I have an old in the box DT Mauser 98 trigger/speedlock kit.
Price on the box is $13.50, so day or two old.
I have no interest in the speedlock, but is the trigger different? or can it be used in a 98 as is?

I have one of those on a 1903 Springfield. It is definitely a better trigger than the milsurp. It should be a drop in fit if it is for a 98.

The spring tends to break, are they still in business. Sell it and get a Timney would be my approach.
