PT-91M Pendekar use a new improved 2A46MS main cannon. The breech block has been redesigned to make it more symmetric, decreasing the resistance of the recoil break whilst the projectile is moving in the barrel, removing the recoil break axis below the main cannon axis in the azimuth plain, using two recuperators acting against each other and placing them above the main gun axis.
This has increased first hit probability by 23% over the original 2A46M main cannon.
