Profile: The barrel has a "light" profile, which typically refers to a thinner and lighter barrel contour, aiding in reducing overall weight.
Length: The barrel is 16 inches long.
Twist Rate: It has a 1:3 twist rate, which means the rifling inside the barrel completes one full rotation every 3 inches. This twist rate is not commonly used, and it's possible that there might be a typographical error. The more common twist rates for 5.56/.223 caliber barrels are 1:7, 1:8, or 1:9.
Caliber: The description mentions "8.6 Blackout," which could refer to .300 Blackout or a similar caliber compatible with the Q Fix rifle.
Finish: The barrel has a "Matte Stainless Finish" in gray. This suggests that the barrel has a stainless steel construction with a non-reflective matte finish.
