What is a key feature of the SVD rifle?

The key feature of the SVD rifle is its fixed buttstock. This design is integral to the rifle's overall structure and function, providing stability and contributing to the rifle's accuracy. The fixed buttstock allows for a consistent and reliable shooting position, which is especially important for a designated marksman rifle like the SVD, designed for precision at longer ranges.

While other features such as a rotating bolt mechanism, detachable magazine, and variable optic system may play roles in various rifles, they are not defining characteristics of the SVD. The fixed buttstock is specifically tailored to provide optimal support and align with the weapon's intended use in the field. This design choice reflects the balance between portability and control, ensuring that the rifle can be operated effectively in various combat situations, which is crucial for a marksman operating with the SVD.
