[9][10] The weapon consists of a large barrel, with a PBO-2 sight mounted to the left.

It is mounted on a small carriage, which has two large wheels, which can be removed.

A small wheel is fitted to the front of the barrel to prevent it touching the ground while being towed.

The tripod can be deployed in two positions providing either a good field of fire or a low silhouette.

Rounds are inserted into the weapon through the breech, and percussion fired using a pistol grip to the right of the barrel.
