There were a number of issues with this design, some which were expected, some not:
]
[*]The foreend was REALLY hollow - fine as far as deflection & stiffness, but it had the result of resonating when you cycled the bolt
[*]I also screwed a sling stud into this, which obviously ripped out after not very long
I have a couple ideas that may be too late. To stop the sling stud pulling out we use the nut type that has a nut on the inside and a washer to spread the load over a greater surface area on the internal. You could also use a layer of fibre glass or similar to help there. The second version where it is not a single cavity looks to be a better version / idea.
All the best and I watch with anticipation.
