Which is more accurate? 1:12 or 1:7 Twist Rate? Let's find out!
This video compares the accuracy and performance of 1:12 and 1:7 twist rate barrels in AR-15 platforms. Testing reveals that the 1:7 twist rate is more versatile, stabilizing both lighter 55gr and heavier 62gr bullets effectively. Conversely, the 1:12 twist rate shows a significant accuracy degradation with heavier 62gr projectiles, making it best suited for clone builds using lighter ammunition.
