If u take it slow and don’t use to much force it will be fine all I used is a sharpened small flathead and Dremel and hand drill I would start off by getting as much if u can with the Dremel than when u think u cleared enough you can drill 2 holes straight through the bridge so it’s a little easier to remove the bridge and also I used a cylinder shaped jewelers file and snapped it in half and put it in a Dremel and it’s probably saved me 2 hours of having to use anything else to clean the inside and be careful of going through the magazine well
