Canadian Restricted and Non-Restricted Firearm Safety (CRFSC) Practice Exam

The correct answer is that a scope is not considered a major part of a non-restricted firearm. A non-restricted firearm typically includes essential components that are critical to its function and operation. These include the stock, action, and barrel, all of which play vital roles in the mechanism of the firearm.

The stock is the part that provides stability and support when aiming and shooting. The action is the mechanism that loads, fires, and ejects the cartridges, forming the core operational element of the firearm. The barrel serves as the tube through which the projectile is expelled and is fundamental to the firearm's accuracy and performance.

On the other hand, a scope is an accessory that enhances aiming and sighting but is not essential for the firearm to operate. A firearm can function without a scope, as it is generally designed to operate with or without additional sighting equipment. Thus, the scope is categorized separately as an accessory rather than a major structural component of the firearm itself.
