Reply To: .25 Marauder low power tune
I am simply using a 12.5lb hammer spring with zero preload. I order these in bulk from Mcmaster Carr. They are slightly longer and larger wire diameter than stock. My thought in this is simple. I feel a free flowing valve has alot more to offer than a restricted one. You can always restrict the transfer port. The reason behind the heavy spring is simply for hammer bounce.
I have proven in my high power guns that an anti hammer bounce device is not needed. Why? Heavy hammer springs reduce and in some cases eliminate hammer bounce. I tried multiple ssg and ffh designs on my high power guns. Non of them did anything but reduce overall power. The commonality of all these guns are the use of a heavy hammer spring. So, I wanted to try it. Seems like it is working well on this gun.
