What mechanical issue can arise from poor assembly of a rifle?

Inconsistent firing is a common mechanical issue that can arise from poor assembly of a rifle. When a rifle is not assembled correctly, various components may not align properly, which can lead to variability in how the rifle functions. For instance, components like the trigger mechanism, bolt assembly, and barrel alignment must work in harmony for reliable operation. If any of these parts are misaligned or improperly secured, it can cause the rifle to malfunction, leading to unpredictable firing experiences and variations in accuracy. Inconsistent firing may manifest as failures to fire, misfires, or erratic shot placement, all of which can undermine a shooter's performance and confidence in the firearm.

The other options relate to different aspects and do not accurately reflect the consequences of poor assembly. Improved accuracy and enhanced ergonomics would typically require a well-constructed rifle, while aesthetic degradation may be a byproduct of poor assembly but does not directly impact the functionality of firing the rifle.
