Would cost more...and I believe the only tools that they have that are worth buying are specialty (expensive and unlikely to use more than a couple times) and air tools...which are still of dubious (marginal at best) quality IMO. That said, everyone (to include women, children, and primitive screwheads) needs to have basic hand tools. A wise man (Walt Kowalski played by Clint Eastwood in Gran Torino) said: Take these three items, some WD-40, a vise grip, and a roll of duct tape. Any man worth his salt can fix almost any problem with this stuff alone.Hint...Harbor Freight!
If the existing crown is *really* bad (like you just hacksawed the barrel and did a bad job of it) maybe use Clover valve grinding compound instead of JB.
The ideal crown will have it's face exactly 90 degrees to the bore and be burr free and as smooth as possible. This enables the bullet and it's gases to exit as evenly as possible.
