What can happen if firearms are not properly maintained?

When firearms are not properly maintained, they can indeed become less accurate. Regular maintenance is critical for ensuring that all components of a firearm function as intended, including proper cleaning, lubrication, and inspection of parts. Over time, dirt, fouling, and wear can accumulate, adversely affecting the firearm's mechanical systems and its ability to achieve consistent firing results. Factors such as a dirty barrel, worn-out sights, or malfunctioning actions can lead to decreased precision and reliability, resulting in a loss of accuracy when aiming or firing.

The other options do not accurately reflect the consequences of poor firearm maintenance. For example, firearms are unlikely to gain value if they are not maintained; in fact, neglect can lead to degradation in condition, which typically decreases value. Additionally, a lack of maintenance does not cause firearms to fire more rapidly; rather, it may lead to malfunctions or failures to fire altogether. Finally, failing to maintain a firearm properly does not mean it will require less cleaning; instead, it will often depict an increased need for cleaning and repairs as issues accumulate.
