start by placing a shim between the stock and the action, then use a scale or a set of weights to adjust the shim’s thickness. For every 1/8 inch of shim material, the comb height will increase by about 0.6 mm. Check the comb height after each adjustment, using the measuring tape to ensure it’s aligned with the shooter’s eye line. For most shooters, the comb should be about 1.5-2.5 mm above the eye line.

Final Check and Adjustments

Once the comb height is adjusted, check the forearm fit by ensuring the shooter’s hand fits comfortably into the forearm without obstruction. Adjust the LOP if necessary, adding or removing material from the stock’s cheek weld to achieve a comfortable fit. Use a marker to mark any adjustment points, and take note of any future adjustments to be made. Finally, check the rifle’s balance by holding it at the shooting position, ensuring the barrel and stock are evenly balanced.
