Webley made actions with both dolls or club head extensions as well as with straight extensions . With later guns such as the 700 they still used the screw as a base for their lever work but abandoned the barrel extension ,effectively making the "grip nut" obsolete . They continued using this as to abandon it altogether would have meant a total redesign of their lever work and at the time the cost of retooling to do so was considered to great. All things considered it was one of the strongest lever systems built as is testimony of the many hundreds of double rifles they built ,mostly bearing the names of other makers .
