External action wrench to remove factory barrel
https://www.midwayusa.com/product/1006553372
To install your prefit you can use the external and snug it up and verify headspace with gauges or buy an internal wrench and torque per the prefits specs. These have been out of stock most normal channels but are listed on ebay. I got one from this supplier in CN (prices are Canadian so USD are less)

Will also need a headspace gauge if you don't have one.
Does kind of add up if you don't have any of this. There are also some posts about methodology people use. I used pitchers rosin and drywall tape to wrap the barrel for grip and packing tape on the receiver.
