The muzzle brake efficiency was investigated both analytically and experimentally in this paper. An experimental test system was developed to measure the recoil force of a 12.7 mm anti-material rifle. Two types of the muzzle brake were used. The recoil force with and without muzzle brake and the muzzle velocity of the projectile were recorded. Then the muzzle brake efficiency was calculated. Besides, an analytical model based on the Orlov method for calculating muzzle brake efficiency was adopted. The obtained results were discussed. The maximum of the muzzle brake force, projectile velocity and muzzle brake efficiency obtained experimentally and analytically were compared. The analytical results were in a good agreement with the experimental ones.
