Yes, Garandy, you're right. I did suggest that and it was passed along the Armourers chain during the lifetime of the L42 when loose front pads were becoming a problem. It makes engineering sense too
We always used to set the recoil on the layer during range testing to HARD to test the fastness of the graticle and the front pad on the L42's. But the same applies equally to the No4T's
We used to wish that there was a similar simple solution to the dire quality of the fore-ends........
