A straight pull, interchangeable calibre, take down rifle with quick mount scopes and barrels. They sound impressive.
The STRASSER RS 05 straight-pull offers as factory standard easy calibre changes through barrel replacement via hydraulic barrel clamping. With this novel system (patent pending), the barrel is held in the receiver ring by constant, circumferential hydraulic force.
Unlike other systems using simple clamping bolts, the barrel is held with a constant uniform presure. This is a system that guarantees the same clamping pressure for a perfect return to zero every time - without the use of a torque wrench.

Also in wood too for Dromia
