1:7

In the firearms industry, a 1:7 twist rate is crucial for AR-15 rifles. It indicates the barrel’s rifling rate, where the bullet completes one rotation in seven inches. This twist rate excels with heavier bullets, such as 62 grains or more, offering improved accuracy. Many users prefer this rate for its versatility, as it balances well with different bullet weights. When choosing AR-15 parts and accessories, especially barrels, understanding the 1:7 twist’s advantages helps enhance shooting precision. Whether for tactical applications or competitive shooting, the right twist rate can significantly impact performance.
