The rotating bolt head has three sturdy lugs that work together at the same time to ensure a greater effective locking surface. The fully tempered steel cover is equipped with holes for attaching scopes and is firmly connected to the barrel to guarantee extremely precise shots. The barrel moves freely and is therefore able to guarantee a precision similar to that of bolt-action models. The fore-end is bound to the receiver and does not interfere with the vibrating movement of the barrel when the shot is fired.
