The Cheek PROV1 is a new version of the Centra Cheek product.
Like previous versions, a threaded spindle ensures shooters can adjust the cheekpiece steplessly to the side while in position.
An intermediate layer made of vibration-damping plastic and special fixings isolate the cheekpiece from the stock. This helps to absorb reverberations, vibrations and the shooter's pulse, which would otherwise betransmitted from the cheek to the stock.
We're not talking about strong vibrations here, but rather the very light vibrations, which translate into tenths on the target.
