A pistol-length AR-platform firearm chambered in a specific intermediate cartridge, featuring a 7.5-inch barrel and graded at 7.5 by Professional Sports Authenticator (PSA), represents a popular configuration for close-quarters engagement and other tactical applications. This combination of barrel length, cartridge, and grading signifies a balance between maneuverability, stopping power, and collectible value. The authenticator rating provides an independent assessment of the firearm’s condition, impacting its market worth.
Compact carbines in this caliber offer advantages in confined spaces due to their reduced length and weight, while the cartridge maintains effective ballistic performance at shorter ranges. This makes them suitable for home defense or competitive shooting scenarios. The specific grading from a respected authenticator adds a layer of desirability for collectors and enthusiasts, often reflecting the firearm’s condition and potential for appreciation in value. This convergence of practicality and collectibility contributes to the popularity of this specific firearm configuration.
