That product name appears to be a specific model number for a manual mortar or pointing gun, often used for applying cement mortar into brickwork joints, tile gaps, or for grouting.
The breakdown is:
ABS: Refers to the main construction material, Acrylonitrile Butadiene Styrene, a type of strong, durable plastic often used for the body or barrel of the gun. This makes the gun lightweight but robust.
MORTAR GUN / CEMENT GUN: The tool's function. It is a large-capacity caulking gun designed to dispense wet mortar, cement, or grout (not standard caulk) more easily and precisely than traditional trowel methods. This is particularly useful for:
Repointing: Filling in old or damaged mortar joints between bricks or stonework.
Grouting: Filling joints between patio slabs or large tiles.
