It doesnt seem like adding weight to the hammer will really do anything since its going to move slower... If you add twice the weight, you can expect it to move half as fast. For the people who did add weight to the hammer could you notice a difference with just the hammer weight alone?
I noticed when looking though the gun that there is plastic in front of the hammer that prevents it from going to far forward. Seems like its a safty to keep the gun governed to a slow fps, i just removed it.
does make a difference. It wont make you gun shoot 800 fps but i saw an improvement. What happens is the hammer hits the valve with more force causing it to "dwell" open longer realeasing more c02 which increases fps. That coupled with a tighter hammer spring will give it more momentum and energy than the stock set up. When adding weight, the hammer probally does go slower but it has more energy. A perfect exapmle is how the same model gun shooting a .22 pellet will give more ft/lbs then a .177 version.
So your saying you just cut out that plastic wall? You may be on to something, but the valve pin can only compress so far and i think it can be fully compressed and still stick out from the wall. I would have to take apart the gun to be sure. If yours is still apart take the valve and seat it in its place. Then using your finger push the pin all the way in and see if it is still past the wall. If its not, taking out the plastic could possible add some good fps. If you do try it post the results.
If you look at the top of the hammer, youll see a single step in it. Then if you look at the plastic housing above it youll see some plastic there that fits into that step. I cut that out also.
is it possible to "drill" out, like drill into the hammer and make a pocket, the hammer without destrying it? and if this is possible couldnt u do this and just ad a stronger spring? or would the orig spring work fine?
