Which statement about stock length modifications is true?

• A. Hook butt plates are allowed.
• B. Thumbhole stocks are mandatory.
• C. When shortening or lengthening a stock, the butt must be identical to the original equipment.
• D. Stocks must be painted black.

Answer: (C)

Stock length modifications are about keeping equipment consistent and safe. When you shorten or lengthen a stock, the butt must be identical to the original equipment. This requirement keeps the rifle’s balance, contact point, and shoulder fit the same, so changes in length don’t alter how the rifle sits, points, or feels in use. That consistency helps ensure fairness across competitors and avoids giving an advantage from altering the butt. The other statements don’t fit because a hook butt plate would change how the rifle sits on the shoulder, which isn’t allowed for standardization; thumbhole stocks aren’t required in all cases and are simply one allowable option among others; and painting the stock black is a cosmetic detail, not a rule about modifying length or fit.
