Which statement about stock modification rules is true?

Which statement about stock modification rules is true?

• A. Targets bearing NRA insignia are required.
• B. There is no rule governing the butt identity when modifying a stock.
• C. The butt may be modified to any shape.
• D. When shortening or lengthening a stock, the butt must be identical to the original equipment.

Answer: (D)

Stock modification rules are about keeping equipment dimensions and how it feels when shouldered within approved limits. The statement that the butt must be identical to the original equipment whenever you shorten or lengthen a stock makes sense because the butt serves as the fixed reference point for the stock’s length and how the gun sits against the shooter. Requiring the butt to remain the same ensures the changes don’t unintentionally alter the length of pull, balance, or shoulder contact in a way the rules didn’t anticipate. It also makes compliance easy to verify for officials since the butt is the part of the stock that defines the basic fit to the shooter. Other ideas would either let modifications change how the gun is shouldered or would ignore the established reference point for measurement. There isn’t a rule about needing NRA insignia as part of stock modification, and the butt cannot be freely reshaped—its identity must stay consistent when length changes are made.
