This designation refers to a specific model within the Ruger Mark II series of .22 caliber rimfire pistols. The Mark II is known for its reliability, accuracy, and affordability, making it a popular choice for target shooting, plinking, and small game hunting. The “Target” designation signifies features optimized for precision shooting, while “6 7/8” denotes the barrel length, a balance between sight radius for accuracy and overall handling convenience.
Longer barrels generally contribute to increased muzzle velocity and sight radius, aiding in accurate target engagement. This specific barrel length, coupled with the target-oriented design, made this model a favored option for competitive shooting and recreational target practice. The Ruger Mark II series itself holds a significant place in firearms history for its enduring popularity and contribution to the rimfire pistol market.
