The swivel stud adaptor will likely involve removing the swivel stud completely and putting a through bolt and using a big washer/nut on the 'inside'. Swivel stud themselves aren't all that strong and with a rigid pod, the recoil forces will move to the stock - that is the whole point.
Without internal support, a stud is going to pull out of a composite stock. If there is a threaded block already in the stock, then that is a different story. Let me know.
If you can, we would recommend adding a short length of T slot rail. That is simply the best, strongest and least cluttered way to use this pod.
The next batch of pods will be hard coat mil spec Type 3 anodized in a matte black. We can also duracoat/armacoat the pod for you here but you wil likely find the anodizing pretty durable on its own - or send to Murdoch.
Let me know...
