The B4 over-and-under combination rifle/shotgun combines precision with safety. Finely tuned triggers combined with a single box lock enable highprecision shooting. The single lock manual cocking system on the stock wrist allows the gun to be carried in a decocked status, and rapidly cocked when required. The rifle barrel adjustment under the forearm is a technical delicacy. The high-grade processing right up to the steel middle barrel rail is characteristic of the gun as a whole.
