Brocock Bantam Hampster mounting help

The Bantam is being setup to use for field target in both Hunter and Open class.I want to mount a removable hamster to the Bantam doing the least damage to the stock as possible. The best idea I have so far is to drill out the front swivel stud mounting hole in the stock, and insert a "T" nut from the inside, and glue it in place. Then, I can insert a screw from the outside to hold the hampster. A piece of leather between the hampster and stock will prevent damage to the stock. Any suggestions will be helpful.
 
You can install swivel stud, or small section of weaver rail in the front.
If you decide swivel stud, you can add bipod adapter

than you can connect hamster to one of the old scope rings and mount it to the rail when you need.

Good idea. I may be able to make something that will work. A cylindrical adaptor form the top MAC1 hamster to the scope ring might do the trick. Since I'm long wasted I need more height. I was planning to use one of the knee rests from MAC1 Airguns. Here is his picture of one from his website. Pyramyd Air has swivel stud with a bipod adaptor. I'll look into it. Thanks again.
