Substantial Improvement
These are a well thought out and well made alternative to grinding the stock leaf springs or loosening the mounting screws to achieve a lighter and smoother lever action. I installed them in my late production Uberti 1866 and the action now rivals friends rifles with $150.00 pro action jobs. I just ordered another set for a new 1873 as well. Make sure to order the screws that compliment the kit as the stock items are very soft and (I think) a different thread pitch.
