What type of rifling does the M110 SASS feature?

• A. 5 grooves, right hand twist, 1 turn in 10 inches
• B. 5 grooves, right hand twist, 1 turn in 11 inches
• C. 6 grooves, left hand twist, 1 turn in 12 inches
• D. 4 grooves, right hand twist, 1 turn in 9 inches

Answer: (B)

The M110 Semi-Automatic Sniper System (SASS) is designed with precision accuracy in mind, and its rifling specifications play a crucial role in achieving that. The correct choice indicates that the M110 features 5 grooves with a right-hand twist and a rate of 1 turn in 11 inches. This configuration enhances the stability and accuracy of the projectile as it travels down the barrel and spins in flight. The 5 grooves allow for a balanced spin, critical for maintaining the bullet's flight path, especially at long ranges where factors like wind and gravity can significantly affect accuracy. Additionally, the right-hand twist pattern is a common standard in modern rifling, which can assist in stabilizing a wide range of commercially available ammunition. The 1 turn in 11 inches twist rate is particularly effective for nominally heavier bullets, typically used for long-range engagements, ensuring optimal stabilization without causing excessive wear on the barrel over time. This specification helps to enhance the overall effectiveness of the sniper system in various operational environments.
