Cuts, outlines and weight were improved from previous model Lopez type3. The large diagonal cuts for left rotation were changed to alternately semicircle cuts, becoming optimal for any grips and any angles. As a result, this barrel reduces missed shots and transmits force more uniformly.
Moreover, now this model gains stability due to its 20g weight, 1g heavier than previous type. At the same time, its versatility for gripping allows you to use rear-grip, center-grip, and both left and right rotations.
