The Walther 1250 Dominator implements the proven engineering of the successful Walther LG300 Dominator in a compressed-air repeating system with 8-shot rotary clip. The boltaction feeds the pellet directly into the barrel, resulting in precise long-distance shooting with minimal velocity reduction.

The gun comes with fiber optic front and rear sights. The fiberglass-reinforced synthetic stock has a Monte Carlo buttstock with cheekpieces on both sides. The textured forearm and pistol grip make it easy to have a firm grasp at all times. 300-bar-tank with manometer and spare magazine clip included. This is the most-powerful version in 4,5 mm.

In Germany it is necessary to obtain a permission to purchase certain weapons according to the gun law. Please note the corresponding regulations for your country.
