Choosing a 7.62x39 Barrel

Barrel length and gas system

Available in carbine/mid lengths; match the gas system to barrel length as with any AR build.

Twist rate

1:10 is standard for the 7.62x39's common bullet weights.

Bolt and magazine note

7.62x39 uses a caliber-specific bolt (different case head) and 7.62x39 magazines — the tapered case feeds poorly from standard 5.56 mags. Plan your build around the correct bolt and mags.
