Was checking and your options seems to work. If I select some the options, the price changes accordingly . Based on the wording, you can make a variant for Active Pickups & Chambered and then the price to $2300. There is a request from the Wix Stores team to be able to sell customizable product options that you can vote on here .
If you do want to go the Velo route, these examples may help but would suggest visiting the Velo forum as Certified Code mentioned.
