GPO Ballistic Turret

With the GBT ballistic turret, GPO meets the wishes of many customers and offers a unique and quick reticle ballistic adjustment: The standard turret of the SPECTRA 1,6-13x44i can be replaced with the optionally available GBT in just a few seconds. The ZERO-Stop already installed in the standard version of the SPECTRA 1,6-13x44i can be used with both turret variants. The GBT has 5 superimposed rings for distance up to 500 m.
The turret can be locked and is therefore securely protected against unintentional adjustment.
