This Is What Subsonic Rifles Should Have Always Been
The Garand Thumb review highlights the Robinson Armament XCR-M in 8.6 Blackout as a significant advancement in subsonic rifle platforms. It offers superior terminal ballistics compared to 300 Blackout and 9mm subsonic rounds due to its heavy 300-grain projectile and high twist rate. The rifle demonstrates manageable recoil, acceptable accuracy for its intended role, and impressive modularity with its quick-change barrel system.
