I installed the zkh in my marker with the stock spring as recommended. After installing I could not get my velocity up to where it was at with the stock hammer. With the stock one I was at a steady 295 to 300 fps. The best I could get with the zkh was 240, average was 218 fps. After I took the zkh out and put my stock hammer back in, I still could not get velocities up past 240. I tried with stronger springs and the results didn't change.
If you want to spend the money and it works for you, cool. If you like shiny things then this is for you. It didnt work for me or any of the six guys here that bought one. The guns were A5's and BT Deltas. The customer service from Tech T was awesome. I am in no way bad mouthing them. Im just giving my review of this product in my opinion.

So you put in the new hammer, and it kills your velocity. You then put back the stock hammer, and your velocity is unchanged. Doesn't that rule out a problem with (either) hammer? You have other issues that need to be addressed.
