Nice job. Suggest you only drill as deep as the stud screw, not all the way through the stock. Looks nicely professionally mounted although I prefer the picatinny mount.
Ive done the same but another option for anyone wanting not to drill holes is the picatinny barrel rail that sits around your barrel and front air cylinder also sits your bipod a little more forward 👍 but only if your bipod has the picatinny option
And also fitting the bipod on the barrel rail means you can still hold the rifle stock nicely when you don't want to use the bipod, i.e. prone shooting.
