The KT variant of the HW100 is the thumbhole carbine version. The thumbhole design is probably the most attractive of the HW100 and it is also the favourite amongst precision shooters. A thumbhole stock enables the shooter to place more skin on the stock and this helps the shooter control the rifle. The Stock is made from quality oiled walnut and is fully ambidextrous. There are also finger groves in the fore end for extra stability, couple this with a carbine length barrel and you have what is often described as the ultimate HW100
