The 24-inch varmint-configuration AUG A3 M1 is the longest barrel option offered for the platform, purpose-built for precision varminting and long-range target shooting. The heavy barrel profile and extended length reduce muzzle velocity variance and provide a stiff, harmonically consistent tube. The bullpup layout keeps overall length manageable despite the long barrel. The 1:9 twist is optimized for 55-77 grain .223 Rem projectiles.
