I recently purchased a Stoeger X20 .22 cal and after I replace the scope I decided that I needed a bipod. I didn't want to mount a bipod to the barrel so I searched the web and purchased a rail kit and a two piece bipod from amazon.com for less than $30 and free shipping yay! So here is the sequence and how I mounted it:
Rail kit purchased from amazon.com. I didn't know it when I order the kit that the rails are made of plastic and not aluminum, but that wasn't a problem.
Had to figure out exactly where to mount the rails so that they would be rigid on the fore-stock.
.
Applied tape to the both sides of the stock and marked the hole locations.

It was easier and quicker for me to drill the hole into the fore-stock with a hand drill instead of using my drill press.

Once the holes were drill I mounted the rails on both sides of the stock with the screws/nuts supplied with the kit.


Not shown in this pic, but I had to remove portions of the screws protruding past the nuts inside the stock so that they would not interfere with cocking the rifle.

Finished product with the two piece bipod mounted.

Overall I'm very happy with the addition of the bipod, it's rigid, sturdy and made a big difference. Hope this was helpful
