I have one in my 1895 CB.
Made a huge improvement. I have it written down somewhere. Seems I went from around 7lb grainy pull, to around 2lb smooth.
Very pricey. When you look at the thing you will think you have been swindled. worth every penny. Best mod for a marlin in my opinion.
Don't know who has the best price, but I'm betting Cabela's.
Dropped right in. Couldn't wait to shoot it. You will like your gun even more.
