RFI NoI Mk3 in grease.

[Ridolpho]

OK, now I'm getting confused (not unusual). In the big Skennerton book he mentions that the application of the 2.5 inch cup to the No. 4 rifle failed because the full recoil loading was put on the barrel whereas with the No. 1 rifle part of the loading was taken up by the nosecap/ forend. Looking at my own wire-wrap Ishapore, I can adjust the inner stub in the cup base such that at firing both barrel and forend will take up recoil. As Peter L. says, it it (the cup) is to be adjusted for the individual rifle which will have slight variance in barrel protrusion beyond the nosecap. If it was intended that all recoil was to be taken by the barrel that adjustable stub seems pointless. The way the Indians modified their grenade launcher rifles (extra heavy bolt in place of "Ishapore screw", apparently, in some cases, rubber pads behind forend, and the wire or sheet metal wrap) it would appear they expected the forend to take a heavy beating from grenade launching. The cross bolt and wire wrap could certainly protect against splintering of the forend. What am I missing?
