Lee Breech Lock Challenger Quick Lock Bushing Two Pack 90600

Great product and makes switching between dies and calibers very easy. Allows you to keep all settings and swap dies. Very handy. Pros: Definitely a great product and well worth the expense Cons: have to have one for each die you own; can get pricey.

Good item and even better price. Pros: cost, quality Cons: none

Well made well engineered product at a fair price. Thats top quality in my book. The outside diameter is a proprietary thread with 3 starts. Drop the bushing into the press and it tightens and locks in a third of a turn. Holds adjustments well

As the title says, you can never have too many of these. When you think you have enough then you need a couple of more. There are cheap enough to keep a few extra around. I wish they would fit a little tighter, but they work just fine.

Makes changing out my dies quick and easy. Minimal adjusting when setting them up.

These bushing are a piece of cake when using them in a Lee press. Once your dies are set, this is a one hand operation when switching out to another die. Quick and fast. I have my dies set up so I do not have to push the release button on the press to change dies. I would recommend these dies bushings for any LEE press.

Made setting and replacing dies a snap. By having extras I can leave them on so die settings stay in place. Pros: Fit perfect, easy to use Cons: none

These bushings are well made and make a using a lee single stage press fast and easy. optics planet consistently has the best price unless someone has a sale. I have these for all of my dies and will continue to get them.
