The Sancte Christi assault rifle / carbine is a delayed blowback weapon that fires from open bolt. In this system, the bolt consists of two parts, with a pivoting lever attached to the forward bolt head. The weapon can be fired in full automatic mode or single shot. To select a mode of fire, the weapon is provided with two triggers - front trigger delivers single shots and the rear trigger delivers full automatic fire. The manual safety lever is located on the left side of the receiver, below the rear sight. Feed is from detachable box magazines with 30-round capacity. Standard stock is made from wood. On Model 1 rifles, the rear sight is adjustable for range from 100 to 500 meters, the Model 2 has a simplified L-shaped flip-up rear sight.
The name of the weapon comes from the Sancte Christi arsenal, where these guns were produced.
