Which feature enhances the accuracy of the M110 SASS?

• A. Use of high-velocity ammunition
• B. Standardization of barrel length
• C. Effective rifling design
• D. Lightweight construction

Answer: (C)

The feature that enhances the accuracy of the M110 SASS (Sniper Anti-Material System) is effective rifling design. Rifling is the process of cutting grooves into the barrel of a firearm, which imparts a spin to the bullet as it is fired. This spin stabilizes the projectile in flight, improving accuracy significantly.

The effective design of the rifling in the M110 SASS optimizes bullet performance, allowing for greater precision over longer distances. The twist rate, groove depth, and shape of the rifling can all affect how well the bullet performs, ensuring that it maintains a stable trajectory and consistent flight path. Therefore, having a well-engineered rifling system is critical for a sniper platform like the M110 SASS, making it essential for achieving high levels of accuracy in various conditions.

In the broader context, while high-velocity ammunition can contribute to flat trajectory and reduced time of flight, and the standardization of barrel length provides consistency in manufacturing, these factors alone do not directly influence the stability of the bullet in flight as effectively as the rifling does. Similarly, lightweight construction may improve mobility but does not enhance the inherent accuracy of the platform.
