I can see that the mechanism is another means to achieve an end but is it a commercial means of tightening up the fore-end to achieve greater accuracy or a military idea to save patching the draws? Any Military input at all?
Just another Q following on from RJW (#16 below.....). Are the rods adjustable in any way? It doesn't look like it but by definition they MUST be due to the fact that every rifle is slightly different - that's why we have to FIT a fore-end!
