K-Optima Drilling

About the Optima Drilling


The combination of double shotgun barrels with a rifle barrel centred beneath, has been the classic drilling configuration for generations. Forest masters and hunting experts all over the world appreciate the versatility a drilling provides.

The Optima drilling Thermo Stable is available in the most common shotgun gauges, as Optima 12 and 20. The Optima optionally with steel or duraluminium action, both versions are proofed for steel shot (Lily). On request we still built the Optima with the traditionally soldered and therefore very slim, light barrels.
